Introduction

Introduction to the Ohio HSIS Guidebook

The Ohio data system that is provided to HSIS includes the following basic files:

  • Accident data:
    • Accident data (Accident, vehicle and occupant)
    • Roadway Inventory File
    • State Supplemental Inventory, containing curve and grade data
    • “Points” File (intersections, railroad grade-crossings, underpasses, etc.)

Data from all of these files are captured by HSIS. Raw file data are provided to the Highway Safety Research Center where they are retained as backup information. The documentation (variable listings, definitions, etc) for these raw files and for the SAS files that are developed from them is available at FHWA offices. The conversion programs developed by HSRC and LENDIS to convert the files into SQL and SAS formats are also available at the HSIS offices at FHWA.

Beginning in 2004, the HSIS system was converted from a SYBASE relational database to an ORACLE relational database for internal use. Data files for a given State are linked and manipulated by HSIS staff using SAS code and, as in the past, we have continued to produce SAS format libraries for each of the variables in each of the files. This Guidebook will concern these SAS files - their formats, completeness, and quality. However, researchers requesting data from HSIS can request the output in various formats such as SAS, Microsoft Excel® and Access®, dBase, ASCII, etc.

As noted above, the SAS accident data is in three separate subfiles, the first containing the basic accident information on a case-by-case basis, and then separate files containing information on vehicles and occupants in each accident case. The vehicle and occupant data can be linked to the basic accident data for specific cases using the accident case number. The accident subfile can be linked to the Roadlog file using three common variables – county, route number, and milepost.

Unlike an Accident file record that is referenced to a point on the roadway, each record on the Roadlog file contains information on a homogenous section of the roadway (i.e. a stretch of road which is consistent in terms of certain characteristics), with each new section being defined by a new beginning reference point. Each record on this Roadlog file contains current characteristics of the road system including surface type and width, shoulder and median information, lane information, etc. Information on curves and grades is captured in separate curve and grade files. The Curve File has data on all horizontal curves while the Grade File has information on grades greater than 3 percent. For curves having a degree of curvature greater than 90 degrees, Ohio designates them as “angle points” and that data is captured in a separate Angle Point File. Ohio doesn’t maintain a separate intersection inventory file. However, a “Points” file is available that contains point descriptors for a number of items including at-grade intersections, overpasses, underpasses, bridges etc. Details of these accident and roadlog files are presented in the following section.

Details of Major Files

The Accident Files

Prior to mid-2011, an accident was reported if it involved a personal injury or total property damage of $400 or more. However, in some cases crashes with damages below $400 were also recorded on accident report forms. Ohio increased the reporting threshold from $400 to $1,000 on 09/07/2011. The Ohio State Highway Patrol (SHP) and the local sheriff’s offices do most of the crash reporting in Ohio. Ohio doesn’t include accidents reported by citizens in their system. All police reports statewide are sent to the Ohio Department of Public Safety. Prior to 1997, the Department of Public safety was responsible for keypunching and location coding the accidents (after performing QC checks). After 1997, this task was outsourced to private contractors. (Note that 1997 is the first year of Ohio data in the HSIS system.)

All agencies across Ohio use the same accident report form to report accidents. A new form with major changes was introduced in 2000. In addition to this, as noted above, the State Highway Patrol began to outsource the data coding to private contractors in 1997.

Approximately 137,000 crashes occur in Ohio statewide each year. The HSIS data set contains a subset of these accidents that occurred on the state-inventoried system. This data set includes approximately 150,000 accidents per year, approximately 270,000 vehicles per year and approximately 326,604 occupants per year. Police officers reporting accident locate them within 0.01 miles of a given milepost. There are physical mileposts available on all rural state routes and some county routes, and on Interstates in all incorporated areas. It is estimated that about 10% of the accidents in the accident subfiles cannot be matched to segments on the roadlog file. Ohio DOT suspects outsourcing of the location coding to be the main reason for this. Since the majority of the HSIS analyses involve linkage with roadway data, a decision was made to delete these accidents from the accident subfiles. This results in approximately a 10 percent reduction in the total number of accidents (and vehicle and occupants) in the files.

In general, Ohio accident files capture information on all relevant variables. Our discussions with Ohio DOT staff revealed that they think the police make some errors in coding the angle, left turn, and head on crashes at intersections. They expect the new accident report forms being used in 2000 and later correct this shortcoming since it provides a sequence of events and pre-crash maneuvers/directions. Also, due to the change in accident report form in 2000, a number of variables has been changed or added in the Ohio accident files in subsequent years.

Approximately 75 percent of the accidents on the linkable file are property damage only and less than 0.5 percent is fatal accidents. Approximately 70 percent vehicles are multi-vehicle in nature, while the remaining 30 percent are single-vehicle accidents of one type or the other.

An assessment of the completeness and accuracy of the data is based on conversations with OH staff and a series of single-variable tabulations run each year for key analysis variables. These quality-control runs allow the HSIS staff to examine both the percent uncoded for each variable and changes across time in the individual codes within each key variable. These yearly runs are performed on all formatted variables. These runs have consistently indicated that almost all of the variables in the three subfiles have very few uncoded and very few error codes. Where high numbers of uncoded cases or inconsistencies in codes are found, a “NOTE” has been included under the pertinent variable in the later SAS format sections.

In addition to the quality-control checks noted above, in order to further check the accuracy of some of the accident variables, a series of comparisons were made of variables that should have been somewhat similar on the accident subfiles according to their definitions (both within the same subfiles and across subfiles). For example, NUMPEDS variable is populated largely only when ACCTYPE is pedestrian. Again, if there are any cases in which variables are either less than totally consistent with other variables or have changed across time, a “NOTE” will be included in the SAS formats section that follows.

The Roadway Inventory Files

The Ohio roadway inventory files contain current characteristics of the state road system for each year. These data are divided into five files within the HSIS system. The first is the basic roadway characteristics file (i.e. the “Roadlog”) containing information on the roadway mainline cross-section. The second is a Curve File, which contains information on each horizontal curve on any inventoried segments (except for curves of degree greater than 90 – see below). The third is the Grade File, which contains information on each vertical grade that is greater than 3 percent. Fourth is the Angle Points File, which has information on those curves that have a degree of curvature greater than 90 degrees. And fifth is the Points File, which contains point descriptors for a number of items such as at-grade intersections, railroad grade-crossings, etc. Ohio provides the curve and grade information in a single inventory file named “State Supplemental Inventory.” HSIS staff processes this inventory file and creates three separate files -- the curve file, the grade file and the angle point file. All the roadway inventory files are developed by the ODOT staff based on as-built plans. Updates on the file are done based on the respective project plans. In general the ODOT Roadway inventory office feels that the data is quite accurate.

The Roadlog File

The ODOT Roadway Inventory section of the Office of Technical services is responsible for maintaining inventory of all public highway in Ohio, about 116,000 miles in total. Of these, there is detailed inventory information on approximately 19,500 miles of roadway, which is captured by HSIS and is shown in Table 1 below. This includes all functional classes of roads within the state system – Freeways, Arterials and collector, both rural and urban. This file contains information on approximately 1,500 miles of Interstates, 4,000 miles of U.S. Routes and 14,000 miles of State Routes. Currently there are nine roadlog inventory files in the HSIS system, 1997 – 2011. Because a new record is generated each time any of the items in the file changes, the sections that are generated are fairly short, resulting in a large number of individual records. The approximately 19,500 miles of inventory information is divided into approximately 32,000 records, resulting in an average section length of 0.61 miles.

The state maintained portion of the file is basically updated daily based on construction and maintenance plans and input from the local division engineers. Data changes are extracted from these plans and are activated in the system on the date that the project has been completed. An "effective date" is placed on the file at that time to indicate that one or more of the variables for that roadway section have been changed.

The file contains general cross section information related to travel way widths (indicated by surface widths and roadway widths), number of lanes, median width and other variables. All standard cross-section variables appear to be present except for individual measures of shoulder width (paved and unpaved) and shoulder type for each side (inside and outside) of the roadway in the 1997-2000 data. For these years, the total shoulder width for both sides can be calculated based on “Surface Width” and “Roadway Width” but not distributed to each side. From 2001 onwards, new variables are added that give inside and outside shoulder widths. Thus it is important to note here that the shoulder width variables available in the HSIS file are not populated for 1997 – 2000 data.

It is noted that in some cases, OH data has two different variables providing the same information. For example, surface type is described by the two different variables SURF_TYP and SRF_TYPF. This is because OH collects some additional variables that are required by FHWA for HPMS reporting or other purposes. Data analysis by HSIS staff and conversations with ODOT staff revealed that in general, where two variables explain the same characteristic, the non-FHWA required variable is more detailed and reliable due to the updating system. The only exception is for “access control,” where ODOT recommended the use of the FHWA variable. Appropriate notes are provided under each of these variables in the formats section that follows.

Unlike most states, OH data contains both the standard location variables -- County / Route / Beginning and Ending Mileposts -- and a link/node linear referencing system for each segment. However, since the crashes do not have link/node indicators, county/route/milepost is still used to locate the crashes on an individual roadway segment. The link/node referencing system allows the state to track and update information easily and accurately.

Traffic information in the form of Average Daily Traffic is included for each section on the file. This information is covered by three variables -- total AADT, AADT for passenger cars and trucks type A; and AADT for truck types B and C. A detailed description of the traffic count procedures in included below in the section “Traffic Monitoring Procedures.”

Two new variables, RODWYCLS and MVMT, have been created by HSIS staff in the roadway segment file of each of the HSIS states. The RODWYCLS (Roadway Class) variable is based on the combination of rural/urban, access control, number of lanes and median type variables. This variable classifies each roadway segment into one of ten roadway types described in the later “Format” section. This variable is also included as an accident-file variable by matching each crash to its corresponding roadway segment. The MVMT variable (Million Vehicle Miles of Travel) is calculated for each segment in the roadway file by multiplying the segment length, AADT and 365 days in a year, and dividing by one million. Both these variables were created in response to inquiries from data users, whose most frequent questions have concerned either crash frequencies or rates (per MVMT) for one or more of these roadway classes.

To assess the accuracy of roadway inventory variables in this roadlog file and the related files concerning points, curves and grades, we questioned the ODOT staff and examined a series of single-variable tables for key variables in each of the files. The ODOT staff feels that the overall quality of the variables in all the three files is very high. It should be noted that the data developed by ODOT is based on as-built plans and is updated systematically each year. Project plans are used for these updates. In addition, a field person in each highway district completes a “field sheet” to verify changes in the system each year and these are sent to the Roadway Inventory group for use in the computer file updates. This is a more extensive update system than in most HSIS states.

In addition to information received from ODOT staff, single-variable tabulations were run to examine the questions of reporting completeness and data accuracy. Here, study of percentage of “unknown”, “not applicable” and “not stated” values for more than 30 key variables in the Roadlog file indicate that, in general, the data are coded to a high degree of completeness. For most variables, there were no missing data. The data also appear to be quite consistent across years, and similar variables appear to have similar values. We also attempted to determine if there was consistency between pairs of similar variables found in the Inventory File. In general, there was. For example, the total mileage for divided highways appeared to be consistent with total mileage for segments having a valid median width. Notes are included for those few variables that were found to be inconsistent in the format section of the guidebook.

The Curve File

In general, based on both the interviews and the data comparisons conducted, the data are felt to be quite accurate. In the limited number of cases where possible inaccuracies or missing values were found or where more detailed definitions might be critical in future analyses, notes are included under the specific variables in the later format section.

As noted above, Ohio has been providing curve data to HSIS since 1997. However, beginning in or around 2009, Ohio staff stopped the systematic updating of the curve data. They are attempting to develop a new GIS-based curve-update method, but that has not been completed. Ohio DOT and HSIS staffs agree that the 2009 curve file in HSIS should be accurate enough for use with at least the 2010 roadway information due to the fact that there are only a limited number of changes to curves in any given year. The decision of whether or not to use the 2009 data in analyses using post-2010 data will be left up to the user. The following narrative describes the 1997-2009 curve data.

The Curve File contains information on all horizontal curves present on the 19,500 miles of inventoried data present in the roadlog file. The total length of all curves present in this file is about 1,120 miles, which is captured by approximately 18,500 records, resulting in an average curve length of approximately 0.06 miles. The file currently contains information on curve length, degree of curve and direction of curve. The inventory group is currently examining the possibility of collecting ball-bank data for future inclusion. A segment on this file can be located using the begin milepost, end milepost, county, route number and station equation information – similar to the roadlog file. Again, as-built plans are used to create this file and project plans to update information, similar to what is followed for all the five roadway inventory files. Our discussions with Ohio staff indicated that, though the quality of data may be slightly inferior compared to the cross-section data, it is free of any major shortcomings.

The Grade File

As with the curve file, systematic updating of the grade data stopped in or around 2009. See the discussion in the preceding section. The following narrative describes the 1997-2009 grade data.

The Grade File has information on all vertical grades greater than 3 percent. Total length of all grades present in this file is about 2,340 miles, which is captured by approximately 20,000 records, resulting in an average grade length of approximately 0.11 miles. The file currently contains information on the grade length, direction of grade and percent of grade. This file can be linked to the other files using the same location variables – county, route number, begin milepost, end milepost and station equation. Since the curve file and grade file are developed from the same inventory, the way in which these files are created and updated and the data quality are similar.

The Angle Points File

Sharp horizontal curves having degree of curvature greater than 90 degrees are designated by ODOT as “angle points”. All variables and the manner in which the file is developed remain similar to that of the Curve File. While even these sharp curves would have some curve length in reality, the segment length in this file is set to zero for all the records.

The Points File

Ohio doesn’t have a computerized intersection inventory file but has a “Points” file that contains point descriptors for a number of features including at-grade intersections, overpasses, underpasses, bridges, railroad crossings etc. (Note that Ohio is building a detailed intersection file that should be available around 2015.) The file has approximately 58,000 intersections, 4,500 interchanges, 5,000 bridges and 1,800 railroad crossings.

For intersections and interchanges, the file contains a mainline milepost for all state-system crossing routes (i.e., all intersections or interchanges where an Interstate, State Route or U. S. Route crosses an Interstate, State Route or U. S. Route), and a mainline milepost for many intersections where a state-system road intersects with a county or local road or street. ODOT staff is continually updating the file by adding additional intersections with city or county crossing roads, but the file cannot be yet considered a census of all intersections. For all intersection of two state-system roads, there is location information for both the mainline and the crossing route, which makes it possible to link to roadlog inventory information (and accident information) on both intersecting routes. There is no information on signalization, channelization, type of intersections/interchanges etc. Ohio is making efforts to include this information in the future. There are approximately 200 interstate-to- interstate junctions, 6,000 state-to-state and 900 US route-to-US route intersections. Like all other roadway inventory file, this file has been developed from as-built plans and updated based on project plans.

The Intersection File

(NOTE: This file will not be ready for distribution by HSIS until mid-2015.)

In the 2010 – 2011 period, Ohio DOT staff began development of an intersection file for use with FHWA’s SafetyAnalyst software. The file is expected to be completed in mid-2015 and will become part of HSIS at that time. It contains information on approximately 47,500 intersections – all intersections on state-system roads (i.e., Interstates, US routes and State routes) where the minor (crossing) route is either another state-system route or a county, township or municipal route. Intersections with lower-volume urban streets and commercial driveways are not included. The data are separated into two separate files – a General Intersection File and a Legs File. The General Intersection Subfile contains various descriptors of the intersection location and crossing routes, type of intersection, traffic control, urban/rural setting, whether the crossing roads are offset or not, and a unique intersection identification number than can be used to link to each leg. In addition, the General Intersection Subfile includes AADTs (and AADT years) for both the major and minor roads for 1995-present. Not all years would have an AADT estimate for any given intersection.

The Legs subfile, as the name implies, describes each of the intersection approach legs. Each leg or approach record contains variables related to the direction of approach; the number of thru, exclusive left turn and exclusive right turn lanes on the approach; left-turn phasing; speed limit; one way/two way, and turn prohibitions on the leg.

The intersections were identified from the road inventory file (line breaks in the Linear Reference system). The inventory data were extracted from video images collected for Ohio’s 2009 and 2010 video log file. Inventory data was also extracted from Google Street View images if the video log images were not present or not sufficient. DOT staff feels that the data are sufficiently accurate for use in safety analyses due to the care taken in the data collection process.

It is noted that in the original version of the file, AADT information is present for two routes – a “major road” and a “minor road.” If there are more than two crossing routes (e.g., a five-leg intersection), no AADT data is available for the additional leg. The “major road” is the highest priority route based on route type – Interstate, then US and then State Route. The “minor road” will then be the road with the second highest priority. MN staff is exploring the possibility of adding AADT information from additional legs in the future.

Traffic Monitoring Procedures

The Traffic Monitoring Section of the Office of Technical Services is in charge of collecting traffic counts information. This information is covered by three variables – total AADT, AADT for passenger vehicles, and AADT for medium and large trucks. These data are based on a combination of permanent counters that count traffic 24-hours each day for 365 days each year and a series of short-term counts conducted each year. Ohio has 180 automatic traffic recorders (ATRs) recording 24- hour, full-year data. Vehicle class / length data is collected at 136 stations and weigh-in-motion collected at 37 stations. These data are used to develop seasonal and daily adjustment factors for the 27,600 short counts that are done on a three- year cycle. Each short count is for 24-48 hours. Ohio attempts to collect vehicle classification data during these short counts also. At times, only volume data is collected and the 48-hour period is shortened. In some cases only the number of axle impulses is counted. The ODOT utilizes consultants to collect data for the short term count program.

To convert the short-term coverage counts to AADT, Ohio applies adjustments for seasonal differences in the daily traffic. For seasonal corrections, each coverage count location is assigned to one of the functional classes where permanent counters are located. The seasonal factors are based on averages from all ATRs in that group. Thus Ohio adjusts short-term counts to AADT using seasonal adjustment factors for each functional class.

When a road section is not counted during a given year, annual adjustment factors are developed and applied to the most recent prior year’s count. Ohio develops two types of annual adjustment factors – one that can be applied from year to year and second that is a cumulative adjustment factor that can be applied from any given year to the current year. Average growth factors are created each year for each functional class of roadway using ATR data and data from short counts for the current year. The adjustment factor applied to a particular uncounted section is based on its functional class. Ramp balancing is frequently used to calculate mainline limited access roadway segment volumes. This procedure is necessary because collecting data on mainline interstate segments is unsafe for crews due to the high volumes of traffic on Ohio’s interstate roadways.

As noted earlier, some of the short AADT counts measure only the number of axles passing a particular location. To adjust that to the actual volume at that location, axle correction factors are applied. Axle correction factors are calculated by combining data from Automatic Traffic Recorders (ATR’s) and 48-hour vehicle classification counts. An average axle correction factor is calculated for each functional classification of highway. These factors are obtained by computing the total number of axles crossing a point and dividing that by the total number of vehicles. These factors are then applied to those short term AADT counts which collect only the number of axles to get a count of the number of vehicles passing that section.

ODOT’s count program has expanded significantly over the last 10 years. In addition to increasing the number of data collection stations across the state, we have incorporated automated software programs to help us process and report the data. ODOT is very confident that we produce quality traffic monitoring data.

Issue Related to Merging of Files

As noted above, the accident data are subdivided into three subfiles – accident, vehicle and occupant. The Accident and Vehicle Subfiles can be linked together using the accident report number (i.e., CASENO). When linking the occupant subfile, the additional linking variable related to vehicle number (i.e., VEHNO) must match so that the occupants are associated with the vehicle in which they were traveling. To link vehicles with accidents, first sort both subfiles by CASENO. To link the Occupant file with the other two subfiles, first sort both the Vehicle subfile and Occupant subfile by case number and vehicle number. Next sort the Accident subfile by case number. Alternatively, the separate subfiles can be linked by specifying as SQL JOIN operation with the constraining condition that case number and vehicle number from each table are equal. SQL processing does not require the data to be pre-sorted and the output will not be in any particular sort order unless ORDER BY is specified.

The Accident Subfile can be linked to the Roadlog File using the CNTYRTE and MILEPOST variables in the crash record, and the CNTY_RTE, BEGMP and ENDMP variables in the Roadlog File. (Note that the “station equation” is included as part of county-route in the HSIS variables.) Similarly, the accident subfiles can be linked to Curve, Grade, and Angle Points using similar variables found in each respective file. To link the Accident File and the Points File, CNTYRTE and MILEPOST variables from the Accident file are matched with CNTY_RTE and MILEPOST variables of the Points File. To extract data on the intersecting (crossing) state-system route in the Points File, the Roadlog File can be linked to the XMILEPST and XCNTYRTE variables.

To prepare the Accident Subfile for linking with the Roadlog File using a SAS data step process, the analyst must sort both the Accident and the Roadway File into location order by CNTYRTE and MILEPOST on the Accident file and by CNTY_RTE and BEGMP on the roadlog file. Similar sorts would be done with other files to be merged. For the alternative SQL join, the analyst must specify an exact match on CNTYRTE and a range match where MILEPOST occurs between BEGMP and ENDMP. (Programs to accomplish this merging and division are available from HSIS staff at FHWA).

Finally, where appropriate and possible, a format that defines categories within a given variable has been developed for HSIS SAS variables. These categories are shown in the pages below. If you are an SAS user and wish to receive a formatting program that includes these SAS formats (with linkage to the pertinent variable name), please request these from the HSIS staff who provide the data file to you.
