FIVE PERCENT REPORT
August 2007
1. Introduction
Pursuant to Federal Highway Administration guidance "Highway Safety Improvement Program, 23 U.S.C. 148 (c) (1) (1) Five Percent Report" of April 5, 2006, the Montana Department of Transportation (MDT) presents the following information:
Montana has over 70,000 miles of roads, spread over 145,000 square miles. Montana is larger than the combined area of the 10 North-Atlantic States of Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, New Jersey, Connecticut, New York, Maryland and Delaware. Its estimated 2005 population is just over 935,000 inhabitants. This population represents only 2 percent of the combined population of those 10 North-Atlantic States. The 2006 Montana Highway Patrol records show 22,246 crashes and 263 highway fatalities. In 2006, the 10 North-Atlantic States had 4,241 highway fatalities according to the Fatal Analysis Reporting System. The 2006 average number of crashes on the rural off-system roads was 6 crashes per 100 miles, compared to 212 crashes per 100 miles on the rural Interstates.
Director Jim Lynch approved the Comprehensive Highway Safety Plan on September 20, 2006. Highway safety does not involve just the Department of Transportation. Numerous agencies, Tribal governments and advocacy groups are involved. At the Federal level, the main agencies are the Federal Highway Administration, the National Highway Traffic Safety Administration and the Federal Motor Carrier Safety Administration. At the State level, the main partners, besides MDT, are the Department of Justice with the Montana Highway Patrol and the Motor Vehicle Division, the Department of Public Health & Human Services and the Office of Public Instruction. At the local level, Police and Sheriff Departments, Public Works/Road Departments, emergency medical services and the courts dealing with traffic issues participate in highway safety. In short, highway safety involves everyone. These stakeholders have selected the following focus areas:
- Increase safety belt usage;
- Reduce statewide alcohol-and drug-impaired fatal and incapacitating injury crashes;
- Reduce Native American fatal crashes;
- Reduce and mitigate the consequences of single vehicle run-off-the-road fatal and incapacitating injury crashes;
- Develop and implement a comprehensive, coordinated transportation records and crash reporting, data management, and analysis system, accessible to all stakeholders, to manage and evaluate transportation safety;
- Reduce young driver (under age 21) fatal and incapacitating injury crashes;
- Establish a process to reduce crashes, injury crashes and fatal crashes in identified high crash corridors and locations;
- Reduce fatal and incapacitating injury crashes involving trucks, and
- Develop an effective and integrated Emergency Medical Services (EMS) delivery system.
In addition to these nine priority emphasis areas, Montana adopted three additional emphasis areas:
- Reduce fatal and incapacitating injury crashes in urban areas;
- Reduce motorcycle fatal and incapacitating injury crashes, and
- Reduce older driver (age 65 and over) fatal and incapacitating injury crashes.
Based on the Comprehensive Highway Safety Plan, the Highway Traffic Safety Bureau developed the 2007
Highway Safety Plan, (www.mdt.mt.gov/publications/docs/brochures/safety/safety_plan.pdf) following the directions from the National Highway Traffic Safety Administration (NHTSA). The Motor Carrier Services Division wrote the 2006 Motor Carrier Safety Plan and is working on the 2007 Plan under the guidance of the Motor Carrier Safety Administration. For the Highway Safety Improvement Program and the Railroad Safety Programs a list of projects is developed yearly. MDT, with a Consultant, is reviewing its safety business processes involving the NHTSA safety programs, the Motor Carrier Safety Plan, the Highway Safety Improvement Program, the Railroad Safety Programs and other safety activities. The goals of this review are to make the process more efficient, coordinate safety efforts and create one unified approach to the State's highway safety programs.
2. Data
Crash data are centralized with the Montana Highway Patrol. All the 2006 data have been entered in the data base. Not all crashes occurring on Indian Reservations are reported and occasionally a low population city does not send their crash investigator's reports to the Highway Patrol. Most of the first quarter 2007 crash data are available as of July 31, 2007. Montana uses several crash referencing systems: route and distance from mile markers, link/node system, range, township and section for rural off-system roads, route and distance from a node or nearest landmark. The Montana Highway Patrol is in the process of implementing Global Positioning System (GPS) for locating crashes. The Montana Department of Transportation is correlating the route mile posting to the GPS coordinates and incorporating off-system roads into its road log. A test for verifying the GPS accuracy is planned. The long range goal is to have all crashes referenced by GPS.
The traffic volumes on local roads are sparse. The 2006 vehicle miles traveled by roadway system were released at the end of July 2007. The Department changed its programs for traffic volume data collection and will provide data faster, once the system is fully implemented.
In late 2006, Montana created a Traffic Records Coordinating Committee overseeing all the traffic safety data from crash, roadway, traffic, enforcement, emergency medical services and court records. There are also continuing efforts to share crash information with the Indian Reservations.
3. Crash Trends and Performance Measures
Table 1 and Figure 1 give the number of fatalities and incapacitating injuries on Montana highways over the last ten years 1997-2006. The trend of fatalities and incapacitating injuries shows s reduction of 17 percent from 2,241 in 1996 to 1,870 in 2006. Table 2 and Figure 2 illustrate the percent of belted injured occupants in crashes from 1997 to 2006. The percentage of belted injured occupants shows an increase from 63.7 percent in 1996 to 73.6 in 2006, a 5 percent increase in the number of belted injured occupants. Table 3 and Figure 3 show the alcohol related fatalities as percent of all fatalities in the 1997-2005 period. Unfortunately the alcohol related fatalities in the 1996-2005 period remain a high percentage compared to all fatalities, fluctuating between 40 and 50 percent, with a 31 percent increase in the number of alcohol related fatalities between 1996 and 2005. The Statewide crash rate was estimated at 2.64 crashes per million vehicle miles traveled in 1996 and 2.01 in 2005, as documented in Table 4 and Figure 4.
4. High Crash Corridors and Spot Improvements
In line with the Comprehensive Highway Safety Plan, Montana identified the high crash corridors in terms of corridors with high crash severity, the corridors with high number of unbelted vehicle occupants involved in severe crashes and corridors with high incidents of drivers who had been using alcohol or drugs and who were involved in severe crashes. The mileage identified for these corridors represents over 5 percent of the 12,900 miles of National highways, State Highways and State maintained highways, carrying the highest traffic volumes and experiencing the highest numbers of severe crashes.
MDT identified corridors with a combination of high crash severity rate and high number of fatalities and incapacitating injuries per mile. The corridors with the highest severity rates using a 10 mile plus segment length ( 5 miles plus segments for State Secondary routes and the total length of the routes in urban areas) were identified as well as the corridors with the highest number of severe crashes (fatal and incapacitating injury crashes). MDT added the crash severity rate and the number of fatalities and incapacitating injuries per mile to derive the high severity corridors. The crash data for these corridors identified in 2003-2004 were updated with 2002-2006 crash data. The severity rate is defined as the number of crashes with a fatality or an incapacitating injury times eight plus the number of crashes with a non-incapacitating injury or possible injury times three plus the number of property damage only crashes per million vehicle-miles traveled.
Table 5 lists the corridors with highest ratings on the rural National Highways, rural State Primary and Secondary highways.
For the urban areas on the Interstate and on the combined National Highways and State Primary routes, the routes with the highest combination severity rate and high number of fatalities and incapacitating injuries per mile are also listed in Table 5.
These corridors are located on the attached map in blue.
MDT has established a draft process to perform safety reviews of these corridors. Corridor safety reviews are planned in 2007-2008. The intent is to develop low cost safety improvements as the engineering component of this process and pursue strategies such as enforcement activities and public education, involving the disciplines of the participants in the development of the strategic highway safety plan.
In addition the 10 plus mile on-system segments with the greatest number of severe crashes involving an occupant using no protective device are shown on the map in green. Table 6 lists these corridors. Another major problem in Montana is the alcohol and drug focus area. The map illustrates the 10 plus mile segments where the highest number of drivers, who had been using alcohol or drugs were involved in severe crashes. These corridors are depicted in red on the map and listed in Table 7. Selective enforcement will be concentrated in most of these corridors. Most of the education campaigns will be Statewide. Emergency Medical Services and Trauma Services Section provide intervention strategies with patients involved in alcohol/drug related crashes and have formed regional task forces promoting a reduction of trauma.
MDT provides the latest list of Highway Safety Improvement Program projects approved by the Transportation Commission in May 2007. These sites were selected based on high crash rates, high severity rates and high number of crashes. Sites were also submitted for evaluation by local agencies, enforcement agencies and MDT Districts. The 2007 approved projects with the highest benefit/cost ratios are distributed with the following percentages by highway classification systems:
| Interstate | 4% |
| National Highway Non-Interstate | 35% |
| State Primary | 22% |
| Urban | 13% |
Projects on collectors and local roads:
| State Secondary | 19% |
| Local roads | 7% |
The attached map shows the location of the sites where the proposed improvements exceed $50,000 with Table 8 summarizing the proposed improvements. These 19 sites represent 9 percent of the 209 sites identified through the crash concentration searches, enforcement crash review requests, Districts' and local requests for safety reviews. Table 9 summarizes the locations identified in the 2006 Five Percent Annual Report with a brief discussion of the project status and special impediments. Table 10 provides this information for the corridors.
The MDT highway program, that includes safety elements with each project, is compiled in the State Transportation Improvement Program (STIP), that can be viewed at www.mdt.mt.gov/publications/docs/stip/2007stip_final.pdf.
For the 2007-2009 period, the program gives the following break down:
| Construction/Reconstruction | $ 444.2 Million (58.2%) |
| Resurfacing | $ 146.2 Million (19.1%) |
| Rehabilitation/Widening | $ 40.0 Million (5.3%) |
| Bridge Replacement/Rehab | $ 76.6 Million (10.0%) |
| Spot Improvement/Safety | $ 36.2 Million (4.7%) |
| Miscellaneous | $ 20.1 Million (2.6%) |
All the partners involved in the Comprehensive Highway Safety Plan hope that all these efforts will further improve the safety on Montana Highways.
