Itr*ekma 1.6. Uama The objective of this effort was to determine the feasibility of a study to provide statistically sound estimates of the accident rates of longer combination vehicles currently operated in several of the Western states under special permit. In order to evaluate the feasibility of such a study, information on the types of longer combination vehicles allowed, number of permits issued, and accident data available was obtained from the 12 Western states that allow one or more of the longer combination vehicle types. The available information indicated that perhaps as many as 40,000 longer combination vehicles are permitted in the 12-state region. However, the available accident data identified about 500-600 accidents in 1986, only one-tenth the expected number. Given the uncertainty about the accident reporting, a pilot study in the state that appears to have the best accident reporting, Washington, is described. Separate surveys of accidents and travel would be conducted over a one-year study period. 17. Key Wwda 18. Diatribtion Statrant Longer combination vehicles Unlimited 19. S.arri9 CImuf.

For purposes of this study, the longer combination vehicles of interest are Turnpike Doubles, Rocky Mountain Doubles, and Triples. The current permits impose certain restraints on the operation of these vehicles. There is interest in these vehicles because they provide an opportunity for improved productivity in some situations. However, there is concern about the safety of these vehicles due to their greater length and configuration. In general, the constraints imposed by the permits are intended to compensate for these safety concerns. The objective of this study is to determine the feasibility of collecting accident and travel data that would permit accurate estimates of the accident rates of these longer combination vehicles under the current operating conditions. For the purposes of this study it is assumed that a Rocky Mountain Double (RMD) is typically a 40-45 foot semitrailer with a 28-foot pup trailer. A Turnpike Double (TPD) is twin 42-45 foot trailers and a Triple is three trailers of approximately equal length. In order to determine the feasibility of such a study, it is necessary to have information on the nature and extent of longer combination vehicle (LCV) use in the Western states and whether certain key information could be provided for an in-depth follow-up study. The key information includes maximum weight and length limits, permits issued, and accidents. It was also necessary to determine if longer combination vehicles could be identified from the general truck population, and if we could be notified and provided with a police report when a longer combination vehicle was involved in an accident. Thus, the first task was to contact the 17 contiguous Western states in order to assemble as much of this information as was available. States contacted included: Arizona, California, Colorado, Idaho, Kansas, Montana, Nebraska, Nevada, New Mexico, North Dakota, Oklahoma, Oregon, South Dakota, Texas, Utah, Washington, and Wyoming. The results of this effort are described in Section 3, Overview of Current LCV Operations. Much of the supporting material is appended. The study design issues are discussed in Section 4. These issues include the influence of operating restrictions on the accident experience of longer combination vehicles and the problems of comparing existing longer combination vehicle experience with other configurations not subject to the same restrictions, sampling frame issues associated with determining the exposure of longer combination vehicles, survey methods for accident and exposure data, analysis methods, and possible study designs and costs. The findings of this feasibility study are summarized in the next section. Twelve of the Western states contacted allow longer combination vehicles: Colorado, Idaho, Kansas, Montana, Nevada, North Dakota, Oklahoma, Oregon, South Dakota, Utah, Washington, and Wyoming. The information available from those states indicates that about 40,000 annual permits have been issued plus about 60,000 single-trip permits. These figures tend to substantiate extensive use of these vehicles. The available accident data identify only 500-600 longer combination vehicles involved in police-reported accidents in 1986. This figure is much lower than would be expected based on the overall accident experience of combination vehicles in the United States. This situation may result from an over-estimation of use, accident rates appreciably lower that the national average due in part to the operating restrictions on these vehicles, or under-reporting of the accident experience. In any event, accident reporting is the critical element of the study design. A pilot study is proposed in the state of Washington, in part because this state reports the highest accident experience of any of the states contacted even though some appear to issue many more permits. Unlike the IIHS case-control study in Washington, this study would measure accident rates as accidents per vehicle mile traveled rather than as the odds ratio of accident involvement at the accident sites. Accident rates are preferrable because they quantify the system-wide risk, and provide the ability to distinguish the role of the roadway from that of the vehicle. Only the Rocky Mountain Double is permitted in Washington, simplifying the analysis and sample size requirements. Operation is allowed in Washington on an extensive network of about 6,700 miles of interstate and state highways. This study would allow one to isolate the experience of Rocky Mountain Doubles off the interstate roads, an issue of some interest. The pilot study period would be one year. At that time a decision could be made to end the study, continue for another year, or expand to other states. Overview of Current LCV Operations The 17 contiguous Western states were contacted for information on the operation of longer combination vehicles, including any operational constraints, permit or registration procedures, available records on longer combination vehicle permits and registrations, identification of longer combination vehicles on accident reports, and availability of accident reports, Twelve of the states (Colorado, Idaho, Kansas, Montana, Nevada, North Dakota, Oklahoma, Oregon, South Dakota, Utah, Washington and Wyoming) do allow longer combination vehicles and would agree to cooperate with a study by sending police reports on longer combination vehicle accidents. Not all states code or keep records in the same manner. For the states that just code "doubles" it will be necessary to look at each police report and determine if the combination involved qualifies as a longer combination vehicle. The information provided by the states is summarized here in three areas: longer combination vehicle limits, permits, and accidents. The information on limits focuses on the specific longer combination vehicle configurations allowed and pertinent allowable lengths, weights, and o erating restrictions. The information on permits focuses on the availag le information that would identify longer combination vehicles operating in each state. This information is needed to develop a sampling plan for an exposure survey to determine longer combination vehicle travel. The accident information includes the available information on the number of accidents involving a longer combination vehicle, the ability to identify longer combination vehicle accidents, and the availability of the accident information. What follows is a presentation of information provided by the states as of May 1, 1988. A state by state summary is included at the end of this

  • Directory of Thruway Exits Community Listing
    DIRECTORY OF EXITS Community Listing TAP-304 (5/06) The New York State Thruway Directory of Exits The Directory of Exits has been developed to provide another level of service to Thruway customers, suggesting exits for reaching various communities across New York State via the New York State Thruway. It is designed for use by motorists while on the Thruway, and in conjunction with the New York Thruway Map & Travel Guide and other detailed highway maps. This Directory does not include all cities, villages, towns and hamlets within New York State. In most cases, the Directory shows exits on portions of the Thruway closest to the listed community. Emphasis is, however, on superhighway links, which provide safe, swift means of travel. Other exits may take you to routes that are shorter or more scenic. If you find you are traveling between the exits listed, consult your map for an exit connecting with a more convenient route. When using any driving directions or map, it is a good idea to watch out for construction and follow all traffic safety precautions. The Directory of Exits should only to be used as an aid in planning your route. Before you head out on the road, plan your entire route from start to finish. Knowing how to get to your destination will help ensure a safe trip. For a complimentary copy of the New York Thruway Map & Travel Guide, please contact the Public Information Office at (518) 436-2983.
