This book was released on 1989 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1987, the Secretary of Transportation and Public Safety created a task force to study the potential effects of raising the speed limit on rural interstate highways in Virginia. In its 1988 session, the Virginia General Assembly passed legislation to increase the speed limit on rural interstate highways to 65 mph for passenger vehicles, but the 55 mph limit was retained for buses and large trucks. After implementation of the higher speed limit on July 1, 1988, the Secretary reconvened the task force to design a study to determine the effects of the changed speed limit. The Virginia Transportation Research Council was again asked to serve a the staff for the task force. The preliminary data provided in this report represent only 5 months of experience with the 65 mph speed limit and are presented for information only. Any conclusions drawn from these data would be inappropriate and perhaps incorrect. After the speed limit for cars was increased by 10 mph, the average and 85th percentile speeds traveled by all vehicles on the rural interstate system increased by 3 mph, to 63 mph and 68 mph, respectively. The average and 85th percentile speeds traveled by trucks and buses, for which the speed limit remained at 55 mph, decreased slightly. Between July 1 and November 30, 1988, there were 44 fatalities in 35 fatal crashes on rural interstate highways in Virginia. This was a 76 percent increase over the 25 fatalities and a 52 percent increase over the 23 fatal crashes for the same time period in 1987. In the states that increased the speed limit, there was a 41 percent increase overall in the number of fatalities, but in states that did not increase the speed limit, there was a 54 percent increase in fatalities--higher than that noted for states that increased the speed limit. Many of the crashes that accounted for the increase in the number of fatal crashes on rural interstate highways occurred on I-81, and all of the multiple-fatality crashes occurred on either I-81 or I-95. In comparison with 1987, the number of fatal crashes in 1988 included 5 more involving vehicles that ran off the road, 4 more involving tractor trailers, and 3 more involving pedestrians. In October 1988, there was an abnormally high number of fatal crashes and fatalities on Virginia's rural interstate highways, but no patterns were found to explain this 1-month abnormality. Because there are not sufficient data to determine the reasons for the increases in fatal crashes and fatalities, data will be gathered over a 5- year period to determine the effect of the changed speed limit on Virginia's rural interstate highways.

This book was released on 1992 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: In April of 1987, Congress passed the Surface Transportation and Uniform Relocation Assistance Act (STURAA), which permitted states to raise their maximum speed limit on rural interstate highways (rural interstates) to 65 mph. Virginia's 65 mph speed limit went into effect July 1, 1988, for passenger vehicles and on July 1, 1989, for commercial buses. This report is the fourth in a series of reports to examine the 65 mph speed limit in Virginia and summarizes 30 months of experience with the 65 mph speed limit. Following the implementation of the 65 mph speed limit, average and 85th percentile speeds increased on Virginia's rural interstates, and fatal crashes and fatalities increased significantly. On Virginia's urban interstates, on which the speed limit remained at 55 mph, there was a smaller increase in average and 85th percentile speeds, but there was not a significant increase in fatal crashes or fatalities. National data show a substantial increase in rural interstate fatalities in states that increased the rural interstate speed limit to 65 mph and a decrease in states that maintained a 55 mph speed limit. The data in this report clearly show that speeds, fatal crashes, and fatalities increased on Virginia's rural interstates after the implementation of the 65 mph speed limit. However, these data do not reflect causation. It is possible that factors other than the change in the speed limit such as changes in traffic volumes, trip patterns, or trip purposes-are responsible for part or all of the increase in fatal crashes and fatalities. Causative issues will be addressed in the final report in this series, to be published in 1993.

This book was released on 1977 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report estimates the increase in the number of motor vehicle accidents, injuries and fatalities that would result from an increase in the national speed limit to 60 mph. The report makes use of available travel and accident statistics, adopts previously identified relationships between travel speeds and accidents, and relies on a stated set of assumptions. The major conclusion of the report is that raising the speed limit to 60 mph will result in an increase of approximately 3500 fatalities per year, thus offsetting most of the safety benefits experienced under the 55 mph speed limit. The report provides estimates for the year 1977, which was selected solely for the purpose of exercising the model. However, the same model can be utilized in a similar fashion to arrive at estimates for any future year for which both traffic and safety conditions can be forecasted.

Available in PDF, EPUB and Kindle. Book excerpt: The repeal of the National maximum Speed Limit law in 1995 enabled individual states to set their own speed limits. Speed limits are necessary to ensure mobility while preserving highway safety. It is important that states continually monitor and evaluate existing operating speeds in the context of changing patterns of travel, and changing characteristics of highways, vehicles, drivers, and land-use. Any efforts to review existing speed limits should be accompanied by evaluation of policy impacts such as safety and economic productivity. The goal of this research is to develop a set of speed limit policy guidelines for the state. The study reviews the historical trends in traffic speed in Indiana and recommends a detailed analysis of the impact of speed limit changes on safety and the trucking industry in Indiana. The report also presents a state-of-the-art practice review and a set of possible actions that may be considered for speed limits in Indiana.
