Book Description
Get a complete look into modern traffic engineering solutions Traffic Engineering Handbook, Seventh Edition is a newly revised text that builds upon the reputation as the go-to source of essential traffic engineering solutions that this book has maintained for the past 70 years. The updated content reflects changes in key industry standards, and shines a spotlight on the needs of all users, the design of context-sensitive roadways, and the development of more sustainable transportation solutions. Additionally, this resource features a new organizational structure that promotes a more functionally-driven, multimodal approach to planning, designing, and implementing transportation solutions. A branch of civil engineering, traffic engineering concerns the safe and efficient movement of people and goods along roadways. Traffic flow, road geometry, sidewalks, crosswalks, cycle facilities, shared lane markings, traffic signs, traffic lights, and more—all of these elements must be considered when designing public and private sector transportation solutions. Explore the fundamental concepts of traffic engineering as they relate to operation, design, and management Access updated content that reflects changes in key industry-leading resources, such as the Highway Capacity Manual (HCM), Manual on Uniform Traffic Control Devices (MUTCD), AASSHTO Policy on Geometric Design, Highway Safety Manual (HSM), and Americans with Disabilities Act Understand the current state of the traffic engineering field Leverage revised information that homes in on the key topics most relevant to traffic engineering in today's world, such as context-sensitive roadways and sustainable transportation solutions Traffic Engineering Handbook, Seventh Edition is an essential text for public and private sector transportation practitioners, transportation decision makers, public officials, and even upper-level undergraduate and graduate students who are studying transportation engineering.

Book Description
TRB's National Cooperative Highway Research Program (NCHRP) Report 672: Roundabouts: An Informational Guide - Second Edition explores the planning, design, construction, maintenance, and operation of roundabouts. The report also addresses issues that may be useful in helping to explain the trade-offs associated with roundabouts. This report updates the U.S. Federal Highway Administration's Roundabouts: An Informational Guide, based on experience gained in the United States since that guide was published in 2000.

The Impact of General Permissive Right and Left Turn on Red Legislation in Virginia

Book Description
Right turn on red (RTOR) maneuvers have been permitted at signalized intersections in Virginia since 1972. However, until January 1, 1977, following a study requested by the General Assembly, the maneuver was restricted to intersections at which a sign was posted to inform the motorist that RTOR was permitted. Under the pre-1977 legislation RTOR was allowed at only 8% of the state's intersection approaches. Under the legislation that became effective in 1977, motorists are allowed to make right turns on red and left turns on red from a one-way street onto a one-way street, unless the maneuvers are specifically prohibited by a sign. The purpose of the investigation reported here was to examine the benefits and problems resulting from the new legislation. The scope of the study included questionnaire surveys of the state's law enforcement and traffic officials; a telephone survey of public opinion; an accident analysis at 18 intersections; and field investigations at 48 sites to examine time and energy savings, operational problems, and driver acceptance of and compliance with the laws. The analysis of the study data revealed that the new legislation was working very well and was being enthusiastically supported by the vast majority of Virginia officials and the public. RTOR was permitted at 84% of the state's signalized intersection approaches and LTOR at 73% of the approaches where one-way streets intersected. Driver utilization of turn on red opportunities was found to be higher than had been reported in other states. Benefits in terms of energy savings during 1977 were estimated to be 3.6 million gallons of fuel for RTOR and 2,370 gallons for LTOR. A statewide surveillance indicated that 75 accidents involving RTOR motorists and 3 crashes related to LTOR had occurred in 1977. The majority of collisions had involved only minor property damage. It was found that to encourage uniform implementation of the new legislation there was a need for traffic officials to review all approaches at which turns on red were being prohibited to determine if the prohibition was necessary based on the standards promulgated by the Federal Highway Administration. Selective enforcement, supplemented with local media publicity, was recommended to encourage drivers to come to a full stop before turning on red. Because the benefits of the legislation far outweighed its disadvantages, no changes in the law were recommended.
Right Turn on Red

Book Description
The Commonwealth of Virginia implemented the sign permissive or "eastern" rule permitting right turns on red traffic signals where designated by sign in 1972. In 1975, as a result of the growing national trend toward employing the general permissive or "western" rule (right turn on red permitted except where prohibited by sign) and in the interests of motor fuel economy, the Virginia General Assembly directed the Department of Highways and Transportation and the Highway Safety Division to study right turn on red (RTOR) to determine whether Virginia's sign permissive law "should be retained, rescinded, or amended." The scope of this study included a survey of the literature, a survey questionnaire of Virginia traffic engineers, a telephone survey of traffic engineers in other states, field studies of vehicle delay times and traffic conflicts at 20 selected intersections in Virginia and North Carolina, and an analysis of traffic crashes at 20 intersections in Virginia before and after RTOR was permitted. The results of this study reveal that right turn on red signals can enable motorists to effect substantial savings in time and concomitant savings in gasoline by reducing the vehicle idling time at intersections. The average saving for right turning delayed vehicles was found to be 14 seconds. Since the general permissive rule for RTOR allows the maneuver at a greater percentage of approach legs than does the sign permissive rule, time and energy savings have been estimated to be greater statewide under the general permissive rule. Estimated savings in gasoline under the general permissive rule would be over three million gallons annually. No significant increase in traffic crashes was found in Virginia and no increase would be expected with the general permissive rule, as none has been experienced in any other state with either the general permissive or the sign permissive rule. Moreover, study data reveal that traffic conflicts and thereby crash potential are actually reduced under RTOR, and that crashes which do occur because of RTOR are generally not severe. When the total impact of RTOR was considered, the evidence was found to support the recommendation that Virginia implement the general permissive rule for right turn on red.
