Book Description
"The purpose of this study was to determine current motorist compliance to RTOR regulations, develop and field test countermeasures for RTOR pedestrian accidents, and develop improved warrants and guidelines for prohibition of RTOR. Based on data from several U.S. cities, only 3.7 percent of all right-turning drivers violate no turn on red (NTOR) signs. However, of drivers with an opportunity to turn right on red, 20 percent violated the sign. At locations with RTOR allowed, 56.9 percent of motorists do not come to a complete stop before turning right on red. Based on conflict and violation data, 30 countermeasures were developed as possible treatments for RTOR-pedestrian accidents. Seven of these were field tested, including an offset stop bar, a red ball (symbolic) NTOR sign, a larger 30x36-in (75x90-cm) NTOR sign, a Look For Turning Vehicles pavement marking, a NTOR When Pedestrians Are Present sign, and an electronic variable message (blank-out) NTOR sign. Several promising applications for the devices were recommended. A critique was made of the current MUTCD guidelines on RTOR prohibition. Based on an analysis of conflicts at 199 intersection approaches, improved guidelines were recommended"--Technical report documentation page

Book Description
This guide is intended to provide information on how to identify safety and mobility needs for pedestrians with the roadway right-of-way. Useful for engineers, planners, safety professionals and decision-makers, the guide covers such topics as: the Walking Environment including sidewalks, curb ramps, crosswalks, roadway lighting and pedestrian over and under passes; Roadway Design including bicycle lanes, roadway narrowing, reducing the number of lanes, one-way/two-way streets, right-turn slip lanes and raised medians; Intersections with roundabouts, T-intersections and median barriers; and Traffic calming designs.

Book Description
The Energy Policy Act of 1992 required NHTSA to conduct a study of the safety impact of permitting right and left turns on red lights. The report presents a brief summary of the current status of State implementation of laws permitting right and left turns at red lights, a brief review of previous research, and the results of analyses of currently available data assessing the safety impact of permitting right turns on red.
Field Evaluation of Two Methods for Restricting Right Turn on Red to Promote Pedestrian Safety

Book Description
Right turn on red (RTOR) is permitted at most signalized intersections in the United States, primarily to reduce vehicle delays and fuel consumption. However, RTOR increases the risk of motor vehicle crashes and injuries, especially to pedestrians and in urban areas. To reduce the risk of pedestrian crashes at busy intersections, RTOR can be either entirely prohibited, prohibited during specified hours, or prohibited when pedestrians are present. The purpose of this study was to evaluate two methods for restricting RTOR at urban intersections -- traffic signs prohibiting RTOR during specified hours, and signs prohibiting RTOR when pedestrians are present. Fifteen intersections in Arlington, Virginia, where RTOR had previously been permitted at all times were randomly assigned into three groups -- control, no RTOR during specified hours, and no RTOR when pedestrians are present. Signs prohibiting RTOR during specified hours were very effective at increasing the percentage of drivers stopping at stop lines (from 21 to 40 percent), reducing the percentage of drivers turning right on red without stopping (from 32 to 13 percent), and reducing the number of pedestrians yielding to turning vehicles (from 17 to 7 percent). Signs giving drivers discretion to turn right on red based on whether pedestrians are present were not effective.

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.
