Abstract:

This document contains a series of Issue Briefs on various intersection safety-related topics. This is the Second Edition of these briefs. The target audience for the Issue Briefs consists of traffic engineers and transportation and safety professionals. Many products have developed over the past two years that will help practitioners evaluate causes of intersection crashes and potential solutions. The Issue Briefs provide practitioners with a substantial number of references and resources for subsequent review and consideration. The materials could also be used by a far wider audience of people and organizations who want to promote intersection safety issues within their area of influence. The topics included in this edition are as follows: (1) Introduction;(2) The National Intersection Safety Problem;(3) Traffic Control Devices: Uses and Misuses;(4) Stop Signs;(5) Signals;(6) Engineering Countermeasures to Reduce Red Light Running;(7) Red-Light Cameras;(8) Intersection Safety Countermeasures;(9) Pedestrian Safety;(10) Older Drivers;(11) ADA Considerations at Intersections;(12) Human Factors;(13) Access Management;(14) Roundabouts;(15) Road Safety Audits;(16) Work Zones;and (17) Resources. The format of the Issue Briefs has changed with the second edition. They are now three-hole punched and can easily be placed in a notebook for quick access and for reproduction as required.
