Synthesis of Traffic Calming Techniques in Work Zones
Status: Complete
Description: Nationwide, over 1,000 fatalities and 40,000 injuries occur annually in work zones, which include both construction zones and areas where maintenance is performed. The majority (85%) of work zone accidents result from unsafe driver behavior, and vehicle speed is often a factor in work zone crashes. In order to address speed and driver behavior near work zones, roadway agencies have developed different traffic calming measures.
The objective of this research was to summarize the effectiveness of different traffic calming treatments for reducing speeds in work zones. This project
1. identified work zone traffic calming treatments for which information has not been well summarized,
2. identified state of the art and new technologies for work zone traffic calming, and
3. synthesized research related to items 1 and 2
