Speed limits are a popular safety measure used in urban areas. A new analysis that monitored driving speeds before and after posted changes to speed limits reveals lower speed limits may not, at least initially, cause drivers to slow down.

Increasing Support for Innovative Traffic Solutions
When a transportation innovation shows potential for significantly increasing safety, implementation may seem like the obvious next step. But without public support, a project can be met with resistance that results in delays, additional costs and a lost opportunity to save lives.

Impacts of Lane Conversions on Level of Service
Reconfiguring roadways, also referred to as a “road diet,ˮ can be a low-cost safety solution that makes space for different travel modes in addition to motor vehicle traffic. New guidance gives local engineers an initial indication of whether a road conversion would result in a loss of capacity given the roadway motor vehicle traffic demand.

New Project: Red Light Running Warning System
Red-light violations at traffic signals are a major contributor to crashes and fatalities. Right-angle type crashes typically account for the most serious of these collisions, and most of them are caused by vehicles running red lights. This research will explore technology that could be used to warn drivers when they are about to run a red light.
