Studies & Reports - The Smart Crosswalk™ System

Studies & Reports

To date there have been numerous studies determining the effectiveness of IRWL enhanced crosswalk systems in a variety of settings. For instance, studies comparing overhead signal lights to in-pavement signal lights. Studies have been conducted to determine ideal in-pavement signal light placement and the effectiveness of uni-directional IRWL systems. All the studies conducted on IRWL enhanced crosswalk systems lead to the same conclusion: the incidence of conflict between pedestrians and vehicles is markedly decreased and pedestrian safety is significantly increased.

Listed below are a selection of studies and reports on LightGuard’s IRWL crosswalk systems:
