Benefit Summary HTML

This study sought to assess and mitigate the effects of dynamic message signs (DMSs) on highway traffic. A review of traffic data found that many motorists slowed as they approached an active DMS and then increased their speed after passing the active DMS. The researchers identified that this speed variation could pose safety hazards to other motorists. The study identifies the effects of active DMSs on highway traffic using a sample from Rhode Island and identifies measures to improve the design and display of DMS messages to help mitigate speed variations of approaching traffic through the use of a questionnaire and driving simulation experiment.

This study assessed effects of dynamic message signs (DMSs) on highway traffic. Traffic data from a sample collected in Rhode Island found many motorists slowed while approaching an active DMS and then increased speed after passing the active DMS. This speed variation could pose a safety hazard to other motorists. The study identified effects of active DMSs on highway traffic and learned lessons about how drivers read and interact with different types of messages displayed on a DMS.
