Travel Times on Changeable Message SignsVolume Ill - Travel Time

Real time traffic information on Changeable Message Signs (CMS) has gained popularity in urban areas where congestion and incidents frequently affect vehicle travel. CMS have been used to broadcast information about corridor downstream delays, traffic incidents and estimated travel times. Displaying accurate travel times on CMS helps commuters assess traffic, alleviates driver's stress, and allows drivers to make better route decisions. Knowing the driving times to popular destinations, travelers may be able to map their driving to the less congested route or chose a different form of transportation. Moreover, signs are the most effective means to communicate real-time, relevant information to motorists. Unlike a radio broadcast, signs target drivers passing a given location. Hence, the message ishighly likely to be of interest to those drivers.
