Innovative Solution Helps NEXTRANS Model Travel-Time Reliability

Researchers at Purdue University and the NEXTRANS Center (Region V Regional University Transportation Center) are applying cutting-edge technology to develop a model that can accurately measure travel-time reli­ability. This model may provide a new basis for transportation professionals to monitor the performance and benefits of activities implemented on roadway networks. 

Travel-time reliability is a key perfor­mance measure in any transportation system. It affects the routes commuters choose, impacts the on-time reliability of freight shipments, and reflects the ef­ficiency of the transportation system to serve citizens, businesses, and visitors.
