AHS for Making Traffic Flow Smoother by Optimizing Lane Utilization Rates at Expressway Sag Sections

As part of the Next Generation Road Service scheduled to start test operation in 2007, the authors are currently working on traffic smoothing services by optimizing lane utilization rates using AHS (Advanced Cruise-Assist Highway System). To date, dip sections are focused, which are a main cause of traffic congestion on Japan's intercity expressways. Utilizing AHS image processing sensors, time and spatially consecutive traffic phenomenon characteristics were grasped and analyzed. Based on the analysis, a service proposal for a specific dip section was drawn up. Drivers' acceptance of the service was proved by driving simulator tests, and proving tests on the actual sag section were conducted. This paper reports some of the test results. For the covering abstract see ITRD E140665.
