What is it about?
The understanding of drivers' en-trip route choice response to graphical route information panels (GRIP), a new form of variable message sign technology, is so far very limited. This paper quantify the impacts of GRIP on drivers' route choice in the context of China using the discrete choice analysis method. It's based on data collected from a stated preference survey in Shanghai.
Why is it important?
The developed driver GRIP response model has a potential to be incorporated into a dynamic traffic assignment and simulation framework, thus helping better assess the effects of advanced traveler information systems.
