Abstract

Abstract: With the progress of modern technology, more and more vehicles arise on the road, which may cause some congestion and a high level of exhaust emission, such as CO 2 and NO x . As an environment friendly trip mode, walking should be encouraged. Pedestrians are definitely a non-negligible group participating especially in urban traffic. Therefore, a control system of pedestrian-crossing speed is proposed in this work, which is similar to the "Green Light Optimal Speed Advisory (GLOSA)" for motor vehicles. It can not only provide pedestrians with the dependable speed recommendation to walk but also the optimal path to follow. A smart-phone-app is finally designed to validate and test such a system. And the result comes out that such an app works significantly fine especially when pedestrians are faced with multiple choices at intersections. The result indicates that crossing with the app with GLOSA can reduce respectively 41.62% and 35.21% of used time on average, compared with crossing in the fixed paths. It can still save 27.86% of the average time, compared with the behavior of choosing the path in green time first.
