Non-motorized road users are requiring more efficient and user-friendly infrastructure facilities with improved equity, especially at the intersection areas. However, most existing achievements in this field either proposed overcomplex solution and led to lacking reliability and scalability, or proposed something that were not keeping pace with time enough to improve users’ accessibilities. Therefore, in this research, a new system is proposed to replace the traditional push-button switch or traffic lights. The system utilized a roadside device as the communication media between signal controller and user, and users only need to install a mobile phone app to use the system. Compared to existing similar solutions, our solution introduced a smart gateway to achieve multiple protocols integration. The proposed phone app that can also classify users according to their motions, different non-motorized user groups can now easily view their waiting time and sending crossing request manually or automatically without searching for the physical push-button switch and press it. Our experiments indicates that our system is a touch-free, quick responding, reliable and highly accessible for all user groups. In addition, this proposed system is the first equity-aware solutions for both normal and vulnerable users and can completely replace the traditional physical push-button system.application/pdfen-USnoneCommunicationIntersectionITSMobile PhoneTransportationTransportationTransportationCivil engineeringMobile-Device-Based Solution for Non-motorized Users and Traffic Signal Control System InteractionsThesis
