Smart arrival notification system for americans with disabilities act passenger paratransit service with a consumer mobile device

This research presents an arrival notification system for paratransit passengers with disabilities. Almost all curb-to-curb paratransit services have a significantly large pickup time window, ranging from 20 to 40 min from the scheduled time and producing substantial passenger waiting times. The arrival notification system presented in this study delivers an automated voice call to a registered user once the paratransit vehicle is in proximity to the pickup location. The system utilizes the Google Traffic application programming interface (API) for the vehicle arrival estimation. Unlike other vehicle arrival notification systems in the state of the practice, the proposed system is compact and does not require additional equipment such as radio transmitting and positioning devices. The proposed system, which uses consumer mobile devices with the Android or iOS platform, is designed to exploit commercial cellular network service (i.e., 3G and 4G-LTE). In addition to the passenger notification, the proposed system provides paratransit drivers with real-time route guidance information developed through the Google Maps API. Field evaluation conducted in Essex County, New Jersey, revealed significant reduction in passenger waiting time. The passenger waiting time was reduced by 15 to 20 min. In addition, the accuracy of the notification system was tested. During the test, in almost all cases, the vehicle arrived 1 min earlier than the proposed arrival time.
