A wheelchair system includes one or more servers. A software application is provided by the server(s) to be installed on a computing device (such as a mobile phone) communicatively coupled with the server(s) through a telecommunications network. One or more user interfaces displayed on the computing device, using the software application, include a traffic navigation selector configured to receive a user selection indicating that a wheelchair operator is preparing to cross a street. In response to a selection of the traffic navigation selector the software application may: determine whether vehicles are nearby； notify the wheelchair operator when to cross the street； notify the wheelchair operator how much time is left to cross the street； visually record the wheelchair operator crossing the street； and determine, based on receipt of sensory input from computing device sensors and wheelchair sensors, whether an accident has occurred and, if so, notify emergency personal and family/friends.
