Abstract
A variety of emergency situations may occur around us at any time in our daily life, especially in an unfamiliar place. For example, a tourist may seek medical treatment for an accidental wound or encounter a problem like running out of gasoline, raising the urgent requirements where to find specific services nearby for help. In this paper, we develop a guidance system, HelpMe, benefiting the mobile-phone user with self-rescue instructions when needed. HelpMe provides reasonable instructions by leveraging the urban transportation patterns discovered from massive historical trajectories of vehicles and an efficient route planning algorithm based on these patterns. Within the process of route planning, HelpMe introduces a novel reach-time-cost model to sort out the candidates of emergency service spots, such as hospital, police station and gas station and so on, as well as the fastest way to the destination. Capturing the current locations from a mobile phone, HelpMe can suggest the phone user where to find secured transport assurance with the highest probability and automatically guide you to the destination by the fastest route. Our experiments have revealed satisfactory conclusions and demonstrated the effectiveness of our system.
