Creating a Situation-aware Sensing Environment for Cyclists: An Innovative and Cost-effective Smartphone-based Approach

项目名称：	Creating a Situation-aware Sensing Environment for Cyclists: An Innovative and Cost-effective Smartphone-based Approach
摘要：	This research will assess the feasibility and effectiveness of a Biker Assistance System (BAS) in different roadway contexts using a prototype mobile application. The application would make use of smartphones’ onboard speaker and microphones to monitor potential hazards and help bicyclists avoid crashes. The application will detect potential hazards by emitting an imperceptible sound and interpreting its reverberations, thus becoming a “mini-sonar system.” When certain potential hazards are detected, the smartphone will alert bicyclists of the hazard. This new approach to preventing bicycle crashes has yet to be developed or tested to the researchers’ knowledge. This project has four components. First, the project team proposes to analyze existing crash data sources to understand the types of crashes that can be prevented or mitigated with BAS. Second, the team proposes the development of the BAS for at least two hazardous scenarios – right turning vehicle detection and front/overtaking vehicle nearing. Additional scenarios may be added based on the crash data assessment. Third, a bike simulator study will be conducted to determine effective alerts for selected hazards. Based on the simulator study outcomes, a list of multi-modular alerts will be recommended which can be easily understood and interpreted by cyclists under both day and night lights. These alerts will be included in the BAS prototype. Finally, the project team proposes testing the efficacy of BAS in these scenarios via physical testing and naturalistic observation using an instrumented bicycle. This naturalistic database will be used to identify the critical cyclists-vehicle interaction regions and scenarios. Future research will expand the sensing capacity to function in different crash scenarios, investigate cyclists’ interactions with different road users, and provide cyclists with feedback to avoid different types of on-road hazards.
