The Crosswatch Traffic Intersection Analyzer: A Roadmap for the Future
نویسندگان
چکیده
The “Crosswatch” project is a smartphone-based system developed by the authors for providing guidance to blind and visually impaired pedestrians at traffic intersections. Building on past work on Crosswatch functionality to help the user achieve proper alignment with the cross-walk and read the status of Walk lights to know when it is time to cross, we outline the direction Crosswatch should take to help realize its potential for becoming a practical system: namely, augmenting com-puter vision with other information sources, including geographic infor-mation systems (GIS) and sensor data, to provide a much larger range of information about traffic intersections to the pedestrian.

Determining a Blind Pedestrian's Location and Orientation at Traffic Intersections
This paper describes recent progress on Crosswatch, a smartphone-based computer vision system developed by the authors for providing guidance to blind and visually impaired pedestrians at traffic intersections. One of Crosswatch's key capabilities is determining the user's location (with precision much better than what is obtainable by GPS) and orientation relative to the crosswalk markings in ...

متن کاملAn Optimal Dynamic Control Method for an Isolated Intersection Using Fuzzy Systems
Traffic flow systems are nonlinear and uncertain, so it is very difficult to find their optimal points. In traditional traffic control systems, the traffic lights of crossings change in a fixed time period that is not optimal. On the other hand, most proposed systems are sufficiently capable of coping with the uncertainties of traffic flow. To solve this problem, there is a need to develop expe...
متن کاملEffect of Gap Acceptance Behavior of the Right Turning Vehicles on the Major Road Stream for Uncontrolled Three-Legged Intersections under Mixed Traffic Conditions
Uncontrolled intersections are the intersections where there are no external signs or signals to control the movement of vehicles. In mixed traffic conditions priority rules are often violated by the road users. In All-way-stop-controlled intersections (AWSC), the vehicle should stop themselves before they enter the intersection and should check whether any vehicles are present in the other app...
متن کاملImproved Skips for Faster Postings List Intersection
Information retrieval can be achieved through computerized processes by generating a list of relevant responses to a query. The document processor, matching function and query analyzer are the main components of an information retrieval system. Document retrieval system is fundamentally based on: Boolean, vector-space, probabilistic, and language models. In this paper, a new methodology for mat...
