Context-aware middleware is considered as an efficient solution to develop context-aware application, which provides a feasible development platform integrating various sensors and new technologies. With the development of sensors, the research work on the context shift from “location” to “activity” gradually. Then it puts forward a new requirement for context-aware middleware: activity context...

In highly populated urban zones, it is common to notice headway deviations (HD) between pairs of buses. When these events occur in a bus stop, they often cause bus bunching (BB) in the following bus stops. Several proposals have been suggested to mitigate this problem. In this paper, we propose to find BBS (Bunching Black Spots) – sequences of bus stops where systematic HD events cause the form...

Recently, web services to access from many type devices are often used. We have developed the shortest path planning system called ”Bus-Net” in Tottori prefecture as a web application to sustain the public transport. And it used the same user interface for both devices. To support both devices, the interface cannot use JavaScript and so on. Thus, we developed the method that use individual user...

An Improved Bus Signal Priority System for Networks with Nearside Bus Stops. (December 2004) Wonho Kim, B.S., Chungbuk National University; M.C.P., Seoul National University Co-Chairs of Advisory Committee: Dr. Laurence R. Rilett Dr. Amy Epps Martin Bus Signal Priority (BSP), which has been deployed in many cities around the world, is a traffic signal enhancement strategy that facilitates effic...

Despite the decline in numbers of crashes and fatalities U.S. since 1990, pedestrian have been steadily increasing reached its 28-year peak 2018. This increase led to initiatives such as Vision-Zero response this deterioration safety. In spite severe outcomes crashes, guidelines are still not fully capable alleviating safety issues formulate performance functions; mainly due scarcity data, part...

The planning and managing of bus networks as a urban public transport system is a relevant problem. Several proposals focus the planning of new bus networks. In this paper, we focus the speci c task of reallocating buses from di erent lines of a previously planned bus network in case of restrictions, such as vehicle breakdowns and drivers absences. Our proposal uses a fuzzy decision tree, which...
