Current mobile phones are becoming important platforms that serve the ubiquitous sensing and communication needs of people [29, 55]. The sensing and communication modules on mobile phones are usually developed to provide location and context-aware services. Real-time urban traffic conditions are critical to wide populations and serve the needs of many transportation dependent applications. This...

This study examines how bus design factors influence door crowding and quantifies how door crowding relates to operational performance and passenger safety. Results are based on data collected for 2,807 stops in Dhaka, Bangladesh. Door crowding is affected by multiple bus design factors, including door placement, aisle length, presence of a front seating area, and service type. Increases in doo...

We propose a Tabu search based technique for timeconstrained SOC (System-on-Chip) test data transportation. The technique makes use of the existing bus structure, where the advantage is, compared to adding dedicated test buses, that no additional routing is needed. In order to speed up the testing and to fulfill the time constraint, we introduce a buffer at each core, which in combination with ...

This paper investigates a routing problem in a public transportation network, more precisely — the problem of finding an optimal journey plan in the Silesian Bus Network, given a timetable. In our previous experiments we analysed the Ant System which was adapted to the Bus Routing Problem (BRP) [1]. Numerical experiments have shown that the evaluation function applied caused many difficulties a...

Enhancing a bus transit system is a possible solution to the growth of congestion in urban areas. Issues related to the safety of bus passengers, either on board or during their travel to a bus stop, should be considered. This article presents a GIS method to identify risky bus stops on a single bus route in the Serdang and Seri Kempangan area according to three attributes: location, characteri...

We present a method of learning a Bayesian model of a traveler moving through an urban environment. This technique is novel in that it simultaneously learns a unified model of the traveler’s current mode of transportation as well as his most likely route, in an unsupervised manner. The model is implemented using particle filters and learned using Expectation-Maximization. The training data is d...

1 Bus-stop consolidation is one of the most cost-effective ways for a transit agency to improve the 2 quality of their bus services. By removing unnecessary stops, buses will have reduced runtimes, 3 which can lead to higher frequencies and/or fewer buses on a route. Unfortunately, current 4 research on bus stop consolidation and stop spacing focuses on complex mathematical models 5 that are di...

As part of the ongoing effort to be independent of petroleum resources and to be free from pollutant emission issues, various electric vehicles have been developed and tested through their integration with real world systems. In the current paper, yet another application specific EV for public transportation, an electric bus, is introduced and explained with results from the pilot test program ...

Combined bus rapid transit and buses in a dedicated lane (CBBD) is measure that (BRT) operators implement to reduce overlapping routes between BRT fixed-route buses. The CBBD can combine the passengers of both systems on same route, which helps increase passenger demand for BRT, fuel consumption emissions from utilizing exclusive lanes combined route. However, could affect some terms either los...
