EasyTracker is an automated system that assists small public or private transit agencies in deploying bus tracking and arrival time prediction. This demo will showcase how data from GPS sensors embedded in smartphones can be automatically processed in order to accurately estimate routes, bus stop locations, schedules, and make annotated maps with real-time bus tracking and arrival time predicti...

Public transit service is a promising travel mode because of its potential to address urban sustainability. However, current ridership of public transit is very low in most urban regionsö particularly those in the United States. Low transit ridership can be attributed to many factors, among which poor service quality is key. Transit service quality may potentially be improved by decreasing the ...

Currently in many major cities, public transit schedules are disseminated through lists of routes, grids of stop times and static maps. This paper describes a web based geographic information system which disseminates the same schedule information through intuitive GIS techniques. Using data from Calgary, Canada, an map based interface has been created to allow users to see routes, stops and mo...

Scheduling of a bus transit system must be formulated as an optimization problem, if the level of service to passengers is to be maximized within the available resources. In this paper, we present a formulation of a transit system scheduling problem with the objective of minimizing the overall waiting time of transferring and nontransferring passengers while satisfying a number of resource- and...

We present two formulations of a model for nding equilibrium passengers and operators ows in a partially regulated transit system where bus operators are free to choose the routes where they o er public transport services. The transit fares are assumed xed and known. The model o ers a detailed representation of the transit system network and of the transit users behavior. Congestion e ects are ...

Transit services are currently facing several challenges in the United States and around the world. For many reasons, among which the fluctuations in gas prices and the state of the economy are the major ones, transit demand has noticed a considerable increase. The challenge that transit agencies are facing is to make these increases permanent by maintaining transit’s competitive edge over the ...

A major research gap is the relative ridership performance of Bus Rapid Transit (BRT), Light Rail Transit (LRT), and streetcar (SC). This paper assesses ridership influences of 101 routes in Australia, Europe, and North America using multiple regression examining the influence of transit mode, vehicle capacity, service level, employment/residential density, car ownership, speed, stop spacing, r...
