This position paper examines some of the privacy features required in context-aware transport applications. We begin by describing why pseudonymity is preferable to access control for protecting privacy. We then present three sample transport applications and describe the key pseudonymity features that could be provided by a transport middleware framework; these features enable applications to ...

This paper proposes a model for estimating car delays at bus stops under mixed traffic using probability theory and queuing theory. The roadway is divided to serve motorized and nonmotorized traffic streams. Bus stops are located on the nonmotorized lanes. When buses dwell at the stop, they block the bicycles. Thus, two conflict points between car stream and other traffic stream are identified....

In this paper, we propose an intelligent bus status informing scheme based on smartphone application to increase convenience of public bus system by providing the seating capacity and number of passengers of the coming buses to waiting persons at the bus stop. The proposed scheme not only provides a real-time information of the number of passengers in the bus, also helps people to know whether ...

A municipal solid waste (MSW) and recycled material curbside pickup bus system was recently initiated in a Taiwan city to improve collection service. For such an MSW pickup system, selecting appropriate collection stops critically affects hauling costs and service efficiency. Conventionally, MSW collection points are heuristically and manually chosen, resulting in a hauling system that is not a...

Automatic Vehicle Location (AVL) and Automatic Passengers Counters (APC) systems have been increasingly implemented by transit agencies for the real time monitoring of transit vehicles and automatic counting of passengers boarding and alighting at bus stops. As a result, a vast amount of potentially online data related to transit operation could be obtained from these systems. The emphasis of t...
