PERCEPTION OF BUS RIDERS ON THE BENEFITS OF AUTOMATIC VEHICLE LOCATING SYSTEM

Abstract

This dissertation discusses the most commonly used fleet tracking technology, the Automatic Vehicle Locating (AVL) system in public transit operations in Singapore. Its main feature is its ability to track fleet in a real-time manner. AVL is a component under the Advanced Public Transportation Systems (APTS). A simple architecture of AVL system is explained. Its benefits to public transit bus operations are examined through various literature reviews. The main goal of this study is to find out the perception of public bus riders on the benefits of AVL system. Questionnaire survey is conducted to obtain primary data. The survey results show that the main attributes of AVL system for example real-time passenger information, delay notification and accurate bus schedules through historic AVL data are regarded as important to the bus riders. It also suggests that infrequent riders can be attracted to use more public buses and thus increases ridership if information is readily available. Key recommendations made after surveying bus commuters are comprehensive provision of fixed timetables, installation of onboard LED display panels, wider dissemination of real-time bus information to public, and usage of historic AVL data for troubleshooting and schedule refinement. The conclusions drawn from this study are that the basic benefits of AVL system are not yet maximized and that bus riders would appreciate more bus arrival information on schedule and real-time basis. It is also suggested that better passenger information would attract infrequent bus passengers to using more public buses and thus increases the overall ridership.
