Critical Appraisal of Web-Based Passenger Information Systems

Passenger information is vital for developing a user-friendly public transportation system. Websites are rapidly gaining popularity for public transport information dissemination, particularly due to their anytime-anywhere availability and their suitability for the multimodal applications and multilingual interface. Internet-based Passenger Information Systems (PIS), therefore, have become common in developed countries. The development of PIS for urban transport in India however, is at an experimental stage with very few operational deployments. This paper attempts to examine the current state-of-the-art features in Web-based passenger information systems in India and abroad, while critically evaluating the existing sources of public transport information in Ahmedabad as a case study. Ahmedabad, like several other Indian cities, has fixed-route regular bus services in conjunction with a recently-introduced bus rapid transit (BRT) system. The study compares the information content in printed transit timetables, Google Transit, and websites of the transit agencies, with the spatial dataset of public transport network prepared by integrating information from several sources. The results highlight the issues pertaining to accuracy, coverage, and timeliness of information contents available in developing countries, requiring innovative technological interventions to meet the growing information needs of commuters
