An Application of Multimedia Services on Transportation: The Use of the World Wide Web (WWW)

INTRODUCTION In recent years, there is an ever-increasing demand and interest in the use of multimedia technology and applications in industry, government and academia. Multimedia is often seen by researchers as the next step forward in interfacing science, technology and community. Yet, the terminology of multimedia bears several meanings. It may refer to Compact Disc (CD), moving pictures or video-conferencing. The multimedia technology referred in this paper is the World Wide Web (WWW) hypertext publishing information system which was developed by and started at the European Laboratory for Particle Physics (CERN) in Geneva, Switzerland. Since the introduction of WWW, its use has increased dramatically within a couple of years in a widely diverse community including government departments, university and research establishments, and commercial organisations. It has significant influence to our communities and our daily lives. Yet, in most cases, applications of WWW services are largely restricted to electronic library referencelcatalogue search facilities, electronic mail systems, electronic conference and discussion systems, electronic news and publishing agents, and remote access to computing resources on the Internet. The primary objective of this paper is to exploit the potential of this multimedia technology as a simple, easy-to-use and effective means of telematics application in transportation research. It is hoped that initiatives are highlighted via this study and hence encourage participations and collaborations from different sectors of industries. In this paper, a brief history of WWW is given in section (2). An overview of the technical aspects in providing a WWW service is presented in section (3) in terms of computer hardware requirements, software installation, network connections, application maintenance and administration, and system security. Compared to most commercially available multimedia software in the market, WWW services are cheap to run, userfriendly and readily available to the public on the Internet. In order to exploit the potential of WWW on transportation research, a study was carried out and results of the findings are reported in section (4). To further substantiate the level of usefulness, two particular WWW applications were chosen amongst other web services and they are reported in section (5) for illustrative purposes. The selected applications are the 'Transportation Resources on the Internet' developed in mid-1994 in the Institute for Transport Studies (ITS) at the University of Leeds in England, and the 'Southern California Real-Time Traffic Report' developed by Maxwell Laboratories, Inc. in collaboration with the California State Department of Transportation in the US. Finally, a set of issues are raised in section (6), highlighting the directions of future development of WWW as an easy-touse, cheap and effective multimedia telematics application on transportation

Propensity to Consider Cycling for Commuting Trips

The British Government launched the National Cycling Strategy (NCS) in July 1996. The aims of this strategy are to establish a culture favourable to the increased use of bicycles for all age groups, to develop sound policies and good practice, and to seek out innovative and effective means of fostering accessibility by bicycle. The central target is to double the amount of cycle trips on 1996 figures by 2002; and double it again by 2012. It is hoped that these increases in cycle trips are as a result of people switching their current mode to bicycle. With this increased interest from national and local governments, there is likely to be increasing demand for rigorous evaluation of proposed schemes in terms of increases in levels of cycling, modal shift and, ultimately, the quantified benefits to existing and potential cyclists. Yet, in contrast to the vast amount of research which has been done on enhancing our understanding of the demand for motorised vehicles, relatively little attention has been paid to the slow modes (i.e. walk and cycle). Furthermore, most studies on existing and potential demands for cycling are qualitative rather than quantitative in nature. For instance, attitudinal factors of choosing or not choosing cycling are well documented. However, magnitudes of different factors are seldom calculated. An Economic and Social Research Council (ESRC) sponsored project entitled “Cycling and Urban Mode Choice” (Grant Number: R000237103) started in mid-1997, aiming to identify and quantify the factors that might influence people’s decision to travel to work in urban areas. The aim of this paper is to report the findings of the first stage study of this research project. The first stage study of the “Cycling and Urban Mode Choice” project was to identify and measure the proportion of the general population who would or would not consider cycling to work in urban areas. This study was based on detailed surveys (door-to-door and telephone interviews) of people’s actual mode choices on two what-if situations. The first hypothetical situation is based on provisions of cycle facilities and routes, and the second rests on drastic changes of the current situations of journey to work. Models were built on the survey data to explain people’s choices between driving car, getting a lift, bus, walk and cycle for the journey to work trips
