Cross-cutting Issues

This paper details information on the development of a guidance document for implementing real-time transit information systems that is scheduled to be published by the Federal Transit Administration in the second quarter of 2003. The guidance document is intended to provide relevant and practical information on planning, implementation, operational, and maintenance issues along with any solutions to the challenges faced by transit agencies that have successfully implemented real-time information systems. The background research for this guidance document included a literature review on existing systems and site visits and telephone interviews of key staff at selected transit agencies that have successfully deployed real-time transit information systems.

The Texas Transportation Institute (TTI) is performing the College Station Integration
Project to improve arterial operations and emergency vehicle routing at intersections with
railroad grade crossings within the project area. The focus is delivering real-time video
and rail monitoring information to the College Station Fire Department.
The critical task for this project is the design of a communications system for the corridor
that can handle high-bandwidth applications. This paper presents the results of an
analysis of the communications system needs, the range of possible solutions and the
reasons why Gigabit Ethernet was chosen for the solution. This paper also presents the
Phase I communication system design as well as a discussion of the challenges that still
remain. Innovative solutions for a full range of equipment needs in the traffic signal
cabinet are also presented, based upon the use of Gigabit Ethernet as the communications
backbone.

The automotive industry and the automotive Telematics sector in particular have come a long
way and the introduction of communications-based information systems is finally becoming a
reality. An increasing number of factory installed head units are supporting a wide range of realtime
information feeds for mobility, convenience and Infotainment applications. The increasing
amount of dynamic information poses challenges that need to be carefully considered in order to
avoid information overload and driver distraction. This paper provides a basic approach for
dealing with dynamic, integrated and open communications based information systems by
centrally managing HMI resources and granting HMI resources based on a well-defined and
centrally governed priority scheme. The proposed priority scheme depicted hereafter has been
implemented in the VII-C Proof of Concept.

At least 30 major cities and metropolitan areas in the U.S. have implemented real-time traffic-information web sites to provide pretrip traffic information. Although many web-sitedesign guidelines exist, no design guidelines were found specific to the construction of traffic-information web sites. The project upon which this paper was based set out to develop such guidelines. In the process, 4 methods used to help design a usable web site were evaluated: (1) user analysis, (2) heuristic evaluation, (3) guideline application, and (4) user testing. This paper describes the major findings from each method and the strengths and weaknesses identified for each method. Although there were distinct benefits from each method, guidelines use and user testing were found to be the most beneficial methods given the likely resources available in the Traffic Management Center (TMC) to develop a traffic-information web site.

Yellow Page (YP) information is playing an important role in business communication since the  service has been familiar with general public for over 50 years in Taiwan. YP Service is continuously improved with the modern technology from early directory service to modern electronic service. Now, the YP service can be served as the information exchanging for  customers, which just matches the spirit of Web 2.0. With more possible guest, it will be welcome  for young people and early bird services. There are several query methods of YP information:
by directory looking up, by phone call, or by web browser. In this paper, a location base  personalized YP service is designed and proposed for more active, gentle and convenient YP services in the future.
