About Pedestrian Information and Communication Systems (PICS)
In Japan, the police bear the responsibility of traffic management, and tackle many problems caused by road traffic, such as traffic accident, traffic congestion and environmental pollution, using traffic management technique such as traffic regulation and traffic control. For this traffic management, NPA (the National Police Agency) planned UTMS21 (Universal Traffic Management System 21) and is installing it nationwide as one of ITS (the Intelligent Transport System) in our country. The UTMS21 consists of 10 subsystems, centering around ITCS (Integrated Transportation System). The PICS (Pedestrian Information and Communication Systems) introduced in this paper is also one of the subsystems of UTMS21.
PICS is intended to provide information through voice and image, in addition to the conventional function of Audible Traffic Signals, Weak-actuated Traffic Signals and Pedestrian-actuated Traffic Signals. By these functions, PICS will provide the pedestrians with safe, convenient and comfortable mobility and help people expand the area of travel.

When Will My Bus Arrive? - A Look at Transit Arrival Signage at Stops Via Wireless Communication
The main goal of Intelligent Transportation Systems (ITS) is to improve the overall efficiency of transportation systems by using modern computers, communication, and data processing technologies without substantial capacity additions to the network (Tarko and Rouphail 1997). Surveys show that, next to safety and security, traffic information is among the services most desired by motorists (Orski 2001). Travelers have an implicit expectation that high-technology services have equally high-technology content.

Vehicle Speed Information Displays for Public Websites A Study of User Preferences
The paper reports on a study comparing alternative presentations of freeway speed data on maps. The goal of the study was to inform the design of displays of real-time speed data over the Internet to the general public. Subjects were presented with a series of displays and asked to rate their preference. We looked at different choices of color (3 colors, 6 colors or a continuous range), and proposed line, sensor, and segment representations of the speed data. We also collected feedback on more complex displays such as comparison between current and "normal" speeds, and a chart of speed variation over a period of time at given locations. Finally we discuss issues of color blindness.

Use of Technology Review for Identification of ITS Market and Equipment Packages
This paper illustrates the use of a technology review as part of a regional ITS Architecture development. The paper identifies market and equipment packages that are available in the market but are not defined as part of the National ITS Architecture. These packages include Pedestrian Management and Information, Surface Street Control Enforcement, Joint-Use Vehicles, Parking Facility Enforcement/Security, Automated Parking Systems, Vehicle-Based Transit Information, Advanced Commercial Vehicle Safety Advisory, Emerging Probe Surveillance Technologies, and Speed Limit Enforcement/Dynamic Speed Limits.
The results presented in this paper indicates that a review of existing ITS technologies and products is useful in identifying market packages/equipment packages that meet specific regional, local and project needs.

TripInfo: Integrating Traveler Information Using XML
Traveler information is exchanged between public sector agencies, private companies, and private citizens. The World Wide Web is one of the most widely used dissemination mechanisms, along with voice telephony. Wireless Web access is rapidly growing. Most Web-based information exchange, however, can be classified as semi-automated. The information is primarily formatted for, presented to, and used by a human. The information is formatted for presentation using HyperText Markup Language (HTML). It is difficult to cost-effectively automate the processing of large amounts of HTML coded material, because the HTML doesn’t provide information about the meaning of the data, just how to present it. For this reason, the Web has not been a particularly attractive mechanism for fully-automated exchange between computer systems.
This paper describes the TripInfo proof-of-concept prototype. TripInfo has successfully demonstrated the applicability of XML to traveler information integration. TripInfo uses XML to integrate traveler information from multiple sources, and provide trip-based, rather than inkbased reports. The rational for the project, the project itself, and the lessons-learned are described.
