Mega cities around the world are suffering from severe traffic congestion resulting in
economic losses via delayed time, fuel consumption, traffic accidents, air pollution and traffic
noise.  
Mitsubishi Heavy Industries, Ltd. (MHI) is responding to the growing momentum for the
introduction of road pricing. MHI developed an urban environment-friendly road pricing
concept called IURP (Integrated Urban Road Pricing), and successfully conducted
demonstration tests. This paper describes following items;
1) Requirement for DSRC based IURP
2) One of IURP solution: System Overview and Technical descriptions
3) Evaluation and Demonstration test
4) Extensibility of Active DSRC based IURP

The objective of this paper is to define a performance measure(s) that can be used to show congestion levels on critical corridors throughout Virginia and develop a general methodology to select and calculate performance measures in order to quantify congestion in a transportation system. These measures can be interpreted to provide benchmarks or base values of congestion to provide a means for measuring change in the performance of the highway system.

Currently, many federal/state/local agencies are providing diverse public transportation service at the historically slow-growth rural areas. The integration of these available rural transit services can be greatly enhanced with the automated demand-responsive transits, and coordinated transit service equipped with the Intelligent Transportation System and Information Technology (ITS/IT) technologies. This paper discusses both the available ITS technologies and existing institution barriers that are essential to improve the quality of life at the rural communities.

The GCM Gateway TIS is currently being developed as the central traveler information hub for the Gary-Chicago-Milwaukee Corridor and will be operational this fall to replace an existing legacy system. The Gateway TIS collects transportation related information from geographically widely distributed agencies of varied natures, validates and fuses the information collected, and disseminates it to interested public and private entities and the general public via internet and intranet. The Gateway handles a wide spectrum of data types, including traffic related incidents, roadwork and special events, vehicle detector data, DMS (Dynamic Variable Sign) and HAR (Highway Advisory Radio) messages, weather sensor data, traffic operational parameters derived from electronic toll collection system. Eventually, The Gateway will also provide real time video services.

This paper presents at a high level the CORBA based system architecture design of the Gateway system primarily from the perspective of ITS Center-to-Center interoperability. It also introduces the object oriented Gateway external data model that is specified in CORBA IDL (Interface Definition Language) and the Gateway Publisher/Subscriber based message oriented middleware for data collection and distribution. In addition, the Gateway’s decision on the selection of object oriented DBMS (Database Management System) versus relational DBMS is also discussed.

This article presents an express lane network concept called “High Occupancy
Vehicle-Credit” or HOT-C lanes that could be implemented in a short period of time.  A network of free-flowing express lanes would be created by re-striping freeways to convert the left general-purpose lane(s) into HOT-C lanes during rush hours and creating a dynamic shoulder lane on the right side to replace the converted left general-purpose lane.  To gain public acceptance, a limited quota of credits would be made available to all employees in the
metropolitan area for free use of the lanes during rush hours.
