Evaluation of Non-Intrusive Technologies For Traffic Detection
This paper presents results from Phase II of the Field Test of Non-Intrusive Traffic Detection Technologies (NIT project). The project was sponsored by the Federal Highway Administration and was conducted by the Minnesota Department of Transportation and SRF Consulting Group. The sensors were tested in a variety of mounting locations at both intersection and freeway test sites. Emphasis was placed on urban traffic conditions, such as heavy congestion; locations that typify temporary counting situations, such as 48-hour or peak hour counts; and real-time applications that support ITS activities.

Connecticut's Recent Experience in Statewide Consolidation of Events using New TMS Software CRESCENT
The rules and templates used by CRESCENT have been established through a joint effort between ConnDOT operations personnel and the development team of IBI Group and Fuss & O’Neill. Although there was significant upfront work required in developing the rules and templates, the result is a CRESCENT system that provides incident management that is applicable across the state, regardless of where an event occurs.
This paper examines how CRESCENT was developed with a statewide perspective in mind. Specifically, this paper explains the history behind the CRESCENT system, the principles and methodology behind the development of the software, the significant with the operation of CRESCENT, and the next steps in the continued evolution of the system.

Development of Traffic Estimation and Prediction Systems - Overview of Dynamic Traffic Assignment
The success of Intelligent Transportation Systems (ITS) depends on the availability of timely and accurate estimates of prevailing and emerging traffic conditions. To meet the traffic information needs and to address complex traffic control and management issues in the information-based, dynamic ITS environment, the Federal Highway Administration (FHWA) initiated a Dynamic Traffic Assignment (DTA) research project to develop a deployable real time Traffic Estimation and Prediction System (TrEPS). Two TrEPS prototypes, DynaMIT and DYNASMART-X, have been developed and are currently being planned for testing in the field environment. This paper provides a brief introduction to the DTA research project and the status of the TrEPS development and deployment.

Expanding the Contect of NTCIP Standards - Helping Stakeholders Achieve Implementation
Just as the ITS National Architecture introduced “systems engineering” to many practitioners in the transportation community, the new NTCIP content will further help transportation professionals with their system engineering of ITS. The new NTCIP document content will: help determine user needs; relate functional requirements; define how the functional requirements are to be implemented in a common, unambiguous way; and help develop test procedures. This paper explains the content of the document sections, and how to use that content, for the revised NTCIP standard documents.

Histogram Analysis of Transit Bus Real-World Data
Developing a frontal collision warning system (FCWS) for transit buses is considerably much more difficult than that targeted to highway applications due to the significant differences in operating environments. In this paper, a histogram analysis was applied to several months of real-world data collected on an experimental bus in normal service in San Francisco Bay Area. This analysis addresses the unique characteristics of the operational environment of transit buses. Figures and pie charts as well as analyses are presented.
