This paper explores impacts of ramp metering on urban land use. A regression-based transportation model is developed to capture changes in accessibility caused by ramp metering on a highway network. A Land Use Change Indicator (LUCI) model is modified to estimate how the spatial distribution of employment and housing would change in response to the redistributed accessibility in five hypothetical urban areas with various initial land use patterns. Results show that ramp metering can affect land use in various ways depending on initial land use conditions. Ramp metering can exacerbate decentralization, but not necessarily sprawl.

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.

Since the US DOT released the Final Rule 940 in April 2001that requires the development of a regional ITS architecture for all metropolitan areas, most regions have initiated or completed an ITS architecture. The first step in the ITS architecture development process is to conduct an extensive discussion with the region’s stakeholders. While every region has different transportation, public safety and security issues, there are a number of common themes emerging from stakeholder discussions across the country.

This paper describes some of these common themes and some differences in ITS functions generated by local issues. The comments expressed in this paper are based on the experience of the author and are not been confirmed by research or analysis of data.

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.

The Ports ATMIS, which will improve traffic flow for both Ports as well as the adjacent regional transportation system, consists of the following components: 1. Port Transportation Facility Security System/Emergency Response and Evacuation System 2. Advanced Transportation Management System (ATMS) 3. Advanced Traveler Information System (ATIS) 4. Communication System

The authors hope that this paper would benefit those agencies intersted in development of an ITS program focusing on a Systems Engineering approach that included Concept of Operations and Configuration Management.
