This paper summarized the software design within the GLITS (Great Lakes ITS) I-75 Freeway and Arterial Integration project. The GLITS I-75 Project was a pilot project of the Integrated Corridor Management (ICM) aimed at coordinating freeway and arterial operations to quickly release freeway bottlenecks by optimizing the parallel arterial road’s capability to accommodate traffic diversion from the freeway. This software framework links two different types of traffic management systems (freeway and arterial) and smoothly integrates corresponding functions together, minimizing the changes of their existing architectures. The paper will include the following aspects: 1) Functions requested to coordinate the freeway and arterial operations within GLITS I-75 Project; 2) Existing software architecture analysis for both freeway management and arterial management; 3) Concept of the collaborative software framework; and 4) GLITS I-75 Project software design summary.

The objective of this project was to implement and evaluate a low-cost system that can
accurately estimate arterial travel times (suitable for use in traveler information systems) with
only minor revisions to Mn/DOT’s standard detection layout. A secondary objective is to
provide automatic mainline turning movement counts at a level accurate enough for traffic
analysis and signal timing work. This project will use a University of Minnesota developed
technology (SMART-SIGNAL) that logs, at a high resolution, real-time intersection data,
including signal controller events and detector data, whereby arterial performance measures such as travel time, queue length and progression quality can be estimated. The system will be
evaluated by comparing manual traffic count and travel time data to the values estimated by the SMART SIGNAL system.

This paper/presentation looks at possible methods to increase capacity on existing
motorways by utilizing available shoulder space and/or reversing traffic lanes during
peak hours, and also reversing on/off current motorway ramp configurations (moving
to a system of off/on instead of on/off). This procedure results in capacity gains of
40-50% without widening the motorway, just using the space available in a more
efficient .manner, and utilizing ITS and “Smart” techniques to help make it happen.
The purpose of the paper/presentation is to more fully explore existing and proposed
Hard Shoulder and ITS (ATM, or Active Traffic Management) techniques in the UK,
Europe, and the US, and to help determine cost effective methods to adding capacity
to existing Motorways.

The Michigan IntelliDrive (also known as Vehicle-Infrastructure Integration or VII) Test Bed
has been operational for over 12 months over which time we have experienced some
challenges that resulted in valuable lessons learned related to the Installation and Operations
and Maintenance of the Test Bed. This paper provides a high level description of the MI Test
Bed, discusses some of the Installation challenges, provides an overview of the current
Operations and Maintenance procedures, and provides some recommendations for future
deployments.

Kimley-Horn and Associates partnered with the City / County Association of
Governments of San Mateo County (C/CAG) and Caltrans to design and develop an
alternate route guide for incident management. The routes will be equipped with various
Intelligent Transportation System (ITS) elements such as cameras, trailblazer signs,
traffic signal timing improvements and system detection for proactive management of
traffic during freeway incidents. The goal of the program was to prepare a set of traffic
management strategies that reduce traffic delay of road users and queuing on the freeway
section. Geographical Information System (GIS) software (ESRI ArcGIS 9.2) was used
to develop the alternate routes guide, and to analyze the locations of the ITS elements for
any potential environmental disturbance before implementation. This paper discusses the
design and technical issues encountered during the development and analysis of the
Alternate Routes for Traffic Incidents (ARTI) Guide.
