Transit ITS Implementation - Lessons Learned from Project Manager's Point of view
Over the past decade, more and more transit agencies have elected to implement Intelligent Transportation Systems (ITS) technologies to enhance their operations. Project managers face additional significant challenges because these projects are often complex in nature and involve multiple disciplines. Furthermore, the project manager must be able to navigate through the complicated implementation process to ensure the project’s success.
A successful ITS project should utilize the proper technology that suits the agency, satisfies the internal and external customers, and enhance operational efficiencies. Adopting the proper technology is crucial to ensure the project’s success. The technology must be suitable for the agency’s specific need and for the region. There are typically two types of transit ITS project managers — one with information technology background, and the other with transit background. Each type of project manager must overcome these shortcomings in order to implement the project. In addition, each must learn project management techniques to properly manage these projects successfully. As with any project of this nature, changes are inevitable and project priorities are constantly shifting. Project managers are required to be flexible and adaptable to new system and users’ requirements and needs.
This paper attempts to provide lessons learned for project managers from non-information
technology disciplines in order to guide them through the complex and complicated ITS implementation process. With this information, project managers should be able to foster cooperation among team members and deliver a successfully project.

Innovative Approaches to ITS Integration and Contract Delivery
This paper presents innovative approaches to challenges associated with the deployment and
operation of Intelligent Transportation Systems. The first of two topics, integration, will be
addressed through the examination of the Massachusetts Regional Traffic Operations center
(RTOC) case study, while the second major interest, unconventional performance-based
contractual set-ups, will be analyzed through consideration of both the RTOC as well as
innovative approaches such as the Highway Agency Traffic Control Center (TCC) project in
England.

Operational Test of Low-Cost Active Warning System for Low-Volume Highway-Rail Intersections in MN
Through this operational test, the Minnesota Department of Transportation (Mn/DOT) hopes to determine whether a newly developed low-cost active railroad crossing warning systemfunctions as well as traditional active system at low-volume highway-railroad intersections; andto determine whether the low cost system’s addition of flashers on advance rail warning signsprovides any additional benefits.The high level requirements and much of the design are complete. Six months of system analysisand testing has shown many functions to operate as required but has also raised a few questions. The system is being modified to address these concerns and further analysis and testing will beconducted in the late summer of 2003. Project activities are currently focused on failure modesand effects analysis, hazard analysis, and system validation. The project team is working closelywith the Federal Railroad Administration (FRA) in performing the system safety validation. Field tests indicate crossing warning times in the 27 to 28 second range regardless of train speed. The system demonstrated the ability to properly detect a train that stops on the approach and theneither proceeds or backs away. During a 33 day mid-project evaluation, the system performed without failure in 493 trainencounters. Warning times were within the range of 25 to 30 seconds 98.9% of time and allwarning times were 20 seconds or greater. The system accurately tracked daily train movementsand maintained global positioning system (GPS) communication at 99.76%. The independentevaluator will conduct another evaluation that encompasses the whole project period includingthe forthcoming one year operational test. If successful, this newly developed low-cost system offers the opportunity to install activewarning systems at 15% the cost of traditional systems. Such a development would significantly increase the number of crossings equipped with active systems. By leveraging emerging technologies, rail crossing safety may soon be provided at a cost previously thought unthinkable. Minnesota Department of Transportation

Security Measures for Broadband Docsis Cable Modem Communications of Traffic Data
The advent of cable modems conforming to the Data Over Cable System Interface
Specification (DOCSIS) has created an ever-increasing communications infrastructure,
not only for the typical homeowner, but also for the homeowner supporting a Small
Office Home Office (SOHO) and for other small businesses.
The use of DOCSIS cable modems can also be extended to support communications of
traffic data to provide enhancements to existing communications methods. Tests are
currently being conducted at the City of Fort Worth Traffic Management Center (TMC)
using commercial grade and extended temperature grade DOCSIS cable modems to
characterize communications performance parameters and to identify system
constraints.
Whether for the homeowner, the business community, or a TMC, security measures are
vital to ensuring data integrity. This paper will provide an overview of the Community
Antenna Television (CATV) system and the cable network infrastructure. In addition, a
description of the DOCSIS cable modems and how they are being used in a novel
approach to transmit traffic data will be presented. Finally, an overview will be provided
describing the tests being conducted by the City of Fort Worth using the CATV and
DOCSIS cable modems and the security measures that should be considered when
using DOCSIS cable modems within the CATV cable network to provide transmission of
traffic data.

Threshold Acceleration Testing for Crash Detection in Commercial Vehicles
The Federal Motor Carrier Safety Administration (FMCSA) has contracted with the
University at Kentucky and General Dynamics to develop the CVO Safety System, an innovation
that increases commercial vehicle safety and fleet efficiency through the use of on-board
monitoring and reporting technology. This program has developed a brake stroke sensor to
monitor the status of pneumatic brakes and is integrated with automatic vehicle location and
vehicle network communication to help fleet managers assess the safety of their trucks while in
operation. Additionally, the CVO Safety System provides automated crash detection through use of the General Dynamics Crash Detection Algorithm (CDA). Since the CDA was based on
passenger car dynamics, the Algorithm must be modified for use with commercial vehicle
dynamics. The acceleration threshold levels must be set low enough to detect a crash and yet
high enough to prevent false alarms.
