  Transportation Management

The Colorado Department of Transportation has embarked on an ambitious five-year program to expand and enhance its Intelligent Transportation Systems (ITS) capabilities statewide, focusing on the Colorado Transportation Management Center (CTMC), which is C.D.O.T.’s existing statewide transportation management and traveler information center. The CTMC originated as a continuation of C.D.O.T.’s 1996-98 state-funded Revised Model Deployment Initiative (RMDI), a program that implemented the majority of the system architectures and operating systems currently in place.

C.D.O.T. has been allocated $9 million in FY 1999, Congressionally Designated ITS Earmarks for the I-25 Truck Safety Improvements Project. A 20% match is required, yielding a $2.25 million state funding match and a total federal project cost of $11.25 million. C.D.O.T. and the Federal Highway Association have agreed this funding will be utilized to implement a number of agreed-upon task orders. An additional $14 million of state dollar funding is planned over remaining 4-years for project operations, maintenance, and other statewide integration and deployment projects.

The following is a summary of the task orders (successful to date):

I-25 Truck Safety Reimbursement - This project reimburses C.D.O.T. Region 1 for the ITS elements included in Colorado Project No. IM 0252-038 (truck climbing lanes) from milepost 187 to 194 on I-25 south of the Denver metro area. ITS devices being deployed through this project include VMS, ATR, weigh station, weather monitoring system, and call boxes. The project is under construction with the VMS signs installed at the first phase of the project for additional traffic control.

Port of entry (POE) automation at the following locations: I-25 at Monument, I-25 at Fort Collins, and I-70 at Limon are all federally funded. In addition, partnerships between C.D.O.T. and the Department of Revenue have funded the automation of four additional POEs. These projects have installed devices in the roadway and software at the POEs for weigh-in-motion and/or automated vehicle identification. These series of task orders should be considered a success on the multiple levels of management, teamwork, schedule, and budget. The integrator and its subcontractors, as well as the C.D.O.T. technical manager, are to be commended for successfully completing this work on budget and within a fast-track schedule in spite of front-end delays, which originated from the C.D.O.T.

CTMC Operations - This task order provides technical and administrative staff support at C.D.O.T.’s existing Colorado Transportation Management Center. The task order has been successful although a major point of contention exists regarding the operation of the video manager subsystem; however, the issue should be considered more a part of the Colorado Revised Model Deployment Initiative (RMDI) follow-up work than this task order. The performance of the integrator’s subcontractor providing the personnel has been excellent.

I-25 Interconnect Colorado Springs/Colorado Springs Traffic Signal Interface/Denver Area Traffic Signal Interface - These task orders will provide a communications link between the CTMC and the Colorado Springs Transportation Operations Center, as well as, between the CTMC and Lakewood’s Transportation Operations Center. The traffic signal interface to Colorado Springs and Lakewood will provide an interface to various traffic signal systems to enhance incident management diversion routing. The program/systems manager is completing phase I of these task orders. Completion of phase one has been satisfactory. C.D.O.T. is currently initiating phase two, which includes the exchange of workstations and installation of communications between the centers by C.D.O.T. forces. Future design and implementation stages will be placed on hold pending resolution of how best to complete the CTMS core system.

Highway Advisory Radio (HAR) Redeployment on I-25 - This task order was originally to relocate a number of existing HAR installations from specific locations along I-25 between Denver and the Wyoming border. In spite of the controversy regarding the super-HAR installation in the Denver area, coverage was not close to that depicted in the original engineering study; this task order should be considered a success. C.D.O.T. is credited for the success of this task order. C.D.O.T. proactively investigated alternatives to the proposed reset of four HARs from the Denver area, developed a plan to provide equivalent radio coverage within the budget, and was able to cultivate a previously unlooked-for partnership with the City of Fort Collins. C.D.O.T. And its task manager were complimented on a timely, feasible, and financially workable recovery plan. Alternatives to address the concern of the Super-HAR performance, in the Denver Metro area, are currently being evaluated by C.D.O.T. staff.

I-25 Automated Traffic Recorders - This task order deployed a number of permanent traffic recorders in the I-25 and US-287 corridors south of the Wyoming border.
In spite of long delays and a minor cost overrun, this task order should be considered a success. Through internal partnering, C.D.O.T. was able to obtain one new WIM/ATR in addition to three new ATR (plus the use of a fourth) to assist in data collection. CTMC and Department of Transportation Development will be able to use the data from all the installation, representing a win-win situation for both internal parties.

ITS Maintenance - This task order will allow for preventative, as well as, reactionary maintenance for ITS equipment and subsystems. The maintenance task orders have been a positive and successful experience for both C.D.O.T. And the integrator. A complete inventory of all ITS devices deployed on all Colorado highways has been completed. Now it is essential that ITS maintenance unit focus on keeping an accurate database of repairs and replacement data in order to determine mean time between failures. This information will allow C.D.O.T. to formulate a preventative maintenance schedule based on level of service.
