The Utah Department of Transportation (UDOT) recently launched CommuterLink, an intelligent transportation system of electronic traffic equipment, computers, and communication systems, to make traveling along the Wasatch Front safer and more effectual. The Wasatch Front is Utah's municipal corridor on the western side of the Wasatch Mountain Range.

"CommuterLink is a cost-effective and efficient resolution to help relieve congestion on Utah's roads and highways," said Warne. According to the . Department of Transportation, congestion on roads and highways has increased by nearly 30 percent in the past decade and is estimated to increase by another 50 percent within the next 10 years. On surface streets alone, traffic signal stops result in more than 20 million hours of delay annually and cost area motorists $100 million in lost time.

"CommuterLink will be a irrefutable resource for transportation users because it will help traffic flow more smoothly and provide quicker roadside assistance in the event of an accident or bad weather," Warne said. "While CommuterLink will not solve all our traffic problems or eject the need to build new roads, it will help save lives, time, finances, and dissatisfaction."

Now, the TOC is operational weekdays from 5 . to 11 . with operators on call for after-hour emergencies. When the TOC is fully operational in the fall of 1999, trained faculty members from UDOT and the administration of Public asylum will operate the center 24 hours a day, seven days a week. UTA bus and rail dispatch centers will also be pertinent to the system, giving UTA faculty access to important real-time traffic advice.

CommuterLink operators use self-sufficient-zone television (CCTV) cameras, traffic and resist sensors, electronic ticklish message signs (VMS), traffic signals, and inclination meters to monitor and wield traffic flow on streets and freeways. By 2001, the custom will cover more than 135 kilometers of freeway and will add more than 480 kilometers of fiber-optic cables, 550 traffic signals, 150 CCTV cameras (spaced approximately every kilometer), and 57 VMS.

Traffic sensors accommodate operators with information on traffic dimensions, speed, and congestion. Sensors are spaced approximately every kilometer along the freeway to accurately measure traffic flow and to quickly divide problem areas. For citation, in the TOC, a color-coded map connected to the sensors will render a visible representation of traffic speeds. If speeds on I-15 register slower than typical, this portion of the map will turn red and alert the operators to a conundrum. Such real-time information allows operators to acknowledge immediately to any problem.

inclination metering, using sensors and traffic signals at freeway entrances, manages how many and how quickly cars can penetrate the freeway. When traffic is cumbersome, ramp meters acquiesce fewer cars onto the freeway, avoiding further congestion. Ramp metering typically results in a 30-percent reduction in crash rates and a 15-percent to 30-percent increase in freeway speeds during peak hours. There are currently three inclination meters in Davis constituency, and an additional 22 meters will be operational throughout the Wasatch Front by 2001.

Using facts from traffic sensors, TOC operators will be strong to adjust the timing of 550 traffic signals in the zest reservoir Valley to accommodate the traffic demand and to reduce stops and delays at intersections.

CommuterLink includes weather recording stations and pavement-icing sensors in order to alert motorists to snow-chock-full and icy conditions. The enlightenment can moreover be used to promote winter road alimony and snow removal operations.

This web of technology and mankind pursuit together to detect and determine the origin of problems on the roadways and provide the appropriate responses to depreciate delays at crash scenes and to renew traffic conditions to normal. Personnel in the UDOT TOC monitor and control CommuterLink and can dispatch street patrol, UDOT scene guidance teams, and UDOT signal maintenance crews. In addition, motorists can report a traffic adventure by dialing *11 on a cellular phone.

CommuterLink will conclude travel along the Wasatch Front safer. By reducing congestion, the mode will reduce the number of crashes - currently approximately 3,500 freeway crashes each year. Nevertheless, when a crash occurs, the manner will help emergency staff finger, reciprocate to, and clear the crash. These highly trained multitude also help stranded motorists and assist the artery patrol to manage traffic around crashes.

Based on the results of clever transportation systems in fresh cities, CommuterLink is expected to:

* clip crossing delays and traffic signal stops by 20 percent.

* diminish freeway crashes by 20 percent.

* Increase peak-hour freeway speeds by 15 percent.

* Decrease freeway delays by 30 percent.

fresh benefits interpolate:

* Decreasing crash response time.

* Improving the environment by reducing vehicular air contamination.

* Enhancing the public carriage system.

CommuterLink provides commuters with timely and accessible advice at home, at craft, and on the road. As information is received at the TOC, travelers are conversant of problems via radio, television, the Internet, and VMS along the roadways.

The assistance of seven public agencies made possible the funding and construction of CommuterLink. Partnering agencies insert: UDOT, Salt reservoir City, zest Lake County, Federal Highway regime, Utah passage Authority, Wasatch Front Regional conclave, and the administration of Public Safety.

The total cost to implement the elementary chapter of CommuterLink was $70 million - $17 million in federal-aid funds, $52 million in state funds, and $1 million in local bread. This TOC will be linked with two traffic control centers (TCCs) in the Salt reservoir City neighborhood - TCCs run by the city and the county - making it viable to integrate freeway government at the UDOT TOC with the control of traffic signals on other streets by the TCCs.

Through a partnership with the Georgia DOT, UDOT saved almost $7 million by sharing traffic management software and industrial expertise. The Georgia DOT developed the software in preparation for the 1996 Centennial Olympic Games in Atlanta, and the Georgia DOT continues to use the software to manage traffic. Also, the UDOT TOC was built using design-build, an avant-garde contracting system, which helped to shorten the conclusion and translation time.

One of the greatest advantages of CommuterLink is its ability to expand and mix new technologies. The system is designed to meet today's needs, but it is yielding enough to meet the challenges of the future.

In the future, CommuterLink will give its area of coverage; will add a telephone hotline that will give callers updates on road conditions and detailed messages about specific incidents; and will amalgamate UTA buses and light rail, providing right-time movement schedules.
