If you drive in Illinois, chances are that you take advantage of I-Pass to avoid tie-ups at toll plazas. The Illinois Tollway website boasts that "over 2.8 million transponders are taking I-PASS users to their destinations quicker, safer, and easier." I-Pass is a prominent example of ITS, or Intelligent Transportation Systems.
CMAP promotes that use of ITS, including a wide range of technologies that improve the movement of people and goods. The goal of ITS deployment is to improve the efficiency and effectiveness of the transportation system through such actions as increasing traveler safety and reducing congestion. These tools improve the operations and management of our existing transportation facilities. Click here for links describing other examples of ITS.
Northeastern Illinois has been a leader in ITS applications for decades, and CMAP's Advanced Technology Task Force (ATTF) is a strong advocate for ITS applications. The task force has prepared a number of useful resources:
NEW Regional ITS Architecture 2007-2008 Update
Resolution 08-03. The MPO Policy Committee approved the Northeastern Illinois ITS Architecture V.2 on March 13th, 2008. Regional ITS Architecture V.2. This page includes a link to the northeastern Illinois updated Turbo Architecture database (Turbo version 3.1) and to a site providing a free download of the most recent Turbo Architecture (version 4) software. It includes exhibits presenting the contents of the database. Many revisions are pending and will be posted soon.
Regional ITS Plan
Regional ITS Architecture (Legacy)
2002 Regional Architecture. A shared vision of how each agency’s ITS deployments will work together over the next 15 years, sharing information and resources to improve the region’s transportation system.
Examples of ITS
One key element of ITS is the ability to monitor and respond to actual conditions on the transportation system in real time. This performance-based approach allows operators to use the real-time information to identify, respond to and mitigate non-recurring events (such as crashes or weather) that significantly affect the quality of service offered by the system. It also provides the information to travelers that they need to make effective choices, such as time, mode and route of travel. Frequently-encountered examples of ITS projects include:
- I-Pass and open road tolling
- Chicago Card/Chicago Card Plus, an electronic fare collection system used by the CTA, providing faster, cheaper, and more convenient transportation to transit riders
- RTA trip planner provides riders with personalized directions that may utilize both Metra and CTA services, thereby helping web-savvy users get from point A to point B more efficiently and quickly
- Gary-Chicago-Milwaukee Corridor real time information system, providing data and travel information to analysts and the traveling public
- Navteq's traffic.com is a real-time traffic information center with interactive maps and “jam factor” alerts, much of the information resulting from roadside sensors on the system -- which are also ITS projects.
- Pace's Intelligent Bus System and the CTA's Bus Tracker feature AVL/GPS on every bus, Computer Aided Dispatch (CAD) and Schedule/Route Adherence (SRA) information dissemination. This information will soon be available via the Web Watch Project, allowing riders to monitor bus arrivals.
- Traffic signals that change according to the number of cars detected waiting.
- Ramp meters: green and red lights that control how many people access the expressway based on traffic on the expressway.
- Traffic signals with emergency vehicle detection: they turn green to let police, fire and ambulances through the intersections to get help to where it is needed more quickly.
- Intersection red-light running cameras to ticket drivers who run red lights and to make intersections safer.
- Amber alert system (opens PDF) puts messages on variable message screens along highways.
- Message screens on the expressways that indicate current travel time conditions, public safety messages, incidents, construction, etc.
- Reversible lanes equipped with automated lane management technologies, including traffic sensors and lane control signs.
- Automated stop announcements on transit vehicles such as CTA/Pace buses and Metra trains.
- Rail station signs that display automated traveler information (schedule and system information).
- Video surveillance on transit vehicles to enhance security.
- Automatic alerts about the transportation system from IDOT, Pace, and CTA are sent to pagers, PDAs, and email.
