The City of Peoria attempts to coordinate the traffic signals to provide safe and efficient traffic flow throughout the City. The ability to provide good coordination on a corridor is generally a function of signal spacing, prevailing traffic speed, amount of traffic, roadway capacity, signal cycle lengths, and conflicts with other major roadways. Not only does traffic signal coordination serve the greater good of the traveling public, but also has the added benefit of reducing fuel consumption and emissions because it reduces overall traffic delays.
In addition, except for in the Central Business District, most Peoria traffic signals use video or pavement loop detection systems to actuate the signal timing. This allows the signal to adjust the length of a phase of traffic, such as a left turn, to accommodate the current traffic load. This type of system helps clear the intersection and reduce the overall traffic delay. Another benefit of actuated signals is that they allow the controller to know when a vehicle from the side street approaches the intersection, which is particularly important at night because it allows the signals to maintain green signals on the main road and only call for the side street green to be activated when needed.
Are all the traffic signals coordinated?
A majority of the signals in Peoria are coordinated, however, some are not. Signals that are in isolated locations or in too tight of a network do not lend themselves to good coordination. These intersections are often run in a free mode and change on the demand of traffic volumes. In the downtown area, where the streets are laid out in a grid fashion, it has been found that the signals run more efficiently pretimed with short cycle lengths. The downtown intersections are still coordinated on some of the streets that have good progression, however, on other downtown streets, that do not have good progression because of the close proximity of the intersections, they are not coordinated.
Traffic counts, along with various other data, allow the Traffic Engineering Division to make informed decisions whenever we make changes on a particular street. We perform counts so we can get a good idea of what the traffic volumes are for particular streets. All traffic counts are conducted within the City limits.
If there is a concern on your street and you would like Traffic Engineering staff to investigate this concern then contact:
Traffic Engineering Division
If you would like additional traffic count information, you can also visit the getting around Illinois IDOT website.
To report missing or damaged signs, call:
Public Works Dispatch
To request a sign be moved, removed or a new sign installed, call:
- Visit the Public Works - Honorary Street Signs section for more information on Honorary Street Signs.
- Visit the Public Works - Parking section for information regarding On-Street Handicapped Parking Signs.
The City honors State permits for the movement of oversized loads on city streets, but the route must be approved by the Office of the Traffic Engineer.
