Intelligent Transortation Systems
Frequently Asked Questions

What is ITS?
Intelligent Transportation Systems (ITS) is the application of computers, electronics, communications technologies, and management strategies that reduce congestion and increase safety on the roadways. ITS also provides useful, real-time information on highway and traffic situations.

Why do we need ITS?
As metropolitan areas continue to grow, so do the number of vehicles using the roads. ITS is a means to facilitate the flow of traffic on our roads and reduce travel delays.

Where is ITS being used?
Currently on the major streets of Herndon, Blackstone, Kings Canyon, Willow, and Chestnut.  More streets are being planned or in progress.

What does ITS mean to me?
This means by driving the posted speed limit you reduce the probability of being stopped by a traffic signal.This means means you save gas by reducing the "stop and go" driving. This also means your car will contribute less pollution into the air and helps improve air quality. Lastly, the likely hood of accidents are significantly lessened.

Who pays for ITS?
The City of Fresno, in conjunction with federal, local, and private organizations, funds the ITS projects in the same manner in which new highways are funded and built. In most cases, ITS elements are included in new intersection construction projects.

How does ITS work?
Intelligent Transportation Systems (ITS) are highway traffic monitoring and management systems which use computer, telecommunication, and video technology to help reduce traffic congestion. Traffic-flow data is gathered electronically. The resulting information is used to adjust and synchronize signal timing to provide better traffic flow with reduced delays. The data can also be used to lessen the impact of construction zones and provide information for alternate routes in case of increased congestion.

Can cameras be used by law enforcement to issue tickets?
No. The video cameras run continuously, but the images are not recorded. The cameras are only used to help ITS personnel monitor road conditions that may affect travel.

What streets have ITS?
Herndon, Blackstone,Kings Canyon, Willow, and Chestnut are coordinated. More streets will be timed in the upcoming months.

What speed do I travel to make all the green light?
Generally the speed is 2-3 miles an hour under the posted speed limit.

How often are the average speeds refreshed on the map?
The average speeds shown on the map are refreshed approximately every 5 minutes.

How accurate is construction information?
The most common reason is due to the weather. However, changes could also occur due to the following reasons: 1)work schedules due to equipment malfunction; 2) late material delivery; or 3) other unforeseen circumstances. The list of planned construction reflects the most up-to-date construction plans possible. However, information is most accurate 24 hours before the scheduled start. We suggest you check back close to your departure time for the most accurate construction schedules.

Why are certain devices not working?
The Traffic Operation Center performs routine maintenance on the cameras; however, there will be times when certain cameras or speed information is unavailable. These devices are used by operators at the TOC and these operators will become aware immediately when problems occur.

Why are some left turns after the signal instead of before?
There are two possible reasons for this. First, there may not be enough room to allow cars to turn safely from both directions at the same time. Second, the intersection is most likely a non standard distance away from another intersection. This makes a lead-lag left turn necessary for timing both directions of traffic.

Why are the left turn lights so long?
The length of the left turn light is set for the anticipated traffic level. Other timing issues may also come into play.

Why does the "Don't Walk" light start to flash red so soon?
The "Walk" sign is designed to allow pedestrians to enter the intersection. By the time the "Don't Walk" sign starts to flash, all crossing pedestrians should have stepped off the curb. The pedestrians should have enough time to safely cross the intersection.

Does ITS increase the capacity of the Roadway?
No. ITS does not increase a roadways capacity, but it does increase it efficiency.
