The use of signs, traffic signals or crosswalks at intersections play a big part of ensuring motorist and pedestrian safety. Using input from residents and collected data, the Transportation division will assess and determine if any of these traffic management tools are required at a specific location.
If you think your neighbourhood would benefit from the addition of a stop sign, traffic lights or a pedestrian cross walk, please call the Transportation Division directly.
Where there are no traffic control signs, the driver of a vehicle approaching an intersection must yield the right-of-way to any vehicle or pedestrian already in the intersection. When two vehicles approach an intersection from different streets or highways at approximately the same time, the right-of-way rule requires the driver of the vehicle on the left to yield the right-of-way to the vehicle on the right.
The City will employ the least restrictive control device possible, to achieve the desired results and safety. Where the right-of-way rule does not suffice, YIELD or STOP signs are used where traffic engineering studies indicate that the use is warranted. Factors considered are:
- Vehicular, bicycle, and pedestrian traffic volumes on all approaches
- Number and angle of approaches
- Approach speeds
- Sight distance available on each approach
- Reported collision experience
YIELD or STOP signs are usually used at an intersection if one or more of the following conditions exist:
- An intersection of a less important road with a main road
- A street entering a designated through highway or street
- An unsignalized intersection in a signalized area.
At intersections where a full stop is not necessary at all times, consideration is first given to using less restrictive measures such as yeild signs. The yield sign indicates to drivers that they must yield the right of way, stopping if necessary, before entering the intersection area and must not proceed until it is safe to do so.
The stop sign indicates to drivers that they must stop their vehicles completely before entering the intersection area and must not proceed until it is safe to do so.
Multi-way stop control is typically used where the volume of traffic on the intersecting roads is approximately equal.
Traffic signals promote the proper use of right-of-way at intersections and contribute to the safe movement of vehicles and pedestrians.
The Transportation Division is responsible for assessing, co-ordinating, installing, operating and maintaining nearly 275 signalized intersections in Saskatoon. More than half of the traffic signals in Saskatoon are controlled by a centralized computer for real-time monitoring.
Several issues are considered when determining if an intersection should have traffic signals including:
- Vehicle and pedestrian volumes on the main street and side street(s)
- Collision history
- Traffic and roadway characteristics, such as vehicle speed and traffic delays
- Intersection lane configuration, sight lines and grades
Many signalized intersections in Saskatoon have vehicle detectors located at the stop lines on side-streets which activate the green light. If you waited an excessively long time without receiving a green light, it is likely that your vehicle was not seen by the detector. Be sure to stop at the stop line to ensure that your vehicle is detected by the sensors.
A left-turn arrow typically comes on when a vehicle detector determines there is a miniumum of four to five vehicles in a turning lane. Otherwise, it is generally assumed one to three vehicles will be able to turn left on the solid green when adequate gaps appear in the oncoming traffic, and/or will clear the intersection during the amber/red light.
