How to manage the traffic at an intersection?
On an intersection presenting problems of recurring accidents, insufficient capacity related to high traffic flow or with poorly adapted geometry, it will be necessary to install traffic signs, a roundabout, or traffic lights. The choice between a roundabout or traffic lights will be the result of several criteria; essentially the space available and the observed traffic flow.
- Secure a high accident risk zone
- Adapt the intersection according to its geometry or traffic flow
Install vertical and horizontal static sign solutions.
Erect regulatory advance warning LX3 traffic signs as well as developments on the ground:
|LX3 First Sign||LX3 City Sign||Road layout|
Modify the geometry of the intersection
By creating a roundabout and / or by making physical changes to reallocate traffic lanes; islands, chicanes, etc. or by using horizontal marking.
Install a signalized intersection
a. Define the allocation of lanes consistent with the traffic flow into and out of the intersection.
b. Install the corresponding dynamic vertical signs.

c. Install a TRAFFY intersection controller capable of managing all the lines of traffic lights defined in the study.
d. Equip the intersection with appropriate vehicle flow detection systems.
e. Program the intersection controller using the WINTRAFFY software, in order to adjust the duration of the different states of the lights as far as possible according to the actual level of traffic.
