Do traffic cameras detect speed?
- Some speed cameras combine with traffic light cameras to monitor lights and junctions too. They can detect vehicles travelling over the stop line or entering the intersection after the lights have turned red. If the speed of the vehicle exceeds the legal limit, or a vehicle runs a red light, the camera is triggered.
Do traffic lights detect speed?

Can a traffic model predict a uniform traffic flow?
- The considered traffic models predict a nice, uniform traffic flow at low traffic densities. However, above a critical threshold density (that depends on the model parameters) the flow becomes unstable, and small perturbations amplify.

What is the difference between traffic flow and traffic volume?
Flow is the rate at which vehicles pass a given point on the roadway, and is normally given in terms of vehicles per hour. The 15-minute volume can be converted to a flow by multiplying the volume by four. If our 15-minute volume were 100 cars, we would report the flow as 400 vehicles per hour.
What should be low speed and high speed for traffic control?
- Typically, low speed is less than 45 mph and high speed is 45mph or greater when determining sign spacing distances. After the traffic control devices are in place, inspection and observation of the work zone needs to take place and adjustments need to be made if there are safety or drivability issues.
