Hi guys, I am trying to make a Traffic Simulator for my bachelor thesis. But, I have a problem, I don't know how to keep the correct band of road for every car, all my cars are on the same band of road. I am thinking about the direction between two points and the car will be at the right side of the direction. But I have no idea how to do this.... Thank you!

What is a band? Is that a stretch of road between two points? Or one lane of a multilane road?

Sorry, not the band. The correct side of lanes.

By definition, a lane is for a single line of vehicles. How are sides relevant?

Oh, my mistake, I am very tired. The road has two lanes, left and right. I can create a road with two points, like this: ab The line which is created by the points a and b is midle of the road. Now, I have the point c which is the car în my program. Initial the point is on the line acb If direction of the car (point c) is a>b I whant to put the car in the right lane, and if the direction of the car is b>a I want to put the car in the left lane. Like this: For: a>b  >>>.c For: a<b .c<<< a<b  I know how to put the car on the correct lane, but I don't know when to do it I was thinking about the direction, and to put every time a point to right side of the direction of two points, so my car will be all time on the correct lane of road
