In traffic flow, what is the maximum number of cars on a road section where all cars are stopped?

Jam density, also known as saturation density or maximum density, represents the highest possible concentration of vehicles on a roadway, occurring when all vehicles are stationary, either bumper-to-bumper or at their absolute minimum safe and practical spacing. This state signifies that no more vehicles can physically fit onto that s....
