Factors influencing the collision of cars moving one after another

Abstract

The cars that make up the traffic stream are different. In the streets of the city, the traffic stream consists mainly of cars, trucks and buses. The number of other transport vehicles in the traffic stream is insignificant, so they can be ignored in the calculations. Cars getting into a queue move one after another in a random manner. As this takes place, there are several cases: a passenger car moves behind a passenger car; a lorry moves behind a passenger car; an bus follows a passenger car; a passenger car follows a truck; a truck moves after a truck; a bus moves after a truck; a passenger car is moving behind a bus. A truck follows a bus, a bus follows a bus. Inadvertent queuing of cars in case of a traffic accident (RTA) is of great importance for determining the braking distance of the car, for different cars have different dimensions and designs. When studying collisions of cars in a uniform and uneven distribution of cars in the traffic stream, the braking distance of the car must be taken into account. The brake signal of the front vehicle in the traffic stream is activated only after the reaction time of the driver of the front vehicle. That is why the braking of the rear car takes some time. The time required to stop the rear vehicle will be equal to the sum of the reaction and braking time of the front vehicles and the response time of the braking, as the driver of the rear vehicle receives information as to the braking of the front vehicle only after the front vehicle's braking signal is activated. Most of these cases end in a car collision. Taking into account the situations to prevent accidents in the traffic stream, it is possible to determine the optimal distance between the cars moving one after another. This will make it possible to avoid a rear-end collision with emergency braking of the front car
