| Title of the article | The speed of cars at the exit from the urban high-speed roads |
| Abstract. | Due to the high cost of land plots in the largest cities of the Russian Federation, the withdrawal of urban territories for the construction of high-speed main urban roads is not always economically feasible. It leads to the need to find reasonable solutions, including for the individual purpose of geometric parameters of transitional high-speed acceleration and braking lanes, depending on the construction conditions, taking into account urban planning limitations, which requires a number of studies. The aim of the study is to improve the design quality of transitional high-speed braking lanes on main urban high-speed roads in the largest cities of the Russian Federation. The objectives of the study are to measure the speed of the cars changing lanes which leave the main urban high-speed roads to the transitional high-speed lane at the moment they cross the marking line, depending on the length of the transitional high-speed lanes and movement comfort level, and also identifying patterns of influence of the length of the transition-speed lane and the level of ease of movement on the speed of lane change. Experimental studies were conducted using a radar speed meter on sections of traffic flow separation on the Moscow road network. The results of the studies show that with a decrease in the level of traffic convenience, the speed of lane change to the transition-speed lane will decrease. With an increase in the length of the transition-speed lane, the speed of cars increases when changing from the right lane of the main city roads of high-speed traffic to the transition-speed lane. The authors also proposed a traffic organization scheme that allows reducing the area of the built-up territory during the construction of transition-speed deceleration lanes. The studied values can be used to justify a decrease in the length of transition-speed lanes in case of urban planning restrictions that do not allow adhering to standard values. |
