The critical points on the rail and road network are their intersections, i.e., level crossings. During a train crossing, car traffic is stopped. This reduces the fluidity of traffic on the road and, consequently, can cause congestion. The problem increases with the number of cars and trains. Frequently, due to national regulations, level crossing closure times are long. It is mainly dictated by safety issues. Building two-level intersections is not always a good solution, mainly because of the high cost of implementation. In the article, the authors proposed the use of sensors to reduce level crossing closure times and improve the Level of Service on the road network. The analyzed railroad lines are local agglomeration lines, mainly due to safety (low speed of commuter trains) and high impact on the road network. The sensors proposed in the article are based on radar/LIDAR. Formulas similar to HCM methods are proposed, which can be implemented in a railroad crossing controller. Simulations using the PTV Vissim program are carried out and the results are worked out based on the obtained data. The considered method can reduce the level crossing closure time by 68.6%, thereby increasing the Level of Service on roads near railroads.
铁路和公路网络上的关键点是它们的交叉点，即平交道口。火车通过时，汽车交通会停止。这降低了道路上交通的流动性，进而可能导致拥堵。随着汽车和火车数量的增加，这个问题愈发严重。通常，由于国家规定，平交道口的关闭时间很长，这主要是出于安全问题的考虑。建造两层交叉路口并不总是一个好的解决方案，主要是因为实施成本高昂。在本文中，作者提出使用传感器来减少平交道口的关闭时间，并提高道路网络的服务水平。所分析的铁路线是地方集聚线，主要是出于安全原因（通勤列车速度较低）以及对道路网络的影响较大。本文提出的传感器基于雷达/激光雷达。提出了类似于公路容量手册（HCM）方法的公式，可在铁路道口控制器中实现。使用PTV Vissim程序进行了模拟，并根据获得的数据得出结果。所考虑的方法可将平交道口的关闭时间减少68.6%，从而提高铁路附近道路的服务水平。
