The influence of the infrastructure of the route network of public transport on the efficiency of road traffic in cities
Abstract
The article examines approaches to evaluating the performance of elements within a city's street-road network, considering economic, safety, and environmental criteria. The main focus is on analyzing various indicators used to assess the street-road network’s operation, such as capacity, average and total vehicle delay, traffic intensity, network density, and capacity. Factors influencing congestion and their correlation with the capacity of individual sections are explored. Emphasis is placed on the necessity of considering these indicators when planning transport infrastructure. Measures aimed at improving both safety and efficiency of traffic are reviewed. The resilience of the city's street-road network and its ability to maintain functionality under changing circumstances are analyzed. An assessment is made of the operating conditions of road network sections, taking into account the impact of public transport stops in the studied area, and the correlation between the design and servicing parameters of the stop points with traffic efficiency indicators is established.
Changes in the service coefficient spent on servicing public transport vehicles at a stop have been determined. This approach takes into account the traffic conditions at the selected location: a street segment with one lane in each direction, additionally featuring a public transport stop located on the roadway. Recommendations have been developed, and critical operating conditions for a typical road section within the city's street-road network have been established. A simulation of the level of service parameter was conducted, considering increases in both overall traffic flow and the intensity of public transport vehicles. The findings will provide recommendations for applying various criteria and indicators to optimize traffic flow management, thereby enhancing the efficiency of the street-road network amid increasing traffic demands.
Key words: street-road network, traffic intensity, public transport, stop point, capacity, traffic control devices, traffic flow.
