“…As for the study of the behavior of pedestrians when giving time priority to public transport, this issue is little researched. As noted by the authors [10], despite a large number of studies on reducing delays at signalized facilities for public transport in general and their passengers, as well as giving time-based priority to buses, there are practically no studies on the impact of giving this type of priority on pedestrian flows at signalized facilities. That is why the authors conducted a study of the delay of pedestrians and passengers at adjacent intersections with those where priority is given to public transport.…”

The paper investigates the improvement of methods of time-based prioritization of public transport buses on city routes, taking into account pedestrian traffic indicators. A method of non-stop passing the stop-lines at signalized intersections and pedestrian crosswalks by buses in places of high generation of pedestrian traffic has been developed. A study was conducted at three signalized intersections and pedestrian crosswalks in Lviv city in places of high generation of pedestrian flows with dedicated lanes for public transport. Pedestrian speed of movement while crossing the roadway in such locations was studied, and the value of the speed of movement of 15% of the pedestrian flow, which potentially will not have time to cross the roadway during the time of the activated permissive signal, was found. The time parameters of extending the restrictive signal for traffic flows for the safe and unobstructed passage of pedestrian flows at the traffic light object are defined. The distance at which public transport should be located from the signalized facility to extend the restrictive signal to public transport, is also determined.

“…Truong presented an advanced transit signal priority (ATSP) control model that considers the arrival distributions of buses at downstream intersections when providing priority at upstream intersections, resulting in an approximate 10% improvement in bus line efficiency [7]. Li reduced the average person delay and improved the traffic efficiency of the trunk line by implementing a signal priority control method based on coordinating green waves [8].…”

Public transportation is a crucial component of urban transportation systems, and improving passenger sharing rates can help alleviate traffic congestion. To enhance the punctuality and supply–demand balance of dedicated buses, we propose a hierarchical multi-objective optimization model to optimize bus guidance speeds and bus operation schedules. Firstly, we present an intelligent decision-making method for bus driving speed based on the mathematical description of bus operation states and the application of the Lagrange multiplier method, which improves the overall punctuality rate of the bus line. Secondly, we propose an optimization method for bus operation schedules that respond to passenger needs by optimizing departure time intervals and station schedules for supply–demand balance. The experiments were conducted in Future Science City, Beijing, China. The results show that the bus line’s punctuality rate has increased to 90.53%, while the retention rate for platform passengers and the intersection stop rate have decreased by 36.22% and 60.93%, respectively. These findings verify the effectiveness and practicality of the proposed hierarchical multi-objective optimization model.

“…In the literature, there are also concepts of allocating priority only in the case of schedule delays [36], sufficient vehicle occupancy [37], the type of line (ordinary or express), or a sufficiently high stopping cost [3,38]. While current technology allows for the easy implementation of such proposals, they often lack substantive justification.…”

Traffic signal priority issues have been a research subject for several decades in Poland and worldwide. Traffic control algorithms have evolved considerably during this period and have become increasingly advanced. Most of them operate within coordinated street sequences, which adds to their complexity. Tramway priority affects traffic conditions for other road users, so many aspects must be taken into account when choosing a priority solution. Typically, one of the main criteria for evaluating the effectiveness of priority is reducing travel time for the priority vehicle while ensuring that the travel times of other traffic participants through the intersection are maintained or slightly deteriorated. However, the energy aspects are often overlooked. This publication aims to investigate how local priority for tramways in traffic signals of coordinated streets affects energy consumption for tramway traction needs. The study was conducted using a microscopic modeling method with PTV Vissim software (ver. 2021). The models were built for coordinated sequences with different levels of priority. Real traffic control algorithms with priority were implemented into the model on the sequence of Marymoncka Street and Grochowska Street in Warsaw. Then, by introducing changes to the parameters of the algorithms, their effect on traffic characteristics, including estimated power consumption, was studied. The results obtained from the computer simulation were statistically processed using R software (ver. 4.3.2). The analysis results prove the effectiveness of tramway priority operation, show its impact on electricity consumption, and allow us to determine the limits of its effective application. Thus, they complement the knowledge of the impact of tramway priority on traffic. The research results also have practical value, as they help us to make rational decisions in the process of designing traffic control algorithms at intersections with a multi-criteria approach.
