“…The current issue and full text archive of this journal is available on Emerald Insight at: https://www.emerald.com/insight/2399-9802.htm two classes: scheduled-based method (Steiner and Irnich, 2018;Kumar et al, 2019;Chen and Sun, 2019) and headwaybased method (Zhang et al, 2020;Gkiotsalitis and Cats, 2018;Zhang and Lo, 2018). In the former group, the control is implemented according to the bus schedules, aiming at improving bus schedule adherence at each station, which is appropriate for low frequency transit lines, whereas headwaybased strategy is designed to keep headway close to the ideal along the route, and this method can be applied to high frequency transit lines.…”

Purpose The purpose of this paper is to develop a dynamic control method to improve bus schedule adherence under connected bus system. Design/methodology/approach The authors developed a dynamic programming model that optimally schedules the bus operating speed at road sections and multiple signal timing plans at intersections to improve bus schedule adherence. First, the bus route was partitioned into three types of sections: stop, road and intersection. Then, transit agencies can control buses in real time based on all collected information; i.e. control bus operating speed on road sections and adjust the signal timing plans through signal controllers to improve the schedule adherence in connected bus environment. Finally, bus punctuality at the downstream stop and the saturation degree deviations of intersections were selected as the evaluation criteria in optimizing signal control plans and bus speeds jointly. Findings An illustrative case study by using a bus rapid transit line in Jinan city was performed to verify the proposed model. It revealed that based on the proposed strategy, the objective value could be reduced by 73.7%, which indicated that the punctuality was highly improved but not to incur excessive congestion for other vehicular traffic. Originality/value In this paper, the authors applied speed guidance and the adjustment of the signal control plans for multiple cycles in advance to improve the scheduled stability; furthermore, the proposed control strategy can reduce the effect on private traffics to the utmost extend.

“…Song [12] used GPS data to obtain the stopping time data of the bus, and used the average stopping time and travel time stability coefficient as indicators to classify the control points into two categories that need to be controlled and can be controlled for a step-by-step solution, with a simple process of local derivation, but the selected solution may not be the overall optimal result. Zhang et al [13] evaluated the performance of control points with different numbers and different distributions through a set of examples, and the results showed that the distribution of control points outweighed the effect produced by their number.…”

In urban bus planning and bus schedule design, reasonably determining the time control points of bus route and compiling points schedule can effectively improve the service level of bus system. According to the six principles of time control points setting, considering the influence of POI factors near the station on time control points selection, this paper establishes the average number of bus boarding, standard deviation rate of bus headway, standard deviation rate of running time between stations, importance of POI around the station and station dispersion index, proposes the technical process of scheme preference, and designs a comprehensive evaluation function for time control points selection. Thus, the control point scheme selection is carried out. In the study, the proposed time control points selection method was applied to the bus route 700 in Xi'an, taking the APTS data and POI data of the bus route for one week as an example, and the study showed that the method can be applied to the actual bus operation management, which can provide scientific decision-making basis for urban bus planning and design.

“…One of these options is to increase the number of PT trip by increasing the speed of communication and reducing the time delays when crossing intersections. This can be achieved through the creation of lanes for PT and the introduction of the crossing intersections priority for PT [5]- [7].…”

In recent years, the Russian Federation cities have been actively implementing the concept of "priority for the development of public transport". The most common measure for the implementation public transport priority in Russian Federation is the organization of dedicated lanes. Most often, lanes for public transport are created by reducing the number of lanes for cars and trucks. This method effectiveness is well studied, and it is also known that this measure leads to deterioration in traffic parameters for private vehicles. The article discusses an alternative variant of the public transport priority on intersections with the use of traffic light adaptive control. The analysis of the advantages and disadvantages of two algorithms for adaptive control of traffic light objects is carried out according to the criterion of reducing the delay time of public transport when driving through intersections. With the help of imitation micromodeling, the dependence the delay time on the traffic intensity at a separate intersection was established for the basic variant, the variant with a lane for public transport, two variants of the active priority and the combined variant "active + passive" priority. For all variants, a comparative assessment was made of the deterioration of the driving parameters for personal cars and the improvement for public transport. The methods of granting the public transport priority were ranked according to the criterion of efficiency (travel time delay) for vehicles and all transport system users (drivers and passengers). It was found that in terms of average user travel time delay, passive priority reduces delay by 11.2% on average across the board. Using the combined method (active + passive) reduces user travel time delay by 17.1%. Also, using the combined method reduces the negative effect on personal vehicles compared to passive ones.
