“…On-street parking manoeuvres can often block traffic for short time causing temporary bottlenecks [43] or sometimes create start-stop traffic flow behaviour on the lanes adjacent to the parking lane [44] and can reduce the road capacity by 20-30% [45]. Some studies have also analysed the impacts of roadside bus stops, which can also disrupt the traffic flow at signalized intersections [46,47]. Buses dwelling at the bus stops to load and unload passengers may occupy a portion of a traffic lane or a bus bay and while moving into or out of the bus stop can block the traffic flow on the adjacent lane, causing excessive delays to the road users and reduction in the capacity of the intersection [13,[48][49][50].…”

The performance of the traffic system can drastically drop when nonrecurrent congestion caused by incidents occurs. Early detection and clearing of traffic incidents will enable the mitigation of the congestion and early restoration of normal traffic conditions. The research in this paper utilized the vehicle information from the recent technological advancement in transportation systems, connected vehicles (CV), and loop-detector information for nonconnected vehicles (NCVs) and developed a novel algorithm to (1) control traffic signals for normal traffic conditions in the absence of incidents, (2) detect traffic incidents using CV/NCV information, and (3) control traffic signals during the occurrence and dissipation of incidents. All the 3 strategies were integrated into one algorithm, which runs as per the real-time traffic conditions, in the presence or absence of incidents. Space-mean speeds of the vehicles on nonincident lanes and throughput maximization criteria were taken as the indicators for the activation of specific signal timings directed at the incident-affected approach. Diverse incident scenarios were tested on a four-legged isolated intersection using the VISSIM simulation tool. Incident detection results showed a higher detection rate and lower mean detection time at higher CV penetration and higher traffic volumes, and at the incident locations nearer to the stop-line. The proposed incident-responsive signal control strategy at 40% and higher CV penetration showed better performance over EPICS adaptive signal control solution, in reducing average travel time delay and the average number of stops per vehicle.

“…In general, the location of bus stops requires special attention when justifying the method of public transport prioritization. Depending on their location relative to intersections and the sections of streets between them, the regularities of delays in the movement of both public and private transport may change [16][17][18]. Based on the analysis of these studies, the location of a stopping point before the intersection is a better solution than after it but only for distances within 70-200 m. Along with this, in the studies [16,17], it is noted that with such a solution the number of delays at the stopping point will be relatively insignificant when the volume of public transport traffic is up to 200 p.c.u./h.…”

Public Transport Prioritization and Descriptive Criteria-Based Urban Sections Classification on Arterial Streets

et al. 2023

The present paper is aimed at improving minimization methods in traffic flows, particularly reducing the costs of civil transportation through sections of the transport network by giving priority to public transport in densely developed areas. In cities with a radial and radial–circular planning scheme of the road network, where arterial traffic flows converge in the central part, the challenge of street congestion with traffic often arises. As a result, delays of all types of vehicles increase, which causes excessive travel time for users of private and public transport. In this regard, it is proposed to divide the sections of the transport network into eight types based on their geometric parameters and traffic conditions. This differentiation of sections improves the existing methods for determining the spatial delay of traffic flows on sections of the transport network with different parameters. It was achieved by considering the duration of vehicles passing signalized intersections and pedestrian crosswalks and the sections of streets between them, while simultaneously recording the duration of public transport movement, as well as the time they spend at stopping points, using GPS receivers. The results of onsite monitoring and further computations revealed that there are particular urban sections with specific, different distances between adjacent stop lines that are critical for public transport operation. Furthermore, based on the delay criterion, there were three different passage modes proposed to improve the efficiency of the traffic.

“…Several features affect the service such as the stop design that has a significant impact on transit vehicle, on the operations of the intersection and its safety as well as the adjacent properties and the system performance (Transit Cooperative Research Program, 1996). The bus stop location, which can be either before near-side or far-side, the design can have an impact on the traffic as some studies have found that the farside stops encounter less overall delays, while the near-side stop may cause more issues (Liu and Jian, 2019).…”

Public transport has always been a structuring factor in urban development and form. Buses, which are one of the essential public services, do not require expensive infrastructure, can be introduced quickly and run as frequently as necessary to meet the demand. Budapest is known by the diversity of its transportation modes and their high frequency, nevertheless, it still faces traffic congestion issues. Thus, the priority granting for the buses is essential to minimize the travel time delays.This research analysis investigates the bus service's situation on the chosen corridor based on personal data collection in peak-hours at the bus stops and on-board using GPS tracker. This research aims to study the dwelling bus’s impact on car delays and targets to optimize the situation by implementing bus priority. The iterative models coded with Octave calculates the vehicles’ delays function of the arrival time and dwelling time of the bus and analyses all scenarios depending on the time the bus is ready to leave the stop and adjusting it by either holding the bus at bus stops or allowing an immediate departure with speed adjustment or green light extension. The objective of the proposed priority model is not only to minimize the bus delays, but also the average vehicle delays on the different branches of the intersection. The prioritization system takes into consideration the non-violation of the maximum holding time, maximum green time extension and maximum red time in the intersection’s branches where the bus stop exists.
