“…If travel fare is charged or checked at the entry point, the passenger boarding rate is much lower than that of alighting. Thus, passenger exchange time is primarily driven by the time required for passengers to enter the vehicle [4,9,19]. In other words, passenger exchange time is determined by the number of individuals entering the vehicle and their average boarding intensity.…”

Original scientific paperIn an urban public transport system, the primary disturbance in the headway arising in the context of departure times has a tendency to propagate through the system. In this paper, by analyzing the movement of vehicles along a specific transport line, the parameters affecting the propagation of the headway disturbance were identified. The established links between these parameters were utilized in the development of a deterministic model. The model describes the propagation of disturbance in the headway by stops along the line, as well as scheduled vehicles at one urban public transport line. The analysis revealed that the number of stops along the line and the passenger boarding intensity have the most significant effect on the propagation of disturbance in the headway. Keywords: deterministic model; dwell time; headway; urban public transport Deterministički model širenja poremećaja intervala slijeđenja vozila na linijama javnog gradskog prijevoza putnikaIzvorni znanstveni članak U sustavu javnog gradskog prijevoza, primarni poremećaj intervala slijeđenja vozila koji nastaje unutar jednog polaska, ima tendenciju širenja u sustavu. U ovom radu analizom procesa kretanja vozila duž linije, identificirani su parametri koji utiču na širenje poremećaja intervala slijeđenja. Na osnovu utvrđenih relacija između parametara formiran je deterministički model. Modelom je predstavljeno širenje poremećaja intervala slijeđenja po stajalištima duž linije i po polascima u voznom redu na jednoj liniji javnog gradskog prijevoza. Analizom je utvrđeno da najznačajniji uticaj na širenje poremećaja intervala slijeđenja vozila u sustavu imaju: broj stajališta i odnos intenziteta nakupljanja putnika i intenziteta ulaska putnika u vozilo.Ključne riječi: deterministički model; interval slijeđenja vozila; javni gradski prijevoz; zadržavanje vozila na stajalištu

“…"Bus bunching takes place when headways between buses are irregular leading to longer waiting times for riders, overcrowding in some buses, low numbers of passengers in the remaining buses, and an overall decrease on the level of service and capacity" (Feng and Figliozzi 2011). For additional information on bus bunching see, e.g., Bellei and Gkoumas (2010). …”

“…Once a bus is behind the schedule, the gap with its leading bus becomes large, leaving more passengers to be picked up at downstream stops, which further delays the bus. Meanwhile, the successive bus collects fewer passengers at stops, which results in less dwelling time, and thus catches up, creating bus bunching; see, e.g., Bellei and Gkoumas (2010).…”

Implementation of an iterative headway-based bus holding strategy with real-time information

In high frequency bus service lines, buses often come irregularly at the stops, often in bunches, due to the uncertainty of the passenger demand and behaviors, and the unexpected conditions on the roads. Vehicle holding is a commonly used strategy among a variety of control strategies in transit operation in order to reduce bus bunching and regulate bus headways. This paper investigates a control strategy of holding a group of buses at a single or multiple control point(s). By incorporating any possible passenger boarding activities during holding, a single control point problem is developed and extended to multiple control points to reduce the variance of headways for the downstream stops. The problem is a non-convex optimization programming with linear constraints that minimizes the total passenger waiting time both on-board and at stops. A heuristic is then developed that is easy and fast to implement, which makes it suitable for real-time implementation. The model is evaluated with a simulation case study by using the real-time bus operation data (i.e., Automatic Vehicle Location and Automatic Passenger Count data) from the Chicago Transit Authority (CTA). The simulation results show that considering the boarding activities in the total waiting time, our model mitigates the error propagation and maintains steady performance, compared to the common models in the literature, which do not consider boarding while holding.
