, 2018 Bus bunching is the phenomenon of clumping / clustering of buses. Generally buses are scheduled and expected to operate at certain time intervals on a specific route. It is of a natural occurrence that the due to on-road delays and other reasons, the buses deviate from the schedule.

Headway-Based Bus Bunching Prediction Using LSTM with Attention
2023 IEEE 8th International Conference on Intelligent Transportation Engineering (ICITE), 2023Accurately predicting bus bunching during the operation phase can pave the way to improving transit service quality. This paper proposes a Long Short-Term Memory (LSTM) neural network model for predicting bus headway at downstream stops based on ...

Modeling bus bunching using massive location and fare collection data [PDF]
Journal of Intelligent Transportation Systems: Technology, Planning, and Operations, 2019 © 2018, © 2018 Taylor & Francis Group, LLC.Bus bunching is a well-known phenomenon for operators, users and regulators of high-frequency bus services. Bus operations are usually affected by increasing differences in the time intervals (headways) between ...

Bus schedule for optimal bus bunching and waiting times
2018 10th International Conference on Communication Systems & Networks (COMSNETS), 2018In a bus transportation system the time gap between two successive buses is called headway. When the headways are small (high-frequency bus routes), any perturbation (e.g., in the number of passengers using the facility, traffic conditions, etc.) makes the system unstable, and the headway variance tends to increase along the route.

A model of bus bunching under reliability-based passenger arrival patterns [PDF]
Transportation Research Part C: Emerging Technologies, 2015 If bus service departure times are not completely unknown to the passengers, non-uniform passenger arrival patterns can be expected. We propose that passengers decide their arrival time at stops based on a continuous logit model that considers the risk ...

Effects of bunching at stops on bus dwell time
16th International IEEE Conference on Intelligent Transportation Systems (ITSC 2013), 2013Dwell time is an important factor affecting the service capacity of bus route, but the limited capacity of bus stops may lead to the bunching problem which will cause longer dwell time for serving passengers, especially for the corridor with several collinear bus routes.

Dynamic holding control to avoid bus bunching: A multi-agent deep reinforcement learning framework
Transportation Research Part C: Emerging Technologies, 2020Bus bunching has been a long-standing problem that undermines the efficiency and reliability of public transport services. The most popular countermeasure in practice is to introduce static and dynamic holding control.

Understanding the factors that affect the bus bunching events’ duration
2020 IEEE 23rd International Conference on Intelligent Transportation Systems (ITSC), 2020Dealing with bus bunching is a challenge for bus operators, as it strongly affects perception on the level of service provided by buses. Despite the growing interest on bus bunching, existing studies have focused on its frequency, neglecting potential differences in the intensity of bus bunching events and, thus, in the associated effect on passengers.
