Finding Causes of Irregular Headways Integrating Data Mining and AHP
ISPRS International Journal of Geo-Information, 2015 Irregular headways could reduce the public transit service level heavily. Finding out the exact causes of irregular headways will greatly help to develop efficient strategies aiming to improve transit service quality.

Application of modular vehicle technology to mitigate bus bunching
Transportation Research Part C: Emerging Technologies, 2023 The stochastic nature of public transport systems leads to headway variability and bus bunching, causing both operator and passenger cost to increase significantly. Traditional strategies to counter bus bunching, including bus-holding, stop-skipping, and bus substitution/insertion, suffer from trade-offs and shortcomings.

A Real-Time Control Strategy for Bus Operation to Alleviate Bus Bunching
Sustainability, 2022 In order to alleviate bus bunching and improve the balance and punctuality rate of bus operation, a single-line real-time control strategy based on Intelligent Transportation System (ITS) was proposed. The strategy took three measures: controlling the cruising speed, dwell time, and the bus load rate to improve the stability of bus operations and to ...

Reducing Bus Bunching with Asynchronous Multi-Agent Reinforcement Learning [PDF]
Proceedings of the Thirtieth International Joint Conference on Artificial Intelligence, 2021 The bus system is a critical component of sustainable urban transportation. However, due to the significant uncertainties in passenger demand and traffic conditions, bus operation is unstable in nature and bus bunching has become a common phenomenon that undermines the reliability and efficiency of bus services.

Comparison of Two Algorithms for Multiline Bus Dynamic Dispatching
Discrete Dynamics in Nature and Society, 2022 Dynamic bus scheduling refers to adjusting the departure time according to the latest time-varying information or adjusting bus speed in the process of operation. These control strategies can prevent bus bunching and alleviate traffic pressure. The paper

Improving Bus Operations through Integrated Dynamic Holding Control and Schedule Optimization
Journal of Advanced Transportation, 2018 Bus bunching can lead to unreliable bus services if not controlled properly. Passengers will suffer from the uncertainty of travel time and the excessive waiting time. Existing dynamic holding strategies to address bus bunching have two major limitations.
