Analysis of Spatial-Temporal Characteristics of Operations in Public Transport Networks Based on Multisource Data

Journal of Advanced Transportation, 2021
Operational efficiency and stability are two critical aspects to measure bus systems. Influenced by many stochastic factors, buses always suffer from delay and bunching.

Effect of using an in-vehicle smart driving aid on real-world driver performance [PDF]

, 2014
A smart driving system (providing both safety and fuel-efficient driving advice in real time in the vehicle) was evaluated in real-world on-road driving trials to see if any measurable beneficial changes in driving performance would be observed.

Examining the Effects of Visibility and Time Headway on the Takeover Risk during Conditionally Automated Driving

, 2022
The objective of this study is to examine the effects of visibility and time headway on the takeover performance in L3 automated driving. Both non-critical and critical driving scenarios were considered by changing the acceleration value of the leading ...

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.

Study of dynamic headway control bus dispatching rules.

, 1995
The critical criterion for evaluating a bus control strategy is how well it can improve the reliability of bus service. For high-frequency urban bus service, the service reliability is more a function of bus regularity than schedule adherence.
