Presenter – Dr Bobby Du & Paul-Antonin Dublanche

DR BOBBY DU BIO

Dr Bobby Du is currently a Lecturer and Course Coordinator at the SMART Infrastructure Facility.

Dr Du is responsible for transport modelling and relevant data analysis to support researchers and projects.

His research interests focus on better understanding people’s travel behaviour and practically improving transport systems using modelling, optimisation, simulation and data analytics tools.

PAUL-ANTONIN DUBLANCHE BIO

Paul-Antonin Dublanche is a first year Master student in applied Mathematics from France, and he is taking a 3-month SMART Internship under Dr. Bobby Du.

Paul has strong skill and interest in mathematical modelling and data mining. In his internship, he tries to visualize where and when bus bunching appears in order to find the causes, and then some solutions.

Is bus bunching serious in Sydney?
Preliminary findings based on Opal card data analysis

Abstract

An efficient and reliable public transit system plays an important role in mitigation of congestion and attraction of more users from private car. However, sophisticated traffic conditions and dynamic travel demands often make public transit services unstable and uncertain, which results in longer waiting time especially during peak hours or special events.

One common phenomenon called bus bunching or platooning usually happens when the headway between successive buses arriving at the same bus stop is less than the scheduled headway or a certain threshold. Bus bunching is a major source of congestion, which not only causes passengers delayed travel time and extra waiting time, but also degrades the bus operation performance.

To tackle the bus bunching issue, three questions need to be answered: When and where does bus bunching happen? Why does bus bunching happen? How to reduce or avoid bus bunching? In this seminar, some findings from our preliminary work based on Opal card data analysis will be shown to answer the first question. In the following work, we will try to answer the remaining two questions by exploring the reasons behind bus bunching and designing the corresponding solution strategies.
