Transportation plays an important role in the economic growth and development of a country because a good and efficient transport network facilitates the movement of goods, services and people. As such, understanding traveller’s travelling behaviour, particularly traveller’s day-to-day routing adjustment behaviour is crucial in helping relevant stakeholders plan, implement and manage an efficient and inter-connected transport network. This study aims to investigate the day-to-day routing adjustment behaviour of public bus transport users in Singapore, in the event of transport network changes, for example, when a new link is added, or when an existing link is disrupted. In the event of changes to the transport network, travellers will alter their routing choices and eventually reach a new equilibrium. The main methodology used in this research project is survey study, with the survey consisting of four sections. The first section aimed to collect the basic demographics of the survey respondents, mainly the gender, age and occupation. The next section investigated the travel behaviour of the respondents, asking if and how frequent the respondents commute via the public bus. The willingness to switch their travel route when their existing travel route is disrupted and when there is a new link to get to their destination were also recorded. Respondents were also asked to rank the factors they consider when deciding which bus service to use in their commute. The third section consisted of a scenario-based question where respondents were asked if they would switch to a new bus service which reduces their travel time by 5-10 minutes but will incur a higher cost, together with some other factors that are proposed to affect their travelling behaviour. The last section was a case study on the newly opened Lornie Highway, which was a case of a new link being added, respondents who used this link in their commute had their adjustment travelling behaviour recorded.
