Rapid urbanisation and industrialisation are driving employment opportunities for all categories of people. Due to land availability constraints and the high cost of settling near industrial regions and urban hotspots, working professionals are often compelled to settle on the outskirts of urban centers where the cost of living is lower. Consequently, these professionals must commute from their residences to their workplaces, typically relying on private transportation, which has a significant negative impact on the environment and traffic congestion. To mitigate these issues and promote sustainable commuting, infrastructure enhancements are being developed to encourage the use of public transport. The main objective of this study is to understand the dynamics of mode choice and develop a behavioural model for working professionals in response to these infrastructure enhancements. Focusing on Info Park in Kakkanad, Ernakulam, data was collected through a stated preference questionnaire survey targeting working professionals. The findings indicate that as income rises, people show a stronger preference for cars and two-wheelers over public transportation. However, commuters’ willingness to switch to the metro and water metro increases when the cost of these options is reduced. This study provides stakeholders with valuable insights into the feasibility of infrastructure enhancements and informs the development of policies to effectively encourage the use of public transport, reducing reliance on private vehicles and alleviating urban transportation challenges.
