Mobility service integrated multimodal transportation system provides a seamless and convenient travel solution to improve the current public transportation services in the tourism sector. This innovative approach can decrease the reliance on private vehicles among tourists traveling to destinations in developing countries like India. Before the implementation of any new service, it is essential to identify the key attributes that tourists value when choosing a particular mode of travel for their destination. This study investigates mode choice preference among current modes and integrated public transportation services for choice riders during their future leisure trips in the Calicut and Wayanad districts of Kerala using a stated preference survey. The attributes found to influence tourist mode choice are travel time, waiting time, travel cost, service hours, crowding, safety and security, and travel information. Multinomial logit model (MNL) model was developed for auto rickshaw integrated bus service (ARIBS) and bike taxi integrated bus service (BTIBS) in the case of private car respondents. Derived willingness to pay (WTP) values are higher for crowding level, safety and security, travel information, and travel time. The findings are important in policy formulation for the implantation of integrated multimodal public transportation services for tourists.
