Evaluate the onsite three-wheeler parking requirement of supermarket developments to mitigate the parking-related traffic impact in Colombo, Sri Lanka

Parking plays a fundamental role in any transportation system, serving as a crucial element in mitigating traffic congestion and enhancing the overall mobility experience. In Sri Lanka, particularly in commercial and shopping areas within the City of Colombo, the issue of roadside parking has emerged as a significant challenge. This predicament has been exacerbated by the spread of private vehicles, especially three-wheelers, which often operate without dedicated parking spaces despite existing regulations in Sri Lanka. This research endeavours to bridge the divide between the legal requirements, as stipulated by regulations, and the actual operational demand for three-wheeler parking in supermarket areas within Colombo, Sri Lanka. By conducting a meticulous comparative analysis and employing statistical tools like SPSS, the study seeks to provide valuable insights into the onsite three-wheeler parking needs of supermarket developments. The ultimate objective of this research is to establish a standardized framework for allocating three-wheeler parking slots within supermarket areas. This framework aims not only to cater to the existing parking demand but also to alleviate the parking-related traffic issues that currently plague Colombo's commercial and shopping areas. In doing so, this research aspires to contribute to the optimization of urban transportation, making it more efficient and accessible for all road users while also fostering sustainable urban development in the vibrant city of Colombo, Sri Lanka.
