Multimodality is the usage of several modes during a trip. A multimodal transport hub is a location where passengers transfer from one mode to another and facilitate the following functions: • The act of changing between modes - interchange • The place where one changes between modes - interchange zone • A purpose-built facility to improve interchange quality - interchange facility [1] Kadawatha is a suburban town centre which is located 16 km away from the centre of Colombo in Gampaha District. Kadawatha city area is located in the Pahala Karagahamuna East, Pahala Karagahamuna North, Pahala Biyanwila East and Ihala Biyanwila North Grama Niladhari Divisions. Mahara Pradeshiya Sabha and Biyagama Pradeshiya Sabha are the administrative authorities of the Kadawatha town area. Ganemulla, Mahara, Kirillawala, Ranmuthugala, Dalupitiya, Karagahamuna (upper and lower), Biyanwila (upper and lower) and Kirimatiyagaraya are the smaller town centres surrounding Kadawatha. There are some major problems in the existing Kadawatha bus terminal such as poor linkage with the main town centre and inadequate luxury facilities for passengers using expressway buses. Moreover, bus services to Ganemulla and Ragama terminate before reaching the town centre, the express and other regional services operating on the Kandy Road also do not touch the terminal due to such buses not using the by-pass. Absence of direct bus connections to destinations having high passenger demand such as Wattala, Weliweriya is also a notable shortcoming.
