Overview

Rapid Road Transport (RRT) develops new methodologies for the strategic planning, operations control and road infrastructure developments for the DART system as an innovative and feasibility-based mobility concept. RRT also aims to integrate the DART system into Singapore’s flexible-and fixed-route bus systems, MRT/LRT systems, and emerging shared mobility systems. RRT identifies suitable use cases of the DART system and guarantees a reliable and high quality of service in order to make it preferable for passengers. The long-term objective of RRT is to develop theoretical-, simulation- and empirical-based research to support the DART system as a fully flexible mobility concept.
