3.2.1	Introduction

To create an accessible built environment, the connection spaces between the various buildings and facilities must also be accessible in order to form a complete travel chain. The travel chain should be continuous such that all users, regardless of their capabilities, can reach their final destination as well as the various points along the way without undue difficulty (3.2.1a).

Connectivity can be achieved by eliminating or mitigating the obstacles found along the travel path. Not only does it entail the provision of accessibility elements such as ramps, lifts, and tactile guide paths, but connectivity also concerns the whole travel experience and it should be looked at holistically at the early stage of a development. Continuity should be maintained throughout the travel journey. The physical pathway, orientation, as well as the sensory effects along the access route should be considered.
