Quite a significant number of companies and other large employers have put in place initiatives to address the traffic generated by their activities and, in particular, the traffic generated by their workers and customers. Such Corporate Mobility Management (CMM) initiatives are the focus of this report which provides guidance to governments on effective strategies for addressing and mitigating the traffic generated by commuter and customer travel. The dual focus of the project was to uncover what potential roles, if any, public authorities can play in facilitating the uptake of CMM (see Chapter 3) and to investigate success factors in individual best practice cases at the company level (see Chapter 4). This review was carried out by a consultant (a recognised expert in the field) under the guidance of the JTRC Secretariat and an Advisory Group comprised of 7 countries1. The project builds on the ECMT Round Table “Managing Commuters Behaviour: A New Role for Companies” (Round table 121, 2001) and was partially funded through a grant by Japan.
