Transportation Demand Management (TDM); An Imperative for Tackling Transportation Externalities (A Case of Rumuokoro/East-West Road Intersections) Port Harcourt North, Rivers State Nigeria
Abstract
Transportation, as a derived demand, continuously adjusts itself to respond to the needs and even the wishes of users, which are numerous and diverse. Transportation externalities are unintended by-products of the intended services. The Rumuokoro/East-West Road Roundabout has long constituted a traffic nuisance. Its intended role is catalytic; it should serve as the traffic backbone of the city, facilitating through traffic and strengthening the city’s circulatory system.
A mini traffic survey and reconnaissance conducted support this view. However, this intersection has failed dismally in fulfilling this role, highlighting the need for this paper and the proposed remedial measures for a new direction. Transportation demand management is a global concept with both sophisticated and less sophisticated components. The author realistically proposes adopting less expensive (less sophisticated) measures, which can be affordable given sufficient political will. Minor engineering and non-engineering remedial strategies, at least in the short run, are urgently desirable.
