Transportation Impact Statement (TIS)—A New Tool for Transportation and Land-Use Planning

Abstract

This paper advances a new approach to transport and land use planning: the transportation impact statement (TIS). Current planning practice suffers from a lack of understanding of and adequate tools to evaluate the complex relationships that exist between land use and transportation. As a result, land use development often overloads the transportation system. A TIS exposes the complex interdependencies with a multimodal and regional assessment of the impact of land use development on the transport system. The authors offer a theoretical background for this new approach and an empirical illustration of its potential use through a case study based on the city of Haifa, Israel. The aim is to investigate the local and regional transport-related impacts of the proposed land developments, thus improving the planning decisionmaking process. Results show that the total number of trips generated by the proposed land developments is inconsistent with the capacity of the transportation network to accommodate all forecasted demands under all transport scenarios. Implications of these findings are outlined and discussed.
