Traffic Congestion Mitigation: A Research Review of Supply and Demand Approaches

As urban areas worldwide continue to reel under recurring congestion, traditional solutions of increasing roadway capacity are falling short in mitigating problem. New or enhanced transport facilities on occasions solves problem in short term, but due to phenomenon of induced traffic it fails to do so in long run. This limitation of supply side improvements is explained using the system dynamics archetype “Shifting the burden” in this paper. A graphical representation is developed to understand the overall effect on traffic conditions in long term because of the supply side solutions. With the understanding of supply side limitations, this paper proceeds with a detailed literature review of demand management approaches. The categorization of Travel Demand Management (TDM) measures explained in the literature review section condenses into a matrix which can serve as a handy tool for cities planning to adopt TDM strategies for congestion mitigation. The limitations of existing TDM approaches are identified, which forms basis for the final section of the paper. In the concluding section, a new approach is proposed where the combination of TDM strategies is advocated with a conceptual flow model. A brief explanation of possible methods that can be used in each step is also discussed.
