Impact Analysis of Temporary Traffic Control Design in Planning Construction for Transportation Infrastructure Expansion: The Contractor’s Perspective

In construction of transportation infrastructure expansion or improvement projects, temporary traffic control (TTC) is required to provide enough space for construction. Lane closing and detouring are typical methods often utilized in TTC plans. As the executor of TTC plans, contractors are in need for a relatively easily operated and economical method to conduct impact analysis of alternative TTC plans. Safety, efficiency, and cost of TTC plans are the three main concerns from the perspective of contractors. This paper proposes a framework of TTC plan analysis and modular simulation development to facilitate the impact analysis process for contractors. Statistics from simulation models lends decision support to scheduling, risk control and resource management on transportation infrastructure expansion or improvement projects.
