Synthesis of Information Related to Highway Practices. Topic 55-13. Practices for Operational Traffic Simulation Models

Transportation modeling applications can be divided into two categories: travel demand forecasting and operational modeling. Demand forecasting predicts future traffic volumes for long-term infrastructure investments, while operational modeling focuses on specific problems at a near-term or finer level of detail (such as improving the traffic signal timing along a corridor, identifying the causes of an existing bottleneck, assessing the mobility impacts of a planned construction project, decision making on alternative selection, and more). The tools and methodologies used for the two types of modeling are different, with demand forecasting using macroscopic models and operational modeling using various traffic simulation modeling software. While processes and technical standards for travel demand modeling have been well documented in the previous literature, there is limited information on state departments of transportation (DOTs) practices for operational simulation modeling. The objective of this synthesis project is to document state DOT processes and procedures for operational traffic simulation models.
