Modeling & Simulation

KAI applies state-of-the-practice techniques and technology in the area of integrated modeling, including regional travel demand modeling, mesoscopic dynamic traffic assignment, microscopic simulation, and greenhouse gas emissions modeling. Good modeling and traffic analysis begins with a solid understanding of a project’s needs and the use of the most cost-effective and appropriate tools available.

KAI staff understands the steps, strengths, limitations, inputs and outputs, and direct import/export capabilities of transportation simulation models to maximize the effectiveness of these complex tools. A wealth of staff experience allows KAI to apply the right simulation modeling tool at the right level, resulting in time savings and reduced costs. Key members of KAI staff have extensive experience applying many of these models to projects for both public and private clients internationally.

KAI staff is proficient in the use of modeling analysis tools such as Cube, TransCAD, EMME, VISUM, Dynus-T, DynaMEQ, CORSIM, SIMTRAFFIC, Paramics, and VISSIM. KAI has authored national guidebooks for the Federal Highway Administration, including the Traffic Analysis Toolbox Volumes III: Guidelines for Applying Traffic Microsimulation Software, and Effective Integration of Analysis, Modeling, and Simulation (AMS) Tools. KAI has been a leader in advancing integrated modeling techniques to evaluate network traffic operations. On behalf of FHWA, KAI worked with a research team to develop a data hub for integrated modeling applications and developed enhancements to an open-source Dynamic Traffic Assignment software tool to evaluate safety and pricing strategies.
