Traffic operations analysis bridges the gap between transportation planning and traffic engineering and design. CHS senior transportation planners and traffic engineers have over 25 years experience in analyzing traffic operations in saturated urban environments to develop realistic solutions to complex traffic problems.

CHS transportation planners and engineers use state-of-the-art microscopic computer simulation software such as Transyt, Synchro, CORSIM, and VISSIM to perform traffic operations and traffic simulation analyses. These software programs provide animated visual presentations of how traffic flows and how queues form and dissipate. CHS staff present recommendations to the general public and decision-makers to better inform them of the impacts and benefits of various transportation solutions.
