Willdan specializes in providing traffic engineering and planning services to governmental agencies. Our services range from responding to citizen complaints to designing and managing multimillion dollar capital improvement projects.
Currently our staff serve as contract City Traffic Engineers or provide traffic engineering services for approximately 40 cities in the Southwest.
Our front-line knowledge and understanding of local road and traffic conditions are the cornerstone of our services. Willdan’s traffic engineering staff applies state-of-the-art concepts to confirm the adequacy of transportation facilities, to determine the need for traffic control devices, and to ensure the safe and efficient operation of the transportation system.
Our staff of experts conducts traffic surveys and data collection, investigates motorist and vehicle characteristics—identifying and making recommendations on traffic safety, utilizes traffic laws and enforcement to determine traffic signal timing, and evaluates highway operations. Willdan prepares traffic engineering designs to warn, regulate, and guide traffic. We develop geometric design and channelization, traffic signal and street lighting plans, parking lot designs, and develop traffic control plans for construction.
