Traffic Sign

Overview

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.

What began as a two-lane arterial street is now a beautiful multi-modal scenic corridor lined with California Pepper Trees and iconic three-rail white fencing, a Complete Street with traffic calming elements, landscaped center medians, enhanced bike lanes, two pedestrian/equestrian crossings, an equestrian bridle trail and wide pedestrian path. Before and after studies have shown that bike traffic has doubled and traffic congestion has declined. More joggers, school children and beginning bicyclists are using the off-street paths. Traffic speeds have fallen, making active transportation choices more inviting.

for the widening of 1.3 miles of roadway, 5-foot bike lanes within a 200-foot right-of-way, a second through lane at major intersections, raised medians, street resurfacing and traffic signal modifications.  In addition, Willdan Engineering provided utility coordination/relocation, geotechnical engineering and testing,  federal funding administration; environmental clearance (NEPA and CEQA); contract administration and construction inspection.
