As Clark County’s population continues to grow toward a half million people, increasing emphasis is placed on managing traffic to safely and efficiently move people and goods.
Public Works often receives requests to have traffic engineers examine a traffic concern on a particular street or location. County residents who want to report a traffic concern should fill out an online request.
Clark County manages traffic only in unincorporated areas outside city limits.
In addition, the county does not manage traffic on federal freeways or state highways, such as Interstate 5 and State Route 500, or on private roads.
Public Works uses emerging technologies to get better performance out of traffic signals, which reduces congestion, greenhouse gas emissions and driver frustration.
Learn more about Clark County’s comprehensive signal program on the traffic signals webpage.
In addition, review the Federal Highway Administration's case study of the Clark County's automated traffic signals performance measures.
Clark County has nearly 100 cameras at signalized intersections, primarily in the urban area outside the city of Vancouver.
County residents may find it helpful to review images from these cameras during morning and afternoon rush hour or inclement weather to determine the best route to their destinations.
For more information, visit the department’s traffic cameras webpage.
Public Works has a policy for traffic control near public and private schools.
The policy is intended to provide guidelines for uniform, consistent traffic control in school zones, including reduced speed zones, signage and beacons, pedestrian crossings and pavement markings.
Clark County, in partnership with DKS Associates, developed this policy based on the Manual on Uniform Traffic Control Devices, Washington state law and sound engineering practice.
The Clark County Pedestrian Crossing Treatment Policy, developed in partnership with HDR, provides guidelines for deciding what type of pedestrian crossing is most suitable for a particular location.
The policy defines “trigger points” to determine appropriate crossing features and how the crossing would best enhance pedestrian safety and mobility.
Public Works also does not enforce speed laws or issue traffic and parking citations. Residents who want information about enforcement should contact the Clark County Sheriff’s Office or call the sheriff's speeding hotline: 360.397.2211 ext. 5482.
Public Works does examine traffic speeds and volumes on specific streets. County residents who want to report a traffic concern should fill out an online request.
Public Works typically does not build speed humps to slow, or “calm,” traffic in neighborhoods. Speed humps are inherently divisive and often pit neighbor against neighbor.
