Overview of Traffic Calming Studies

Simi Valley evaluates requests for traffic calming based on traffic volume, speed data, collision history, and neighborhood support. Typical measures considered include speed humps, curb extensions, traffic circles, signage, and targeted enforcement. The Traffic Engineering or Public Works department manages studies, data collection, and community outreach. For the controlling municipal code and ordinance framework, consult the city code and traffic program pages. Simi Valley Municipal Code[1]
