Project Overview

The Tigard Neighborhood Traffic Management Plan will focus on identifying neighborhood traffic issues and concerns. The plan will result in a comprehensive, prioritized list of citywide traffic calming projects with concept designs, cost-estimates, and city refinement opportunities. This project will fall under the City of Tigard’s Safe Streets for All (SS4A) Action Plan, which will build off Resolution No. 23-25 to eliminate traffic deaths and serious injuries using a safe systems approach to prioritize transportation safety.

Project Background

Speeding is a significant contributor to roadway deaths and is particularly hazardous to pedestrians. In line with the safe systems approach, Tigard recently implemented a 20 is Plenty program reducing neighborhood speed limits from 25 to 20 mph. The combination of a reduction in regulatory speeds and traffic calming improvements will promote safety and livability in residential neighborhoods.

Traffic calming refers to a set of design interventions aimed at slowing or diverting car traffic to improve safety for all road users. Traffic calming supports the livability and vitality of an area by improving non-motorist safety, mobility, and comfort. It encourages more responsible driving and can potentially reduce traffic flow.

• Safety: By reducing vehicle speeds and volumes, traffic calming measures significantly decrease the likelihood and severity of collisions.
• Quality of Life: Traffic calming can enhance the quality of life in a neighborhood by reducing noise and air pollution from vehicles.
• Active Transportation: Slower traffic speeds make streets safer for walking and biking, which encourages healthier modes of transportation.
• Environmental Impact: Encouraging active transportation can reduce the carbon footprint of transportation, contributing to environmental sustainability.

Traffic Calming

Traffic calming can be achieved by horizontal deflection, vertical deflection, street width reduction, routing restriction, or feedback signs and beacons, to cause motorists to slow down and navigate safely. The project team will be looking for feedback on the following traffic calming measures:
