Traffic Study

What is the traffic study?

This citywide traffic study will identify traffic flow congestion points along roadways and those within neighborhoods, business districts and school zones. The results will provide deficiencies related to traffic operations and congestion, signal technology and locations with reoccurring accidents. 

How will the input be prioritized?

The input received will be compiled and policy changes will be recommended to enhance safety and traffic flow. These recommendations are short- and long-term solutions to improve the communities overall traffic flow. 

Our city leaders will prioritize the recommendations and develop a strategic plan to implement the improvements.

How can I be involved?

The City of Johnston held a Public Open House for the Johnston City Wide Traffic Study on Thursday, Feb. 16 at 5:30 p.m. This study includes the evaluation of traffic congestion with a focus on the safety and operations of the arterials and intersections across the city. This study will analyze existing conditions, in-person and online public input processes, and the development of suggested improvements.  

The purpose of the meeting was to start the public input process involving city staff and officials, residents, and stakeholders to help us better understand the daily traffic challenges experienced in Johnston.
