Post-Implementation Evaluation
Construction of the approved King Street Complete Street Project is complete. An evaluation of the corridor has been conducted and provided to the City's Traffic & Parking Board in September 2017. The evaluation included a comparison of traffic volume, speeds and queues with pre-construction data and the results of the project's traffic study. A summary of the evaluation was provided to the City Council in a memorandum from the City Manager.
The evaluation summary highlights final data analysis including;
- Zero reported traffic crashes have occurred in the first year of implementation, compared to an annual average of seven crashes during the 10 years prior to this project.
- Average vehicle speeds on the corridor have been reduced by 18% between Chinquapin Drive and Melrose Street and 4% near T.C. Williams High School (between Radford Street and Chinquapin Drive).
- Traffic delay at the intersection of King Street and Chinquapin Drive has increased in the AM peak hour more than originally anticipated by staff but other intersections along the corridor have seen minimal or no additional changes to delay.
- Post-project studies indicate that traffic diversion onto Scroggins Road has not appeared to increase due to this project, which was an original concern from several residents.

Project Background
The portion of King Street between Janneys Lane and Radford Street was resurfaced in August 2016. As part of that project, the street was evaluated for multimodal improvements. The City hosted three public meetings to solicit feedback from the community about this corridor. The City asked for input on this roadway to get a better understanding of what types of improvements the community would like to see. During and since the first public meeting in November 2015, the community provided the following feedback that staff attempted to address with the new street design options:
- Difficult to cross King Street
- Pedestrian safety concerns near school
- Vehicle speeds along King Street are high
- Street crossings are long
- Not enough time to cross at lights
- Unsafe for people who bike
- Difficult to access bus stops
- Improvements needed at intersections
- Maintain travel time for drivers
- Need to change character of the roadway
Project Goals
- Improve the safety and convenience for all street users
- Provide facilities for people who walk, bike, ride transit or drive cars
- Implement City Council adopted plans and policies
