Traffic Safety Input

DDOT is committed to making District streets safer for all roadway users while providing multimodal mobility and access for residents, visitors, and commercial users. A combination of traffic control devices and traffic calming measures can help meet both goals. DDOT has a full portfolio of proactive, data-based safety efforts, which can be reviewed at https://visionzero.dc.gov/pages/engineering. In addition, our Traffic Safety Input (TSI) program provides a mechanism for DDOT to hear from residents on roadway segments and intersections where users have safety concerns. 

Residents should not request maintenance of existing assets through the Traffic Safety Input program; instead, please use the appropriate 311 categories (e.g. Roadway Signs, Roadway Striping/Markings, Sidewalk Repair, Traffic Signal Issue). Maintenance requests submitted as Traffic Safety Inputs will not be addressed.

A Traffic Safety Input can be submitted via 311 by a resident, ANC, or other community member or organization and will be prioritized based on objective factors such as roadway characteristics, crash patterns, equity, proximity to Vision Zero High Injury Network corridors, and locations utilized by vulnerable road users such as schools, Metro rails stations, and bus stops. Based on these factors, DDOT’s Traffic Safety Branch will develop a work plan for 800 prioritized locations per year (200 each quarter) to evaluate the safety concerns expressed and determine if any action is needed. All TSI submissions that are not included in the quarterly work plan will remain in the system for prioritization in following quarters. 

The Traffic Safety Input (TSI) Dashboard tracks the process from start to finish for prioritized TSI locations. Many of the TSI requests are complex and require review, data collection, site visits, or other actions as part of the evaluation. DDOT tracks each step to ensure residents can follow the progress of prioritized TSIs.
