Traffic Engineering is responsible for engineering studies, plan reviews, and field investigations related to traffic safety, traffic counts, street lighting, school zones, developing school zone ordinances, railroad safety and quiet zones, view obstructions, neighborhood cut-through traffic, speed cushions/humps, as well as requests for additional traffic control devices. The team handles various functions related to system planning and design, as well as the development of transportation projects and general urban design. Traffic Engineering is governed by Chapter 45 of the City Code of Ordinances and Chapters 15 and 17 of the Houston Public Works Infrastructure Design Manual.

Traffic Engineering has three sections:

Traffic Safety: Team develops long-term strategies to reduce traffic deaths and make streets safer and more accessible for all commuters, while also addressing 311 requests submitted by the community.

Traffic Mobility: Team reviews all traffic control, signage, and pavement markings across the city. They work with the Capital Projects team to provide updated pavement markings for Capital Improvement Projects (CIP). This section also manages the Neighborhood Traffic Management Program (NTMP) and speed zones.

Urban Design: Team leads the Design Concept Report (DCR) process for transportation-related capital projects and mobility studies. They provide input for small area planning and design, and streetscape and corridor planning and design.
