The Traffic Management Branch is responsible for performing engineering studies, plan reviews, & field investigations related to traffic safety, traffic counts, street lighting, school zones, speed humps, railroad safety & quiet zones, view obstructions, neighborhood cut-through traffic, and Capital Improvement Plan (CIP) projects. This branch also manages street and lane closure permits, develops general speed & school zone ordinances, and coordinates with HPD to help alleviate traffic congestion hot spots under the Mobility Response Team (MRT). Additionally, the Traffic Management Branch performs various functions relating to system operations, including signal design, modifications & timing, and Intelligent Transportation System (ITS) development. The branch is governed by Chapter 15 of the Department of Public Works & Engineering's Infrastructure Design Manual.
Michael Wahl, P.E., PTOE - Supervising Engineer
Responsible for in-house Intelligent Transportation Systems (ITS) and traffic signal design, School Zone flasher operations, project management, and coordination with H-GAC on Capital Improvement Projects. ITS & Operations Safety consists of engineers, project managers, analysts, and construction inspectors.
This section oversees various transportation related programs, including:
Congestion Mitigation and Air Quality (CMAQ) Program
Quiet Zones Program
Railroad Safety Program
School Coordination Program (applications/ investigations/ approvals for adding & removing school zones & related infrastructure)
Street Lighting Program (applications/ investigations/ plan reviews)
Kerry Parker – Senior Project Manager
Oversees Lane & Street Closures, Sidewalk Closures, and Sidewalk Cafés, and Curb Painting.
The mobility permit system portal provides the City of Houston with the ability to manage city streets and sidewalks during public and private construction. If you are a contractor that may require temporary use of city streets or sidewalks during construction, please read our FAQ prior to applying for a permit. The mobility permit portal also serves to manage sidewalk café permits.

Gary Drabek – Senior Staff Analyst
Oversees applications/ investigations/ approvals for the Neighborhood Traffic Management Program (NTMP), which utilizes traffic calming measures along residential streets with excessive vehicular speeds and cut-through traffic.
T. Rebagay, P.E. - Supervising Engineer
Reviews all construction plans from a traffic engineering perspective, such as the need for traffic signs, pavements markings, and traffic control. This section also provides plan review for relevant Capital Improvement Projects.
Gerald Wilson, P.E. - Supervising Engineer
Responsible for various traffic safety initiatives, including the safety prioritation of signalized intersections, non-signalized intersections, and midblock locations, as well as proposing countermeasures for prioritized locations. Countermeasures include upgrades to signing, pavement markings, signal operation, intersection design, etc.
This section also examines improvements to pedestrian safety, conducts speed surveys and traffic count studies (including Turning Movement Counts and Average Daily Traffic, or ADT), and coordinates with various entities on relevant Capital Improvement Projects.
Johana E. Clark, P.E., PTOE - Supervising Engineer
Oversees all traffic signal operations within the City, including those along TxDOT facilities. Signal Operations responds to citizen complaints over signal timing and requests for new signals and signal modifications such as protected left turn phasing (left turn arrows). This section also assists with plan review for CIP and developer projects, as well as Accessible Pedestrian Device investigations. Signal Operations consists of engineers and senior traffic signal timing technicians. Major projects include the continuation of TSPIP (Traffic Signal Performance Improvement Program) and the development of new traffic signal timing plans for Downtown Houston.
The Mobility Response Team (MRT) is a joint project between the Department of Public Works and Engineering (PWE) and the Houston Police Department (HPD), with the purpose of helping to alleviate traffic congestion. Using resources in place (such as Houston TranStar & 311), PWE staff work with HPD to locate traffic bottlenecks throughout the City. Civilian Mobility Response Officers with HPD are dispatched to provide manual traffic control at congestion hot spots. PWE engineers or technicians are dispatched to evaluate potential improvements in signal timing and operations. While the team's primary focus is inside the loop, they will be available throughout the City. The MRT began full operations on July 1, 2007 and operates throughout the day covering both the morning and evening rush hours (6am – 10pm, Monday through Friday). The MRT's PWE staff is based at Houston Transtar.
Bill Hlavacek, P.E. – Supervising Engineer
Administers various complex engineering studies, including Access Management and review of Signal Warrant Analyses and Traffic Impact Analysis (TIA) reports.
