Traffic and Transit

City of Houston Traffic Signal Designs, Houston, Texas
Klotz Associates has completed various traffic signal designs all over the City of Houston. Recently, traffic signals were designed at the intersections of Avenida de la Americas at Dallas and Avenida de la Americas at Walker as part of the George R. Brown Convention Center Expansion project. These intersections required some innovative traffic signal designs which included mounting signal hardware on the superstructure of the convention center.

City of Houston Accelerated Bikeway Program, Houston, Texas

This project was funded through the ISTEA Transportation Enhancement Program.  Klotz Associates was the Program Manager for the City of Houston and managed 16 consultants to expedite 21 separate Hike-and-Bike projects totaling over 77 miles.  Klotz Associates took these projects from conceptual design through the bid and construction phase services.  We expedited the overall process by addressing environmental, right-of-way and PS&E issues simultaneously and engaging the City and TxDOT to streamline the review process.  A cost feasibility study was also performed.  We addressed a variety of issues including drainage, erosion control, environmental impacts, pavement considerations, and security.  Our work for the trails design, bridge structure design, landscape design, and lighting design all met TxDOT, AASHTO, and ADA Standards.  Other services included: coordinating with civic groups and homeowners’ associations, coordinating with area park designs, preparing traffic control plans, and coordinating railroad issues for five Hike-and-Bike trails.

TxDOT East Region Traffic Signal Timing Contract

Klotz Associates will develop traffic signal timing improvements primarily throughout the East Region of TxDOT, and potentially statewide under this two-year contract.  This work includes traffic modeling, signal timing optimization, and timing implementation for signal systems as well as isolated intersections.

TxDOT San Antonio District Transportation On-Call Contract, San Antonio, Texas

Klotz Associates was awarded two consecutive contracts to work with the TxDOT San Antonio District staff to act as an extension of their workforce in public meetings, transportation design, traffic operations, and intelligent transportation system development.  This contract was administered through Work Authorizations that included US 90 bridge assessment and freeway ramp evaluation, Floresville Independent School District roadway / pedestrian assessment, Pat Booker signal timing and geometric improvements, I-410 / US 281 interchange analysis, Destination Signing inventory and improvement assessment, Development of TxDOT’s geographic information system (GIS) database for signing and maintenance, Boerne High School traffic analysis, Various public meetings representing TxDOT San Antonio staff and Pleasanton roadway geometric improvements and traffic operations analysis.

Capital Metropolitan (CAPMETRO) Transit Authority, Crestview Station Transit Access Study, Austin, Texas
Klotz Associates conducted a transit access study for the proposed Crestview Station, which is part of the first commuter rail service offered by CAPMETRO. The study focused on developing conceptual alternatives for improving pedestrian access and multi-modal operations at the N. Lamar Boulevard and Airport Boulevard intersection. We worked closely with CAPMETRO and the City of Austin staff to develop on "opening day transit access" alternative and three long-term alternatives which included detailed intersection improvements, as well as an area-wide circulation concept to complement each intersection alternative.

Houston METRO Solutions UpTown Corridor LRT, Houston, Texas

Klotz Associates provided civil and traffic engineering design for modifications to the Advanced Preliminary Engineering design for Light Rail Transit (LRT) for the UpTown Corridor for Houston METRO's $2 billion METRO Solutions Regional Transit Program. Klotz Associates was responsible for management of several subconsultants for design modifications due to changes in the LRT guideway alignment along Post Oak Boulevard and North Post Oak Road. The modified design was progressed to 65%. The corridor extends from a proposed connection with the University Corridor LRT at Westpark south of US 59 along Post Oak Boulevard through the UpTown / Galleria area to the Northwest Transit Center at IH 610 and IH 10 for a distance of 4.3 miles. Design includes roadway, drainage and traffic design for reconstruction of Post Oak Boulevard from Richmond Avenue to IH 610 including new traffic signals.

Metro Traffic On-Call, Houston, Texas
METRO has awarded Klotz Associates’ Traffic / ITS / Planning group three consecutive on-call contracts and one ITS on-call contract since 2000. Work performed under those contracts has included:

Reviewed six METRO HOV-lane corridors and identified possible locations for freeway guide signing and downtown trailblazer signs on arterial streets; prepared guide sign legends and determined feasibility of locating signs at proposed locations for freeway-to-freeway signing system, including an area-wide schematic; and prepared preliminary estimate of cost.

Performed conversion and / or optimization of existing signal timing for more than 160 intersections on METRO bus routes to Next Phase format; input existing signal timings into the Next Phase database editor for implementation.

Galveston Signal Improvements
The project involved traffic signal design at 40 locations along Seawall Boulevard and Avenues D, E, F, O, and P. The signal improvements were designed to comply with Federal ADA requirements and in accordance with TxDOT and City of Galveston standards and specifications. The project also included preparation of fiber optic communication design plans along Seawall Boulevard, Avenue O, and Avenue P. In addition, development of congestion mitigation measures and optimization of signal timing plans were conducted along Seawall Boulevard. The construction budget for these improvements was approximately $4,000,000 and the design was completed over a period of 16 months.
