OUR
PROJECTS
GTS provides a range of advisory and technology-powered services to deliver next-generation transportation solutions for municipal, institutional and private clients.

GTS provided traffic engineering signal upgrade services for the signalized intersection of Figueroa St. and Victoria St. / 190th St. in the City of Carson. GTS carried out various safety, operational, and accessibility upgrades as part of this design.
This Highway Safety Improvement Program (HSIP) grant-funded project will provide protected left-turn-signal phases at all legs of the subject intersection, safety improvements for road users and pedestrians, and ADA-compliant curb ramp design. The design services included coordination with the City of Los Angeles (which has shared jurisdiction at the intersection) as well as with Caltrans for funding administration purposes (right of way certification, RFA for construction, E-76, etc.).

GTS prepared professional engineering design services for construction plans, specifications and estimates as required for removal of existing street lights and replacement with new concrete poles, mast arms and luminaires. The project included voltage drop electrical calculations, conduit fill, proper lighting circuits, conduit routing, breakers, lighting controls and groundings, electrical notes and diagrams on the design plans, and SCE coordination for proposed power services/meter pedestal, in conformance with City of Upland’s requirements.
Traffic Signal Design of Figueroa St. and Victoria St./190th St., Carson, CA

GTS supported the City of Burbank with the Phase X resurfacing program (for Zones 9, 10, 11, & 12), which includes over 22 roadway miles. GTS utilized aerial imagery and performed field review prior to the base and design preparation. The striping restoration utilized (when available) as-built and roadway rehabilitation plans and included field reviews for lane widths, locations of speed bumps, fire hydrants, etc. The City typically leverages the roadway resurfacing program to add bike lanes as well as crosswalks at various locations. GTS also prepared the loop restoration for 18 signalized intersections that were impacted by the road rehabilitation.
Burbank Resurfacing Program - Signing and Striping Restoration and Loop Replacement Plans

GTS provided traffic engineering signal upgrade services for 40 of the 224 signalized intersections in the City of San Bernardino, where various safety, operational, and accessibility upgrades are required. This Highway Safety Improvement Program (HSIP) grant-funded project will replace or install new equipment to the existing traffic signal system, including traffic signal head improvements, pedestrian signal head improvements, and pedestrian pushbutton improvements, among others.
City of San Bernardino, Traffic Signal Upgrade PS&E Services

GTS provided traffic engineering design services for both Phase I and Phase II of the City of Carson bicycle design project. GTS services include supporting the conceptual design elements of the project as well as the design development to produce the final plans, specifications, and estimates. GTS carried out the design of signing and striping as well as traffic signal designs and or modifications.
The design is per the requirements of the California Manual of Uniform Traffic Design as well as the Highway Design Manual. The design is geared to address safety, operational, and accessibility considerations, with a special focus on vulnerable modes of transportation.
Alpine St., Vernon Dr., and Palm Ave. Street Lighting, Upland, CA

As part of this complete streets project, GTS provided communications design services. The project included installing conduits, 432 strands of fiber, innerduct products for future expansion, pull boxes, splice vaults, and distribution cabinets. The major project goals included: bringing fiber to the Design District along all major commercial corridors; tying the new fiber to the datacenter at City Hall and the existing fiber along Santa Monica Blvd. and San Vicente Blvd. to create a resilient fiber loop; bringing fiber into all traffic cabinets in the Design District; bringing fiber into all City bus shelters and bus stops; and bringing fiber to all light poles and/or smart poles that will be used for Wi-Fi access points and other Smart City applications.
Melrose Complete Street Communications and EV Charging Stations Design, City of West Hollywood

GTS provides transportation planning and traffic engineering on-call services to the City of Hermosa Beach. We assisted the City in its COVID-19 relief efforts to support small businesses by providing parklet designs for outdoor dining. GTS produced plans, specifications. and estimates (PS&E) for road dieting and installing Class II bicycle facilities in the downtown area (Hermosa Ave. and Pier Ave.) to provide space for walking, biking, and outdoor dining, while ensuring social distancing.We have provided the design for more than 20 parklets and carried out the traffic engineering feasibility study of closing a right turn slip lane.
City of Hermosa Beach Transportation Planning and Traffic Engineering On-Call

GTS carried out the traffic engineering tasks for this City of Santa Monica project that is closing a key bike and pedestrian network gap and serving as critical linkage between the Michigan Avenue Neighborhood Greenway (MANGo) and Bergamot Expo Station.
The Active Transportation Planning (ATP) grant-funded project posed the challenge of designing as closely as possible to Caltrans Highway Design Manual standards with limited space available for improvements. GTS worked closely and tirelessly with Caltrans and the City on developing and testing various alternatives that are acceptable to both agencies. GTS performed the traffic analysis, truck turning analysis, traffic signal design, signing and striping design, and traffic control plans. GTS also designed the street lighting and emergency blue light phone services over a 4G network.
City of Carson Dominguez Channel Bicycle Design

GTS prepared the lighting and electric vehicle (EV) charging plans, specifications, and estimates for the Emergency Shelter Parking Lot in the City of Pomona.
The project included site investigations, background data gathering, coordination with adjacent development, photometric analysis, and coordination with the City, as well as coordination with the landscape architect on the electric service for irrigation.
GTS also designed the power and communications infrastructure for the security system. Designs included plans, specifications, quantities, and cost estimates.
