GTS team members have worked on projects of all sizes in the United States and internationally. We advise public, private, and institutional clients. Our projects have ranged in scope from driveway access studies to master-planned communities and everything in between. Our work ranges from concept-level planning and strategies to detailed design with construction support.

GTS is leading the Southern California Regional Integration of Intelligent Transportation Systems (RIITS) Strategic Plan Update and Roadmap. The GTS team evaluated existing conditions and emerging trends, then conducted an analysis of regional concerns, system gaps, and the program’s strategic direction through a comprehensive stakeholder engagement process. The strategies will be organized into an implementation plan that covers the next five to ten years.

GTS prepared the lighting and electric vehicle (EV) charging plans, specifications, and estimates for this project. To this end, we undertook site investigations, background data gathering, photometric analysis, and coordination with adjacent developments, landscape architects, and City leadership. GTS also designed the power and communications infrastructure for the security system.

GTS worked with the City of Commerce on analyzing the Mixmaster Intersection, which is a critical component of the City’s transportation network. We explored alternative concepts that would improve overall safety and operational aspects without expanding or widening roadways. The project is (big) data-guided and examines the mix of traffic, signal timing, roadway striping, minor physical improvements, and improved signage, along with other innovative ideas pertaining to operations and management.

As part of this complete streets project, GTS provided communications and EV charging station design services. The project included installing conduits, 432 strands of fiber, inner duct products for future expansion, pull boxes, splice vaults, and distribution cabinets. The project tied into the data center at City Hall and the existing network to create a resilient fiber loop, connecting to all traffic cabinets, bus shelters, light poles, and smart poles that will be used for Wi-Fi access and other Smart City applications.
