Siqing earned a MS in Transportation Engineering. Previously, she had received a Master of Urban Planning degree from Texas A&M University and has interned with CHS since summer of 2017. Siqing’s academic research covered Bus Rapid Transit, rail transit, shared mobility, smart card data, active transportation planning, and freight planning.

Nate joins us after receiving his Master of City and Regional Planning from the University of North Carolina.

Congratulations to TJPA on Opening the Salesforce Transit Center


August 2018

CHS Consulting Group congratulates the Transbay Joint Powers Authority (TJPA) on completing San Francisco’s Salesforce Transit Center, the largest regional transit hub west of the Mississippi River. The Transit Center was conceived as the “Grand Central Station of the West,” where a multitude of local, regional, intercity bus and rail lines, and California High Speed Rail will converge.

The Salesforce Transit Center officially opened to the public with a neighborhood block party on August 11, 2018; the following day, 27 AC Transit Transbay bus lines, along with regional service from Amtrak, Greyhound, Westcat Lynx, and Muni Treasure Island Service, began serving the new third level bus deck. San Francisco Muni local buses have been operating from the street-level Bus Plaza since June.

CHS is proud to have worked with TJPA and the design team to help bring this ambitious project to fruition. CHS designed traffic signals at seven locations: five on surface streets adjacent to the Transit Center, and two on the elevated bus deck leading to and from the San Francisco-Oakland Bay Bridge. The signal designs feature Transit Signal Priority (TSP) for at-grade intersections, timing and coordination plans for the elevated bus deck, signal synchronization between the bus deck signals and the surface intersection adjacent to the terminal, and Changeable Message Signs (CMS) on the bus deck.

Planning and design are underway for a 1.3-mile extension that will bring Caltrain commuter rail to the Transit Center. CHS is proud to be an active participant on this project as well, responsible for transit and traffic engineering tasks.
