SYSTRA’s expert knowledge of multi-modal service planning allow for the seamless development of service plans/schedules, travel times, operating statistics and vehicle requirements. SYSTRA has assisted agencies in preparing Fleet Management Plans which highlight existing and future fleet requirements, system expansions, maintenance and overhaul programs, and procurement strategies.Representative Projects:
SCAG High Speed Ground Transportation System Alternatives Analysis Study
Los Angeles, CA
The Southern California Association of Governments (SCAG) requested SYSTRA to analyze two high-speed ground transportation modes – high speed rail (HSR) and magnetic levitation (MagLev) – as part of SCAG's goal of recommending a preferred mode for high-speed intercity and long distance commutation travel for the Los Angeles metropolitan area.
Preferred alignments identified in previous studies for each mode were validated and adjusted as needed for mode-specific design criteria. HSR and MagLev modes were tested on both alignments, which link Los Angeles International Airport, Los Angeles Union Station, and Ontario Airport, with options for additional stations along the routes. The tested alignments, which use existing freeway and freight railroad right-of-way, have been identified by SCAG as initial operating segments that are part of a long range high-speed ground transportation system.
SYSTRA provided track design and operations analysis to develop an operations plan. Civil speed restrictions due to curves were calculated using the design criteria of each mode, and accounting differing ability for tilting through curves. Operating parameters, including acceleration and deceleration characteristics, maximum system speeds, signaling systems and automated operations, and station dwell times were prepared and vetted through the California High Speed Rail Authority and TransRapid International, a principal developer of MagLev systems. Overall travel times were then developed for use in ridership modeling. Ridership estimates and alternative service plans were iteratively developed to determine the most cost-effective service plans.
Operations and maintenance and capital costs for each transportation system were also included, focusing on how modal design criteria (such as maximum grade and automated vehicle operations) impact costs, as well as concerns related to co-habituating rights-of-way used for public roadways and freight rail operations.
