Transit Operations

Linscott, Law & Greenspan Engineers prepared a Pedestrian Study for the Palomar Transit Station Project in the City of San Marco. The study includes a safety and operations evaluation of the existing and proposed pedestrian crossings at the Palomar College Sprinter station. LLG developed a site-specific pedestrian model and calculated pedestrian flow rates to determine Levels of Service (LOS). The pedestrian LOS was used to determine the design width of the proposed pedestrian bridge across Mission Road and the North County Transit District (NCTD) Sprinter station platforms. ADA compliance was also tested for proposed elevators that would serve the pedestrian bridge.

LLG prepared a comprehensive traffic study for the University Towne Centre (UTC) Revitalization project located in University City community of the City of San Diego. The redevelopment project included the development of 750,000 square feet of commercial retail and 250 multi-family units in addition to the development currently on site. The project was processed as a Master Planned Development Plan, and as a result, seven alternative projects were considered. The UTC Revitalization project also involved the introduction of a new transit center. Two possible transit center alternatives were identified, developed in detail, and evaluated in depth. The location and design were developed through discussions with SANDAG, MTS, and the City of San Diego.

LLG was retained by the City of Chula Vista to prepare a Mobility Study for the Palomar Gateway District (PGD) Specific Plan. The PGD is one of five planning districts contained within the Southwest Area Plan in the City of Chula Vista’s General Plan, and is designated as a Transit Oriented Development (TOD). The Mobility Study reviewed the current and future transportation system in the context of the General Plan land use designations and provided recommendations to promote mobility within the district for all travel modes and abilities. An opportunity/ constraints matrix was prepared assessing pedestrians, bicycles, transit, light rail and vehicular traffic. Opportunities were termed high priority, medium priority and/or low priority, to assist the City with prioritizing potential improvements.

The Aviation Station project is a transit-oriented development (TOD) proposed immediately adjacent to the existing Metro Green Line Aviation Station at Aviation Boulevard and Imperial Highway. The Aviation Station provides a unique mix of a light rail station, associated transit bus hub facilities (including shuttle service to LAX), a park-and-ride lot, and a Caltrans maintenance facility. In addition to preparing the EIR traffic impact study for the TOD project, LLG worked with the project design team, as well as representatives from Metro, Caltrans, various transit agencies (e.g., Metro, Santa Monica Big Blue Bus, Los Angeles World Airports, etc.), in the modification and enhancement to Aviation Station to promote connectivity between the proposed TOD and the light rail station, provide improved transit bus drop-off/pick-up facilities (including layover areas), convenient access for park-and-ride users, and safe and efficient access for Caltrans-related maintenance vehicles. LLG’s review included documentation of the existing travel patterns related to the various population groups (transit buses, park-and-ride users, Caltrans vehicles, etc.) and recommendations for enhancements to site access and internal circulation to promote the use of light rail and public bus transportation. Recommendations have been provided by LLG to allow for safe pedestrian movements between the light rail platforms and the TOD, the transit bus drop-off/pick-up area and the park-and-ride lot. LLG prepared vehicle maneuvering studies to allow the design team to allocate sufficient area to provide safe and efficient movement of various size transit bus and Caltrans vehicles.
