Transportation Analysis Policy Development

Project Description

The City of San Mateo is developing a new transportation policy to meet State requirements set by Senate Bill (SB) 743. The bill shifts how a project’s transportation impacts are analyzed; from automobile delay typically measured by Level of Service or LOS, to Vehicle Miles Traveled (VMT), which measures the total amount and distance traveled by single-occupancy vehicle to a destination. VMT provides for a more broad multimodal transportation analysis from a regional perspective, whereas LOS typically focuses on automobile impacts within a more localized area.

This change from LOS to VMT analysis is expected to align transportation impact analysis and mitigation with statewide goals to reduce greenhouse gas (GHG) emissions and increase use of active transportation.

Project Update

The City is working on developing a new transportation policy to transition from using Level of Service (LOS) to Vehicle Miles Traveled (VMT) as the methodology to assess transportation impacts of development and infrastructure projects under the California Environmental Quality Act (CEQA). Only analyses under CEQA require the use of VMT as the metric for transportation analysis.
