Ideally,
going forward, the circulation element of the general plan will include a discussion of the transportation system
designed using metrics that capture connectivity (the fundamental purpose of transportation) rather than mobility (just one
facet of connectivity). Examples of such measures include number of jobs accessible within 30 minutes, number of retail
destinations reachable in a ten-minute walk, and number of hospitals accessible by a 45-minute transit ride. Even where metrics
like Level of Service are still used, local governments should consider the following ways to account for limitations:
• Use Level of Service during the planning process to size roadways, but not as a measure of individual project impacts.
• Level of Service should be balanced with other metrics when used, rather than triggering decisions by itself. Other metrics
are needed to measure the efficacy, comfort and safety of other transportation modes, and to measure
the proximity benefits
conferred by infill development. It is important to estimate the cost of achieving any Level of Service threshold, in order to
determine whether that threshold is fiscally feasible, and to identify, where possible, funding for long-term maintenance costs
associated with building to any Level of Service thresholds.
• Set Level of Service thresholds in consideration of the tradeoffs between mobility and other goals. Accommodating automobile
traffic has direct tradeoffs with greenhouse gas emissions, other emissions that affect air quality, pedestrian collision risk, and
active mode share and the resulting public health benefits. It also leads to sparser
land development patterns, creating indirect
tradeoffs with consumption of agricultural land and sensitive habitat, energy use, water use, and water runoff affecting water
quality and flood risk. A general plan should consider these tradeoffs when recommending a Level of Service objective.
Planning for safe transportation systems has often used LOS to attempt to streamline automobile flow, accommodating driver
error in an effort to reduce crash rates. This method of planning for safety may not most effectively increase safety or protect all
users of the system. Rather, proactive roadway design, reduced speeds, and reduction of overall VMT may be more effective. For
more information on analyzing
transportation safety impacts, see

Transit
Requirement Description:
As more of the population chooses alternatives to driving, roadway capacity becomes filled, and California strives to reduce VMT
and GHG emissions, transit availability becomes increasingly important. There are many important considerations for transit
in general plans. Policies, such as increasing density around transit corridors and increased transit infrastructure, can promote
and prioritize high quality transit, aligned with housing and economic development policies, which
in turn increases efficiency
of the overall transportation system. Promotion of equitable access to transit, through the analysis of available data to make
decisions, can help ensure all community members have access to core destinations, such as employment centers, schools, and
retail, and contribute to fulfillment of
environmental justice
requirements. Transit providers should be involved in general plan
processes, ensuring their alignment with community priorities.
Well-planned transit infrastructure can improve access to opportunity by making job centers, housing, schools, and other
major destinations accessible to a high numbers of residents. Providing infrastructure at transit stops for convenience and
safety,
such as proper lighting, covered shelter, and safe crossings; implementing transit priority on streets and bridges, such

as priority lanes, signals, and other
types of infrastructure; and utilizing
technology to communicate transit
patterns in real time can help speed
transit vehicles,
shorten travel
times, promote safety, and attract
additional passengers.
Coordinating transit stops,
stations, and routes with bicycle
and pedestrian infrastructure can
help create first and last mile
connections, promoting reduced
VMT for short trips and potentially
increasing transit ridership for a
greater range of residents.
Developers and employers can also
incentivize
transit ridership, and
general plan policies can promote
such programs through general
visions and goals or through specific
transit zones in the plan.

Active Transportation: Bicycle and Pedestrian Networks
Requirement Description:
The
Active Transportation Program
, enacted via Senate Bill 99 in 2013, funds pedestrian, bicycle, and
Safe Routes to School
programs (SRTS)
. This program ensures that at least 25% of investments benefit disadvantaged communities. Increasing
safe, connected bicycle and pedestrian networks in a city or county improves health,
economic mobility, GHG emissions,
and increases accessibility for numerous populations. Ensuring that infrastructure is safe for residents from ages 8 to 80, if
possible, captures the needs of recreational riders, ADA users, bicycle and pedestrian commuters, and all people in between. The
Complete Streets Act (2008)
requires cities and counties to plan for the development of multimodal transportation networks in
