Managing Demand for Parking
• Support alternative transportation. Travelers by non-auto
modes do not require automobile parking. Quality bicycle,
pedestrian, and transit access facilities and services (See
e.g.
City of Berkeley
), and development proximate to those
facilities, reduce motor vehicle mode share and therefore
parking demand. Adequate, convenient, and secure bicycle
parking, including around transit stations, facilitates cycling
and increases cycling mode share.
• Convert parking to
parklets
, which increase public space and
can improve neighborhood vibrancy.
• When providing on-street parking, design it in a manner
that calms traffic and enhances bicycle and pedestrian safety
and comfort. This may include
reverse angle parking
and
parking-protected bicycle lanes
.
• Attach a cost to parking. Construction and maintenance
of parking is costly. Jurisdictions may wish to consider
the benefits of optimizing parking prices to reflect the
equilibrium between supply and demand, to help improve
traffic flow, or to reduce VMT and GHGs. (See e.g.
City of
San Diego
;
City of Sacramento
) Further, fees collected can
be reinvested in a number of ways, including neighborhood
benefits districts, that can increase neighborhood vibrancy.
Managing Supply of Parking
• Remove minimum parking requirements. Parking restrictions, such as residential parking permit programs, can be
implemented to prevent spillover parking. Parking provision can be left to the market, pricing can be deployed, or parking
maxima can be provided.
• Set parking maxima. Especially in TOD or mixed-use development areas, establishing maximum parking requirements instead
of minimum requirements will mean that space is available for other uses (See e.g.
Sacramento County
;
City of San Jose
).
• Manage the use of existing spaces rather than provide additional parking. Prioritize spaces based on location (e.g. proximity
to employment centers) and intended use (e.g. short- or long-term). Implement shared parking or establish parking benefit
districts. (See e.g.
Sacramento County
) Optimizing use of existing parking will help make efficient use of land within the
jurisdiction’s boundaries.

Traffic Control Around Schools
High volumes of pedestrian traffic, vulnerable users, and
other factors create increased need for safety around schools.
Considerations in roadway design should take in to account
the specific needs of the population, including bicycle and
pedestrian access, transit and drop off needs, and safety
around crosswalks, intersections, and roundabouts.
The Safe
Routes to Schools National Partnership
, with support from
CalTrans’ Safe Routes to School program
, provides
guidance
and resources for improving traffic control around schools,
including signage, pavement markings, signals, and other
infrastructure. For additional guidance on traffic control
specifically around schools, see the
CalTrans Manual on
Uniform Traffic Control Devices
, including
Section 3c
on
roundabout markings and
Part 7
for traffic control around
schools.
Addressing Tradeoffs and Maximizing Co-benefits in
Circulation
The transportation network should be designed to
accommodate multiple competing interests, as well as to
maximize co-benefits. Potential areas for co-benefits, such as
safer streets through slower traffic, greater economic activity
through improved walkability, and increased positive health
outcomes through improved active transportation, should be
considered in making decisions around transportation.
The circulation element should address the tradeoffs between
various interests rather than listing desirable but mutually
exclusive outcomes. The following are some of tradeoffs that a
circulation element might address. Some of these tradeoffs will
involve agencies distinct from the city or county, such as some
transit systems, highlighting the importance of coordination
between stakeholders involved in circulation planning and
implementation.

• Roadway design speed and risk to pedestrians and cyclists
• Breadth of coverage of transit system v. cost
• Provision of bicycle facilities v. provision of additional motor vehicle capacity
• Transit priority measures (e.g. signal priority and queue jump lanes) v. automobile capacity
• Accommodation of potential emergency vehicle turning movements v. design for pedestrian safety
• Accommodation of freight vehicles v. pedestrian safety
• Automobile throughput and speed v. traffic calming measures such as narrower travel lanes, roundabouts, raised medians,
speed tables, small curb radii, etc.)
Goods Movement
Freight movement is essential for any community to thrive, by allowing the exchange of needed goods and stimulating local
and regional economies. Depending upon geography and community characteristics, local governments should plan for goods
movement in multiple modes, including air, rail, ship, and truck. A general plan should address transportation improvements
that facilitate the timely movement of goods, meet the needs of local business and industry, and support the efficient transfer of
goods between truck, rail, and other transportation modes. These interests of goods movement must be balanced with the trade-
offs that may include negative impacts to safety, air quality, and noise described in the previous paragraph. Increasing general
purpose roadway capacity on a congested roadway may not facilitate freight vehicle travel, due to
induced travel effects
(mostly
passenger vehicles); freight-only facilities may better accomplish this objective.
While freight moves throughout the state in multiple ways, trucks specifically:
• Emit diesel particulate matter (DPM), which is a localized pollutant that is particularly hazardous to human health
• Generate high noise levels
• Pose special collision hazards because of their size, especially to vulnerable road users, and especially during turning
movements, where rear wheels can follow a shortcut-track and collide with pedestrians and cyclists
For these reasons, truck routes should be designed to minimize risk to areas containing concentrations of sensitive receptors and
vulnerable road users. Also, goods movement facilities (distribution centers, rail yards, and ports) should be placed in locations
that do not bring high levels of truck traffic near residential areas or schools whenever possible. Engaging school boards, goods
distributors, and community members to coordinate the
land use element
with the circulation element, freight mobility plans,
and other relevant efforts may help assess tradeoffs and needs in
locating facilities
.
Land use
and circulation elements may also be coordinated for freight movement in congested or high traffic corridors, such as
by designating specific freight zones, lanes, or management practices, to improve efficiency overall. Policies specific to the needs
of a community, depending on factors such as density, proximity to goods movement facilities, and average daily traffic (vehicle
and non-vehicle) may help ease safety and congestion issues associated with urban freight movement.
