What is the role of the transportation planner?
Reference: Institute of Transportation Engineers

What is the Role of a Transportation Planner?
• Transportation planners work to improve the quality of life of the communities they serve
• by developing sustainable solutions to issues such as urban sprawl, traffic congestion, air pollution, access to jobs, social events, etc, and the mobility needs of an aging population
Old Paradigm - Long Range Transportation Models
Local Future Land Use Plans
Employment & Household Projections Projected
Deficiencies (congestion) and Alternatives Analysis
Recommended Changes – typically to add capacity
•Assumes future land use is valid
•Assumes community will develop per its plan

Often not specified Specific with costs and funding
Practicality Bold ideas / “just a plan” Engineering feasibilityMajor Difference:•Transportation based on planned Land Use•Land Use has limited consideration of transportation
A New Paradigm
• Link land use with transportation:• Land use arrangement to reduce peak hour auto trips• Site design to support bicycling/walking/transit• Combine land-use planning with transportation planning
(regional, community, and site specific)
• Increased cooperation among all parties involved in land use and transportation
• Operate in limited funding environment by planning practical (and affordable) and sustainable solutions to meet our transportation system needs
Role of the Transportation Planner
• “Bridge the gap”• Educate parties in an understandable way• Focus on long term• Advocate for underserved groups• Environmental justice• Use transportation to improve community
sustainability

Public Involvement• Facilitate, educate to
gather meaningful input• Brochures• Open house• Public workshops• Advisory committees• “Road show” • Visualization/simulation

A transportation planner does . . .
• Long range plans• Corridor simulation
models• Flexible design/street
widths/road diets (traffic calming/CSS)
• Non-motorized plans & walkable design
• Demand management
• Transit oriented land use and design
• Access management• Overlay zones• Form-based codes• Transportation to
support economic development
Corridor Planning• Identify the
function and character of major streets
• Traffic operations (Level of Service)
• Accommodate all users
• Access system • Road and
streetscape design (Context Sensitive Solutions)

Access ManagementCost effective traffic management methods
to:• Promote the flow of traffic• Improve safety of pedestrians & vehicles• Improve aesthetics of roadway areas…by managing the location, quantity, type
& design of access to a roadwayStructures

Benefit: Safety
• Access management can help reduce injuries and property damage due to crashes
• Doubling of access density from 10-20 access points per mile often results in about a 40% increase in expected crash rates*

Promote Effective Solutions
• Transportation planners can promote effective solutions such as roundabouts, ITS, creative interchange design, multi-modal streets and traffic calming measures.
• This includes both technical analysis and building support from other professionals, the public, and decision makers.

Road Diets• Reducing # of traffic
lanes to provide left turn, transit, or bike lane
• Consider:• Function & environment• Traffic volumes (consider for
8,500 – 24,000 vpd)• Peak hour volumes & Level
of Service• Crash types, pedestrian,
bike, & transit activity• Impact on parallel roads

Transit Oriented Development (TOD)
• Moderate to higher density• Within an easy walk• A mix of uses• Designed for the pedestrian• New construction or
redevelopment• Increases transit ridership• Strong benefits
Using Transportation as a Catalyst
• Rather than respond to land use, transportation investment can be a catalyst to sound, sustainable growth and development
• Increase property value by improving access and safety
• Balance land use with traveler needs• Examples:
• Convert one-way to two-way• Add on-street parking• Add transit (Bus rapid transit/ streetcar/light rail)

Manage Demand• Manage transportation demand to
influence the intensity, timing and spatial distribution
• Purpose: reduce the impact of traffic or enhance mobility options• Offering commuters one or more
alternative transportation modes and/or services
• Providing incentives to travel on these modes or at non-congested hours, or
• Providing opportunities to better link or "chain" trips together, and/or incorporating growth management or traffic impact policies into local development decisions.
