Transportation Planning

CE 573

Lecture 2

Issues for Today

• Transportation planning and decision making

• Multimodal transportation planning

• Travel behavior and population characteristics

• Sustainable transportation

• Assignment for next class

Transportation system

– Mobility of people and goods– Influences patterns of growth and economic

activity

Changes to system to achieve following objectives

– Improved air quality– Enhanced viability of economic centers– Increased mobility – Promote sustainable community

development

Product of planning is…

– Understanding problems

– Identifying alternatives

– Selecting best alternative

– Developing implementation strategies

Planning inputs decision making process

– Outline of investments necessary to correct system deficiencies

– Operations improvements to existing network

– Technological improvements to existing network

Communication should be such that:

– Limited technical/analytical aptitude of decision makers

– Desired information is available– Needed information is available

Decision makers

– Elected officials– Transportation agency managers– Private sector shipping managers– Corporate officials concerned with employee

transportation

A transportation plan

– View of future system characteristics– Provides context for subarea project studies– Anticipate future development– Influence where future development occurs

Decision-oriented transportation planning

– First: understand how the decisions will be made

– Second: determine the information requirements for those decisions

– Third: identify data and analyses needed to produce required information

Multimodal transportation system

Moscow, Idaho Case

– Pedestrian network– Bike network– Roads network– Bus network– Rail network– Intermodal connector

Multimodal transportation planning

Becoming a Less Auto Dependent City

– Supply management:

– Demand management: actions taken to influence demand intensity, timing, spatial distribution

– Land use management: trip making patterns, volumes, and model distributions are function of spatial distribution of land use

Travel Behavior and Travel Pattern Factors

– population characteristics– economy– societal concerns– transportation legislation– technology of planning

Population Characteristics Influencing Travel Behavior

– Trips per capita– Population distribution– Employment– Telecommuting**– Occupation**– Bus fees**

Demographic variables and travel behavior

– Income– Age– Automobile ownership– Household

Population characteristics vs travel behavior

– explain current behavior– predict future behavior

Sustainable transportation

• Cleaner fuel• Change transportation pricing to reflect true

societal costs
