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
