ODAS ModelPeeta. Paz. DeLaurentis. “Stated preference analysis of a new very light jet based on-demand air

service.” 1 Jan 2008.

Dayjet CorpCeased operations in Sept. 2008

Goals

• Interaction of ODAS with rest of transportation network

• Could relieve congestion at commercial airports?

• Scenarios most favorable to ODAS? (pricing, demand, etc.)

• Government aid/funding for an ODAS company?

Method

• Agent-Based Model

• Collection of decision-making “agents”

• Set preferences based on parameters (socioeconomic, etc.)

• On a model transportation network

• Need behavior models for travelers

Analysis

• Survey responses analyzed in LIMDEP

• Discrete-choice (logistic) statistical models built

• Results used to build behavioral models for “agents”

• 12 Single-combination models

• 2 Trip-purpose switching models

Summarized Results

• Higher educated individuals more willing to switch

• Higher income individuals more willing to switch

• Older individuals less willing to switch

• More likely to switch if near job or neighborhood

• More likely to use at small airports than major airports

The Model

Demand DistributionDemand Saturation

Ongoing Study

• Model framework still under development

• Researching parameters for nodes on network

• Introduce high-speed rail in future models

• Hope to show ODAS can relieve congestion, delays, etc.

• May spur further interest in development and funding.
