Comparative Analysis of Travel Patterns from Cellular Network Data and an Urban Travel Demand Model

Statewide Rural-Urban Bus Travel Demand and Network Evaluation

This paper examines the characteristics of intercity bus riders within Tennessee and proposes methods to identify service gaps and prioritize network expansion, particularly focusing on rural-urban connections. Data were collected through an on-board survey and compared with intercity auto trips. Compared to personal auto users, intercity bus riders are more likely to be of minority races, unem...

The Measurement of Urban Travel Demand

It is a truism that the transportation system is a critical component of every urban economy, and that transportation policy decisions can have a profound effect on the development of the urban system. Public transportation projects are often massive and mutually exclusive, with irreversible cumulative effects over long periods. If major social losses are to be avoided, careful planning based o...

Network Effect of Air-Travel Demand (PRELIMINARY)

Flight frequency is an important determinant of air-travel demand, but must be sustained by adequate demand, implying a feedback effect. Frequencies of link-sharing routes are related, implying a peer effect. The paper examines the effects, using a model of airline network where flight frequency is endogenized with passenger flow. An estimation strategy is proposed to help correct the possible ...

Network Effects of Air-travel Demand

As demand increases, airline carriers often increase flight frequencies to meet the larger flow of passengers in their networks, which reduces passengers’ schedule delays and attracts more demand. Focusing on the “network effects”, this paper develops and estimates a structural model of the U.S. airline industry. Compared with previous studies, the model implies higher cost estimates, which see...
