Life-style and travel demand

The use of the life-style concept in travel demand models

The concept of life-style is becoming a major differentiating trait between population groups substituting for economic and social classes. This paper describes the utilization of the concept of life-style in the context of travel demand models. life-style is defined as a pattern of behavior under constrained resources which conforms to the orientations an individual has toward three major 'lif...

Passenger Travel Demand Forecasting

Demand Elasticities for Highway Travel

An elasticity summarizes a large amount of information in a single number. Levels and distribution of incomes, price levels of the specific good and of substitute and complementary goods, preferences and tastes, transaction costs, etc., can, ceteris paribus, affect the measured value of any particular demand-price elasticity. The elasticity concept normalizes for the measurement scales (e.g., p...
