Socioeconomic Characteristics, Travel Patterns and Long Range Plan for Los Angeles, California, USA

LA County's population, employment and vehicles are projected to grow 28% to 37% by 2025. Due to urban sprawl and complex multidirectional travel pattern, the vehicle miles traveled are projected to increase by 53%. The 4000-mile freeway system in LA County's urbanized area cannot be expanded easily; therefore, more emphasis is given to alternative transportation solutions such as HOV-carpool lanes and improving transit services. Four primary alternatives (e.g., Vehicle Moving, People Moving, Financially Constrained, and Financially Unconstrained Alternatives) were tested. In addition, sensitivity tests beyond conventional solutions were applied to Constrained and Unconstrained Alternatives.
