G4-INTRODUCTION TO TRAVEL DEMAND FORECASTING Flashcards
is a process that involves prediction of most probable pattern of land development for the horizon-year, usually taken as twenty years, and the transport demands created by that land use.
TRANSPORTATION PLANNING
aims to establish the spatial distribution of travel explicitly by means of an appropriate system of zones.
TRAVEL DEMAND MODELLING
refers to the demand for trips that exists in any
area.
TRAVEL DEMAND
involves data concerning the travel maker
like age, sex, income, and vehicle ownership.
THE URBAN TRAVEL DEMAND FORECAST
involves city population, average city income, travel time or travel cost between city pairs.
INTERCITY TRAVEL DEMAND FORECAST
FACTORS AFFECTING TRAVEL DEMAND
-Location and intensity of land-use
-Socioeconomic characteristics of people living in the area
-The extent, cost, and quality of available transportation services
is the process of determining the number of trips that will begin or end in each traffic analysis zone within a study area
TRIP GENERATION
trips that originated or
destined at home
HOME-BASED TRIPS
trips that did not originate at home
NON HOME-BASED TRIPS
Travel behavior is a complex process where often decisions of one household member are dependent on others in the household.
INDEPENDENT DECISIONS
All shopping trips are treated the same weather
shopping for groceries or lumber.
LIMITED TRIP PURPOSES
Travelers may often combine a variety of purposes into a sequence of trips as the run errands and link together activities.
COMBINATIONS OF TRIPS ARE IGNORED
Trip generation models sometimes calculate trips as a function of factors that in turn could depend on how many trips there are.
Feedback, cause and effect problems
developed by the Federal Highway Administration (FHWA) to determine the number of trips that begin or end at the home.
CROSS-CLASSIFICATION MODEL
a statistical technique used to develop trip generation rates for both “work” and “other” trip
ends.
REGRESSION ANALYSIS MODEL
