Abbreviations
MPO
Metropolitan planning organization
What is an MPO?
a regional government entity that is responsible for urban transportation planning,
decision-making, and allocating federal transportation funds.
All or nothing
Traffic assignment
What is trip distribution?
the second step in the four-step travel demand model, following trip generation, and it determines where trips generated in one zone are likely to be attracted to other zones, creating an origin-destination (O-D) matrix
Accessibility is the measure of how ______ it is to travel from place to place.
easy
TAZ
transportation analysis zone
What is a TAZ?
a spatial or geographic unit of analysis used in travel demand modeling.
Destination choice
Trip distribution
What is trip generation?
the first step in transportation forecasting, predicts the number of trips originating in or destined for a particular traffic analysis zone (TAZ). It estimates the number of "trip ends" produced and attracted to each TAZ, considering factors like land use, demographics, and accessibility.
The _____ ______ ______ _______ is the MPO for the SLC metro area.
Wasatch Front Regional Council
LRTP
long range transportation plan
What is a LRTP?
a plan that an MPO must develop that outlines the vision and goals as well as
the anticipated projects in the region over the next 20 to 25 years.
Gravity
Trip distribution
What is mode choice?
mode choice is the third step, where the model predicts the proportion of trips between each origin and destination that will use a particular transportation mode (e.g., car, bus, train).
The NHTS dataset consists of 5 files: the long distance travel file, ____ file, _____ file, ______ file, and vehicle file.
person, trip, and household
TIP
transportation improvement program
What is a TIP?
a plan that an MPO must develop that outlines specific fiscally-constrained
projects that a region will undertake in the next 4 to 5 years.
Multinomial logit
Mode choice
What is traffic assignment?
traffic assignment is the final step that determines how trips, generated, distributed, and assigned to a mode, are routed through the transportation network, considering factors like travel time and congestion
Activity- based models are ____-based models, instead of the traditional ____-based 4-step model.
tour, trip
IIA
independence from irrelevant alternatives
What is IIA?
a property of multinomial logit models that means that the ratio of choice
probabilities does not change with the addition/subtraction of other alternatives.
User equilibrium
Traffic assignment
What is the NHTS and what is it used for?
National Household Travel Survey (NHTS)
A ___-____- ___ trip does not begin or end at home.
non-home-based
