Indicate True (T) or False (F):
a. The 4-step network level transportation planning approach is suitable to estimate travel demand along a corridor.
b. Traffic assignment does not refer to the estimation of zonal trip productions and attractions.
c. A logit model is not used to estimate modal utilities.
d. Mobility does not represent the operational performance of a transportation system.
e. Maximization of consumer surplus does not represent the objective of maximization of benefit of public projects.
f. Ton-miles cannot be used as a measure of freight transportation demand.
g. A change in the level of service (or quality) of a transportation system cannot be represented by a shift in the supply curve.
h. Cross-sectional models can be used to model demand functions.
a. The 4-step network level transportation planning approach is suitable to estimate travel demand along a corridor.
( TRUE ) (T)
EXPLANATION: The expressions site specific, corridor, areawide, metropolitan are used to describe variations in the scope of problem.This is the main scope of analysis and levels of planning.
b. Traffic assignment does not refer to the estimation of zonal trip productions and attractions.
( TRUE ) (T)
EXPLANATION: The estimation of traffic assignments are the link flows, volume to capacity ratios, congested travel times and congested speeds.
Trip productions and attractions are mainly linked Home end of Home based trip.
c. A logit model is not used to estimate modal utilities.
( FALSE ) (F)
EXPLANATION: One of the possible approaches to estimate modal utilities is the logit model or logistic regression.
d. Mobility does not represent the operational performance of a transportation system.
( FALSE ) (F)
EXPLANATION: In developing cities across the world can help meet the growing mobility needs of residents . The different design options available and their impact on operational performance of transportation system.
e. Maximization of consumer surplus does not represent the objective of maximization of benefit of public projects.
( FALSE ) (F)
EXPLANATION: Both consumer surplus and producer surplus of all public projects are taken into consideration and impact the project savings.
f. Ton-miles cannot be used as a measure of freight transportation demand.
( FALSE ) (F)
EXPLANATION: Ton miles is the primary physical measure of freight transportation output. Reflects both the volume shipped (tons) and the distance shipped (miles).
g. A change in the level of service (or quality) of a transportation system cannot be represented by a shift in the supply curve.
( FALSE ) (F)
EXPLANATION: The change in level of service is the cause which include in the natural factor.
h. Cross-sectional models can be used to model demand functions.
( TRUE ) (T)
EXPLANATION: Model demand functions can be identified by many estimations and in tthis cross sectional model is one of it.
