Question 1

parameters of traffic flow theory

Answer 1

density, speed, flow

Question 2

traffic flow models and differences between models

Answer 2

macroscopic (large planning networks, no detail, average values of q,v,k)
microscopic (individual vehicle behaviour, high detail)
mesoscopic (individual vehicle behaviour within large network)

Question 3

problems with high fidelity models (what are they)

Answer 3

accurate but take ages to compute and set up and have more room for error in calcs.
require calibration

Question 4

problems with low fidelity models

Answer 4

cheap and easy but less accurate and less valid.
