Final answer:
Transport Network Analysis is a mathematical model used to study traffic flows and routes. The correct answer is c) Have few constraints on travel. In reality, there are several constraints on travel, such as road capacity, traffic regulations, and geographic limitations.
Step-by-step explanation:
Transport Network Analysis is a mathematical model used to study traffic flows and routes. The correct answer is c) Have few constraints on travel. In reality, there are several constraints on travel, such as road capacity, traffic regulations, and geographic limitations. The model also uses geometric dataset to represent the road network and determine the flow of traffic.
