4. Demand modeling Assumptions
1- Demand is derived (Each trip has a purpose)

3-Demand is a function of activities and land uses (independent of supply and opportunities)
4- Temporal stability of relationship between zone characteristics and trip rates
5- Trip is related to its respective activity
