- •
Methods are proposed to study the impact of FFS under different control strategies.
- •
Several measures of the performance of freeway system are defined.
- •
With the increasing FFS, TTN will increase first and then change to decrease.
- •
With the increasing FFS, AD will decrease first and then change to increase.
- •
There exists an optimal FFS corresponding to the best performance of system.
