CORSIM
Microscopic
Traffic Simulation Model
CORSIM includes both NETSIM (for surface street
simulation) and FRESIM (for freeway simulation). Version 6 of
CORSIM offers the following new
features:
- Simulation
Logic: Version 6 now offers
improved simulation
logic for lane changing, spillback checking, diagonal movements, complex intersection
modeling,
freeway acceleration lanes, deceleration lanes, ramp meters,
car-following, origin-destination modeling, and
setting goal lanes.
An
enhanced random number generator will produce better
distributions, for
improved stochastic modeling.
- Actuated Control: Actuated controller parameters may now vary
from time period to time period to simulate different time-of-day plans.
The number of actuated controllers is now dynamic and
limited only by the number of nodes in the network.
- Emergency Vehicles: Emergency vehicles (EV) can now be simulated, and can cause
signal pre-emption if desired. EV sample data files and EV
documentation are now included in the installation.
- Modeling Options: 1) CORSIM can now simulate up to eleven
through lanes in one direction on a mainline freeway link, i.e., 5
through lanes plus 6 full auxiliary lanes. 2) The
minimum desired free-flow speed on surface streets has been reduced to
one mile per hour, to approximate vehicles dwelling in locations such
as airport passenger pickup zones. 3) Truck lane
logic was modified to provide exclusive truck lanes in which non-truck
vehicles are prohibited. 4) Sign control can now be
active in one time period and removed in the next time period, or vice
versa. 5) NETSIM can now simulate up to 9 lanes per intersection
approach, up to 3 lanes per turn pocket, and turn
pockets as long as 9999 feet.
6) CORSIM and TRAFVU can now
handle left-hand drive networks, with TSIS
Next as the preferred input editor.
