Acceleration functions (a) of the IDM, (b) resulting from the CAH heuristic and (c) of the proposed ACC model as a function of the gap s and the velocity difference (approaching rate) Δv
from the leading vehicle.

(a) Resulting acceleration aACC of the ACC model, equation (2.4), as a function of the IDM acceleration for different values of the acceleration aCAH resulting from the CAH. Black line,
aCAH=2 m s−2; dashed line, aCAH=0 m s−2; dotted line, aCAH=−2 m s−2; da...

Response of (a) an IDM (solid line; dashed line, lane-changing vehicle) and (b) an ACC vehicle (solid line; dashed line, lane-changing vehicle) (‘car’ parameters as shown in table 1) to the lane-
changing manoeuvre of another vehicle immediately in front of ...

Response of (a) an IDM (solid line; dashed line, lane-changing vehicle) and (b) an ACC (solid line; dashed line, lane-changing vehicle) vehicle to an abrupt lane-changing manoeuvre of another
vehicle immediately in front of the vehicle under consideration.

Response of a platoon of ACC vehicles to an abrupt lane-changing manoeuvre of another vehicle (v=80 km h−1) in front of the platoon with an initial gap of only 10 m.
