1. A system for mitigating traffic congestion for a vehicle, the system comprising:
a plurality of vehicle sensors;
an automated driving system;
a controller in electrical communication with the plurality of vehicle sensors and the automated driving system, wherein the controller is programmed to:
determine a traffic signal phase of a traffic signal in an environment surrounding the vehicle using the plurality of vehicle sensors, wherein the traffic signal phase includes one of: a red phase and a green phase;
activate the automated driving system to drive the vehicle for a predetermined maximum time-period in response to determining that the traffic signal phase is the green phase, wherein to activate the automated driving system to drive the vehicle, the controller is further programmed to:
determine a system activation state, wherein the system activation state includes one of: a system active state and a system inactive state, wherein to determine the system activation state, the controller is further programmed to:
determine a drive mode of the vehicle, wherein the drive mode includes one of: a forward drive mode and a non-forward drive mode;
determine a brake hold state of the vehicle, wherein the brake hold state includes one of: a brake hold active state and a brake hold inactive state;
determine an accelerator pedal position of the vehicle; and
determine the system activation state to be the system active state in response to determining that the drive mode is the forward drive mode, the brake hold state is the brake hold active state, and the accelerator pedal position is less than or equal to a predetermined accelerator pedal position threshold;
activate the automated driving system to drive the vehicle in response to determining that the system activation state is the system active state and the traffic signal phase is the green phase; and
start a first timer in response to determining that the system activation state is the system active state and the traffic signal phase is the green phase; and
disable the automated driving system in response to determining that the predetermined maximum time-period has expired.
