A Discretionary Lane-Changing Decision-Making Mechanism Incorporating Drivers’ Heterogeneity: A Signalling Game-Based Approach
Table 5
Solutions in three equilibriums.
| Type | Strategy | Condition | The sender (CAR-TF) | The receiver (CAR-E) | Aggressive | Conservative |
| Separating equilibrium | S | NS | If S, then W; if NS, then C | | NS | S | If S, then C; if NS, then W | Not available |
| Pooling equilibrium | NS | NS | If NS, then C/W | | | S | S | If S, then C | |
| Semiseparating equilibrium | S | | Update information using p and x. If S, then ; if NS, then C |
| | NS | Update information using p and x. If NS, then ; if S, then W |

S = signalling; NS = not signalling; C = changing lane; W = waiting.
