Herd immunity for traffic safety in mixed automated traffic: what if cars could not crash!?

Figures & data

Figure 1. Example of CAVs protecting HDVs, a) the prior situation b) accident situation with HDVs, c) accident avoided situation with CAVs.

Figure 2. Demonstration of risk transmission and herd immunity in traffic.a) interaction between vehicles, b-d) transmission of risk with only HDVs, e-f) transmission of risk in mixed traffic showing the benefits of herd immunity

Figure 3. Final number of infected vehicles at the end of 100 time steps, average over seeded runs.

Figure 4. Case depiction: a) the prior situation b) accident situation with HDVs, c) accident avoided situation with CAVs.

Figure 5. Depiction of vehicle trajectories for the case in Figure 3. Red denotes a CAV. The black box denotes a place where herd-immunity improves safety.
