One potential advantage of cars becoming smarter is that traffic might flow better. Tachet et al. have simulated the flow of traffic and compared a system in which the first vehicle to get to an intersection has priority, versus one in which a consistent flow of vehicles is maintained. They found that slot-based interactions, in which speed is controlled so that a vehicle does not enter the intersection until there is an opening available, work best. Paradoxically, slower movement can end up being faster because vehicles can cross in batches, without clumping together. The authors estimate that this system would double road capacity and result in fewer delays
