Summary and future prospects for road pricing: open research areas, future work and conclusions

The chapter states that the road traffic schemes will not remove congestion on a sustainable basis, if implemented independently of other measures. The third and fourth certainly have their benefits, though the jury is still out on the impact of autonomous vehicles, but none of them are a complete solution. So the real issue is how to achieve the public (and hence political) acceptability of road pricing and create conditions that are favourable for its implementation.
