  Cooperative driving at isolated intersections attracted great interest and
had been well discussed in recent years. However, cooperative driving in
multi-intersection road networks remains to be further investigated, because
many algorithms for isolated intersection cannot be directly adopted for road
networks. In this paper, we propose a distributed strategy to appropriately
decompose the problem into small-scale sub-problems that address vehicle
cooperation within limited temporal-spatial areas and meanwhile assure
appropriate coordination between adjacent areas by specially designed
information exchange. Simulation results demonstrate the efficiency-complexity
balanced advantage of the proposed strategy under various traffic demand
settings.
