A highway network, road and bridge network, and city road and bridge network; the highway network consists of rectangular highways (1, 2, 3, 4), transverse roads (7, 8) and longitudinal roads (5, 6); the rectangular highways (1, 2, 3, 4) comprise a front highway segment (1), a back highway segment (2), a left highway segment (3) and a right highway segment (4); the longitudinal roads (5, 6) comprise a forward longitudinal road (5) and a back longitudinal road (6); the transverse roads (7, 8) comprise a leftward transverse road (7) and a rightward transverse road (8); the connections between the longitudinal roads (5, 6) or the transverse roads (7, 8) and the highway segments are T-junctions (9, 10, 11, 12); the T-junctions (9, 10, 11, 12) have a traffic circle (13) therein; the road and bridge network consists of a main road network and branch road networks. The highway network and the road and bridge networks enable vehicles to bypass each other during traveling, without meeting each other or causing traffic jams. |
