Hangzhou has recently introduced the green wave band where vehicles driven at specific speed on designated traffic routes will hit green light at every crossing, thus realizing non-stop travel via signal light control.
Though the green wave band enables the speedier and more efficient transportation, it is subjected to limited conditions of Hangzhou. Signal light control is applicable only under ideal vehicle speed and pedestrian flow and is subjected to the impact of such factors as pedestrians crossing streets and buses entering and leaving the bus station in the actual situation.
Now, green wave bands are seen throughout Hangzhou, and most are short-distance green wave bands in the space of 3-5 crossings, to enhance travel efficiency while guaranteeing safety. Hangzhou has provided multiple green wave band schemes at different time intervals and in different directions to effectively relieve traffic pressure in rush hours.
