A study of network roads of Yazd shows that although the roads of these networks are suitably widened and serviceable to the different vehicles, the number of centeral streets such as Imam Khomeini (between Imam sadegh and Abozar square) are resolved or nearly resolved and are considered the critical exes. Yazd city has 22 crosses of 2, 3 and 4 times. The average time of green distance in all phases is 26 seconds. The overall average time of one cycle of road light for 2, 3 and 4 times is 55 , 77 and 135 seconds respectively. At present there are 200 active buses in 48 bus lines and 140 taxies in 6 taxi lines.
