Note 1: The row 1 of traffic_light_table means: a car goes from tl1 to tl4 (tl4 is the current traffic light). It may turn left to tl2, or turn right to tl10, or go straight to tl5
Note
2: (N) is null (no such direction, e.g. a T-Junction)

 Note 1: We set a time unit T = 30s, and divide a day (6:00 a.m. to 8:00 p.m.) into 1680T.
 Note2
: traffic_flow is a 1680-dimensional array. traffic_flow[0] represents the traffic flow from FromID to TrafficLightID at t0 (i.e.  6:00 a.m. to 6:30 a.m.)
