The invention discloses a signal control method and system for a road intersection, and relates to the technology of signal control. The method comprises the following steps: 1) detecting the position, speed and load factor of a vehicle; 2) judging whether the vehicle arrives at the road intersection during red light of the road intersection or not through the position and speed information of the vehicle: returning to step 1) if the vehicle arrives at the road intersection during red light of the road intersection; and switching to step 3) if the vehicle does not arrive at the road intersection during red light of the road intersection; 3) judging whether a prior passing condition is met or not: returning to step 1) if the prior passing condition is met; switching to step 4) if the prior passing condition is not met; 4) adjusting the time sequence arrangement of signal lamps at the road intersection, and enabling the signal lamps to meet a requirement that the signal lamp send a passing signal when the vehicle arrives. The method improves the overall efficiency of an urban traffic system while achieving the transportation efficiency of tramcars, and achieves the optimized configuration of road resources.
