The invention discloses a congestion-preventing method for roads. The congestion-preventing method for roads comprises the following steps: establishing connection; pre-setting a first collecting region scope, a second collecting region scope, a vehicle speed collecting time segment value, a vehicle number, a first boundary value for unblocked vehicle speed and slow vehicle speed and a second boundary value for slow vehicle speed and congested vehicle speed by a platform; detecting and judging information of vehicle speeds and vehicle positions, uploading the information of vehicle speeds and vehicle positions to the platform; detecting and analyzing a first vehicle terminal numerical value passing through the first collecting region and a second vehicle terminal numerical value passing through the second collecting region within the vehicle speed collecting time segment by the platform, generating instructions according to the analysis result, judging the congestion conditions of roads, transmitting the instructions and the judgment result to a traffic light end and a vehicle terminal; displaying the congestion conditions of roads by the terminal; adjusting a running direction according to the instructions by the traffic light end. The congestion-preventing method and system for roads have the functions of intelligently recognizing the congestion conditions of roads and intelligently adjusting the running directions of traffic lights. In addition, the invention further provides a congestion-preventing system for roads.
