Base on analytic hierarchy process to analyze reasons and measures for lorries causing traffic accident

Lorries have usually caused traffic accidents in recent years. The reasons for traffic accidents were analyzed, and a series of measures were given. The Analytic Hierarchy Process (AHP) model for traffic accidents were made up. All weight factors to reduce lorry causing traffic accidents were calculated. As a result, the best way to decrease the number of traffic accidents is to improve pre-post training and engagement qualification. It´s a reasonable advice for the traffic governor to guide the lorry.
