This paper focuses on semi-actuated signal algorithm with the affect of the crossing pedestrian-bicycle groups on left-turn vehicles at two-phase intersections. The paper analyzed the conflict characteristic of left-turn vehicles with pedestrian-bicycle groups, and made good efforts to study gap-acceptance with field data collected in Huairou District of Beijing. According to the balance principle of the left-turn vehicles arriving and departing, the new minimum green interval algorithm model is built, and it is validated with the field test. The minimum green time value result with the new algorithm is bigger than that determined with HCM2000, which means it can make up the lost time of left-turn vehicles for the affects of crossing pedestrian-bicycle groups. As demonstrated in the field study at the intersection of Yingbin Road and Fule Street in Huairou District, the timing plan calculated with the new algorithm adapted to the intersection situations perfectly. The total control delay of the whole intersection decreased 37.8 percentile, and the LOS (Level Of Service) of whole intersection improved from C to B.
