These influences can be divided into two states: friction and block interference. Based on the data of interference of bicycles on vehicles' driving in typical road section in Beijing, this paper quantitatively analyzes the velocity changing tendency of vehicles under different interference, velocity distribution frequency, and critical transformation of different interference state. The friction and block interference coefficients are also worked out, which are useful to compare interference degrees under different road conditions.
