Capacity of weaving section at off-ramp terminal of elevated expressway

Weaving section of ramp terminal is the critical section which influences efficiency of the whole off-ramp at urban elevated expressway. Capacity at weaving section determines capacity of the whole ramp. Through field survey, the paper generalized the operating characteristic of traffic flow at off-ramp terminal weaving section. Base on traffic engineering and mobile platoon theory, the thesis studied the capacity of weaving section and established theoretical model. Finally, factors influencing capacity of weaving section were studied.
