According to the Traffic Performance Index, which measures congestion on a scale of zero (smooth) to 10 (snarled), Beijing hit 8.5 during the evening rush hour on Wednesday and 9.1 on roads within Third Ring Road at 7 pm.
為了缓解道路交通压力,北京市呼吁市民尽量选择public transport(公共交通)出行,对私家车先后实行了license-plate lottery(车牌搖号)和traffic restrictions based on the last digit of license plate numbers(尾号限行)政策,另外,还考虑对車輛收取congestion fee(拥堵费)。
