When the left turn volume exceeds a threshold, the traffic demand will exceed capacity on the approach. 當左轉交通量超過(guò)一個(gè)定值時(shí)，進(jìn)口道的總需求交通量超過(guò)通行能力。
By comparing the two formulas, the paper concludes that moving automatic block can reduce the train headway and improve the transportation capacity. 通過(guò)對兩公式的比對，得出了移動(dòng)自動(dòng)閉塞系統能夠縮短列車(chē)的運行間隔，提高線(xiàn)路的通行能力。
