Coefficient of travel speed variation 行程速度變化系數(shù)
Abstract : in this paper , traffic data collection techniques for traffic flow guidance systems are analyzed . a modified licence plate recognition method , which is suitable for travel - time investigation in busy streets , is proposed 文摘:討論了交通流誘導(dǎo)系統(tǒng)的交通流量、行程時(shí)間和行程速度的采集技術(shù),提出了一種改進(jìn)的牌照識(shí)別法,該方法適合于交通流密集路段上的交通數(shù)據(jù)采集。
