the experiments for operating vehicles demonstrate that the degree of accuracy and reliability of integrated navigation and positioning system, compared with gps / dr navigation and positioning system, is enhanced, vehicular operation efficiency and security are far and away strengthened and the thoroughfare capacity is improved . as consequence, traffic congestion can be moderated with effect and the automation of transportation management and the intelligence of the vehicular drive will be realized 汽車試驗表明:采用地圖匹配的方法來校正gps/dr的定位誤差,其定位精度及可靠性比gps/dr定位有所提高,車輛運行效率和安全性也大大改善,提高了通行能力,有效地緩解了交通擁擠狀況;從而為實現(xiàn)交通管理“自動化”以及車輛行駛“智能化”提供了技術(shù)支持。
the experiments for operating vehicles demonstrate that the degree of accuracy and reliability of integrated navigation and positioning system, compared with independent gps navigation and positioning system, is enhanced, vehiclular operation efficiency and security are far and away strengthened and the thoroughfare capacity is improved . as consequence, traffic congestion can be moderated with effect and the automation of transportation management and the intelligence of the vehicular drive will be realized 跑車試驗表明:采用組合定位技術(shù),其定位精度及可靠性比單獨gps定位有提高,車輛運行效率和安全性就會大大改善,提高了通行能力,可有效地緩解交通擁擠狀況;從而可為實現(xiàn)交通管理“自動化”以及車輛行駛“智能化”提供技術(shù)支持。
