一、概况自一九七九年全国开展国道和干线公路交通流量观测以来,全国已建立起连续式观测站154个,间隙式观测站6,982个,观测国道达102,900多公里,占国道总里程的95%,已初步形成了全国性的网络。目前,我国交通量的调查工作从数据收集到数据的处理,基本上还是采用人工操作的方式。观测精度受人员业务水平、外界环境等多种主客观因素的影响而难以控制。
I. Overview Since China started the traffic flow observation of national highways and arterial roads nationwide in 1979, there have been 154 consecutive observation stations, 6,982 interstellar observation stations and over 102,900 km of observation national highways, accounting for the total national highway mileage 95%, has initially formed a national network. At present, the investigation of traffic volume in our country from the data collection to the data processing basically adopts the manual operation mode. Observational accuracy is difficult to control due to the influence of various subjective and objective factors such as the level of personnel’s business and the external environment.
