Analysis of non-local vehicle travel and technical parameters time-varying characteristics based on video bayonet data
The second-by-second vehicle license plate record data in 2017 was obtained through the Foshan video bayonet. Taking “Foshan First Ring Road” as the boundary, the hourly-scale different vehicle types of non-local vehicles inside and outside the region, the travel and technology parameters time-varying characteristics of road types are studied.The results show that: (1) The average daily travel volume of non-local vehicles in Foshan accounts for 24.11% of the total vehicles in the city, which is similar to the proportion of non-local vehicles (23%) in large provincial capital cities. Among them, the traffic volume of heavy and light vehicles is significantly different inside and outside the “Foshan First Ring Road” (over 50%). (2) Vehicles from other places inside and outside the province are mainly from Guangzhou, Zhaoqing, Guangxi and Zhejiang, and are mainly distributed on the Guangfo connecting channel. The emission standards of non-local trucks and trucks in the province are mainly China IV (38.9%~44.6%), and the fuel type is mainly diesel (78.0%~78.4%). (3) From the point of view of hourly traffic flow, the hourly traffic volume of non-local vehicles inside the “Foshan First Ring Road” is higher than that outside the “Foshan First Ring Road”. In the daytime, the total traffic volume of non-local vehicles, and the traffic volume of non-local vehicles distributed according to different vehice types are both about 3 times that of the night-time. From the perspective of the emission standards of non-local vehicles in the province, the hourly traffic volume of China IV vehicle is the highest; at the same time, non-local vehicles mainly appear on expressways and national and provincial roads.
