What do you mean by special line transportation?

Special line transportation refers to the business opened by road transport enterprises according to the needs of cargo owners or market cargo flow. The customers of the former are mostly specific large and medium-sized industrial and commercial enterprises, and transportation enterprises use special vehicles between local or different places according to requirements to provide transportation services for specific shippers on relatively fixed routes. For example, between auto parts manufacturers and off-site assembly plants, and between auto assembly plants and off-site maintenance outlets, special vehicles are often used for transportation. The latter is often set between large and medium-sized cities and cargo distribution centers, serving the whole society and having fixed routes and flights. Most of them use large vans, and there are eye-catching signs such as starting and ending stations and telephones written outside the carriages, and the freight rate follows the market. The frequency density of different dedicated lines is different. Operators of special line transportation usually provide extended services of door-to-door pickup and delivery. Some large dedicated line transportation service product providers have installed GPS and other tracking and supervision systems on their operating vehicles.
