This dataset encompasses the road travel ranking information of hazardous cargo transport vehicles under networked joint control and management in Maoming City since 2022, which is derived from the connected and joint control module of the Maoming City Transportation Holiday Smart Travel Support and Guarantee System. The dataset includes three core attributes: vehicle type, road section name, and prefecture-level city.

Based on the safety evaluation of road transportation of dangerous goods, this dataset analyzes the travel trajectories and regional distribution of two types of passenger vehicles (passenger coaches and tourist buses) and hazardous cargo transport vehicles (officially referred to as "two passenger and one hazardous" category) across the city using GPS data. It visualizes the top 20 most frequently traversed road sections and hot spot distribution maps of the city in a cartographic format, and enables real-time monitoring and early warning for high-risk road transport vehicles. The data can support traffic comprehensive law enforcement with checkpoints and reasonably guide the public's travel.
