At the beginning of 2011, the Ministry of Transport, the Ministry of Public Security, the State Administration of Safety Supervision and the Ministry of Industry and Information Technology jointly issued the Notice on Strengthening Dynamic Supervision of Road Transportation Vehicles, requesting that the departments of transportation, public security, safety supervision and industry and information technology at all levels set up a coordinating mechanism, strengthen departmental collaboration, and form a supervisory synergy, so as to ensure that all chartered buses for tourists, buses for shuttle routes and road vehicles specializing in transporting dangerous chemicals, fireworks, firecrackers and explosives (referred to as “two passenger vehicles and one hazardous vehicle”) are installed with satellite positioning functions. The requirement is to strengthen departmental cooperation, form regulatory cooperation, and ensure that by December 31, 2011, all chartered tourist buses, class III or above buses, and road vehicles specializing in the transportation of hazardous chemicals, fireworks and firecrackers, and explosives for civil use (referred to as the “two passengers and one hazardous” vehicle) are installed with satellite positioning devices with the function of driving records. With the rapid development of China's road transportation industry, the number of “two passengers and one dangerous” road vehicles has increased significantly. Therefore, in order to improve the efficiency of vehicle transportation and strengthen the capacity of vehicle transportation, the basic information management of vehicles, driving routes and driving status monitoring, safety operation management, national network and joint control management and other issues have arisen. Tianmai Technology has developed two passenger and one hazardous solution for this purpose.
