交通工程学（Traffic engineering） Traffic engineering Description: Traffic engineering is the basic theory of traffic engineering research and development, is derived from the road engineering is a relatively young discipline, it brings people, vehicles, roads, environment and energy, and some aspects of the traffic in road traffic this unity, to find a solution to the traffic capacity and traffic accidents, at least, fastest, largest shipping costs the most provinces, minimal environmental impact, the lowest energy consumption of the transportation system planning, construction and management, so as to achieve safe, rapid, economic, convenient, comfortable, energy-saving and low pollution. Characteristics of traffic engineering disciplines: 1. Systematic 2. Comprehensive study of traffic Engineering disciplines: Engineering (Engineering), regulations (Enforcement), Education (Education), Energy (Energy) and Environment (Environment), therefore, traffic Engineering disciplines are often referred to as five E disciplines. 3. Crossover 4, social 5. Prepreexistence 6. Dynamic The traffic engineering discipline is a comprehensive discipline that is developing, which brings people, cars, roads, environment and energy into a unity from the perspective of transportation The history of traffic engineering development: Traffic engineering was established in the 1930s. In 1930, the American association of traffic engineers was established, which marked the birth of the traffic engineering discipline. In the initial stage, we mainly discussed issues such as reducing traffic jams, ensuring traffic safety and traffic management. In the 40s, traffic planning was noticed. In the 1950s, the relationship between people, cars and roads in road traffic was studied, and traffic flow theory was established. In the 1960s, computer control signals, data processing and planning were applied to traffic engineering, and the problem of traffic pollution was studied. Introduction of systematic engin
