What is Transportation Design? What is the professional background and application background of tra

Function is used as the basis for selecting highway grades and determining design goals. To determine the grade of a highway, it should first be clear whether the function of the highway is a trunk highway or a distribution highway and whether it is necessary to control access, etc., and then according to the initial highway grade of traffic volume, and then determine the design speed and roadbed width in combination with the terrain and traffic composition.

When the design traffic volume is between the first-class highway and the expressway, the proposed Hufu land construction highway is a trunk highway should be selected as a highway, and the proposed highway is a collection and distribution highway should be selected as a first-class highway. Considering that there are practical problems in the operation safety of the first-class highway, low traffic efficiency, and difficulty in reconstruction and expansion, when the traffic volume is between the first-class highway and the Zhili highway, it should be considered in combination with the highway function.

Trunk roads should be selected as secondary and above roads.

In recent years, the consensus has gradually formed a professional course that integrates the basic concepts, basic knowledge and basic skills of traffic engineering. The basic concept of traffic design: traffic design is a professional course that integrates the basic general knowledge and basic skills of traffic engineering that has gradually formed a consensus in recent years, mainly for the traffic system.

Characteristics and problems, based on the concept and results of urban and transportation planning, the design of the current and future construction of the transportation system and its facilities.

Summary. The basic principles of traffic design include the principle of lane balancing; speed balance principle; The principle of spatio-temporal resource balance.

The basic principles of traffic design include the principle of lane balancing; speed balance principle; The principle of spatio-temporal resource balance.

How do you understand the relationship between the three basic principles?

Meaning of traffic design: Based on the concept and achievements of urban and traffic planning, using the basic theories and principles of traffic engineering, with the purpose of traffic safety, smoothness, efficiency, convenience, shouting and environmental coordination, and taking the "resources" of the traffic system as the constraint of the traffic system, the existing and future construction of the traffic system and facilities are optimized and designed, and the best plan to improve the traffic is sought.

The difference between a traffic planner and a traffic engineer is:

1. In terms of the profession of learning: traffic planner is a liberal arts major, and traffic engineer is a science major.

2. From the perspective of work: traffic planners are engaged in design work, and traffic engineers are required for design and construction.

3. The traffic planner is the design of the general direction, including the relationship between the road direction, the city, the countryside, the natural conditions, and the regional traffic configuration. Traffic engineers engaged in design are more specific traffic design, such as the setting of bridges and scattered town beams, the selection of road structures, the selection of road materials for Qiyou roads, and the treatment of local road sections.

There are many differences, and a few words on the Internet must not be clear.

This book is a textbook for the 11th Five-Year Plan of General Higher Education. The book is divided into 10 chapters, systematically expounding the basic theories and methods of traffic design and their application techniques, including: introduction, the theoretical basis of traffic design, traffic problems and their characteristics analysis, traffic design basis and conditions, urban road traffic design, bus traffic design, hub traffic design, parking lot (library) traffic design, traffic safety design, traffic language system design, traffic design technology evaluation and analysis, etc.
