What is the difference between trunk road and branch road?

The difference between trunk road and branch road is:Trunk road: There are two meanings, one is an electrical circuit in physics, and the other is an urban road.

Branch road: is a professional term, one is an urban road term, referring to the road branch; the second is the term of the electricity industry, which refers to the power supply branch; The third is the term of network communication, which refers to network branches.

Terminology in the electrical industry:Power supply branches.

Branchcircuit A part of the power supply system, the circuit branch is each branch of the circuit that can pass the same current, it is divided into active branch (the branch contains the power supply) and passive branch. In the circuit, the branch is a single circuit element or a series of several circuit elements, forming a branch, a branch is flowing through the same current, and each branch in the circuit is called a branch.

Trunk circuit: the route through which the total current of the parallel circuit flows; (like a tree trunk) branch: The route (like a tree branch) through which the branch current of a parallel circuit flows.

1. The magnitude of the current flowing is different. In a circuit, a trunk refers to the path through which the total current flows, while a branch refers to a branch of the trunk circuit.

2. The connected objects are different. In the circuit, the trunk circuit is generally connected to the power supply part, while the branch circuit is separated from the trunk circuit, that is, many branches are connected to the trunk circuit.

3. The connection method is different. The trunk circuit is the total part in the circuit, which is generally connected in series, while the branch circuit must be connected in parallel.

The difference between trunk road and branch road is:

First, the reference is different.

1. Trunk road: a driving lane specially built for motor vehicles from one city to another.

2. Branch road: a small road branched out from a trunk road.

Second, the focus is different.

1. Trunk roads: the main way of transportation.

2. Side road: a narrow section of the road to reach the destination.

Third, the driving rules are different.

2. Branch roads: The traffic level is lower than that of the main road, and the vehicles that are driving normally on the main road should be courteous when merging into the main road.

For large cities with a population of more than 2 million, the width of roads at all levels is as follows: 40-45 meters for expressways, 45-55 meters for main roads, 40-50 meters for secondary roads, and 15-30 meters for side roads. For large, medium, and small cities with populations of less than 2 million, the width of roads varies at all levels.

According to the Code for Urban Road Traffic Planning and Design, urban roads are divided into expressways, trunk roads, secondary trunk roads and branch roads.

The main roads are mainly used to connect important transportation hubs (national highways, provincial highways, etc.), important production areas (industrial and mining enterprises, etc.), important public places (commercial centers, schools, assembly centers, political party committees, etc.) and other important places.

The main road is mainly used for traffic functions, which is the trunk road connecting the main districts of the city, and is the main skeleton of the urban road network.

The secondary road is a regional traffic artery in the city, which serves the regional traffic distribution and has service functions, and forms a trunk road network in combination with the main Suijian Road.

The branch road is the connecting line between the secondary trunk road and the internal roads such as the residential small Jiansong area, the industrial zone, and the traffic facilities, which solves the traffic in the local area and mainly serves the function of guessing and correcting the slag.

1. Different nature: trunk road is a road connecting the trunk road and the branch road. The branch road is the connecting line between the secondary trunk road and the neighborhood road, and the auxiliary road is the distribution expressway.

Traffic roads, located on both sides or one side of the expressway, one-way or two-way traffic.

2. Different functions: branch roads are to solve local traffic problems. The main road should be the trunk road connecting the main subdivisions of the city, and the traffic function should be the mainstay. The auxiliary road can relieve the pressure on the main road.

3. The setting specifications are different: the auxiliary road should be located on both sides or one side of the main road in the ground fast, and should be located on the ground layer under the elevated road when the elevated road is located, and it should be continuously set up in the urban area. An expressway auxiliary road located in the suburbs, which can be set up continuously or intermittently.

Secondary roads should be combined with trunk roads to form a road network, play the role of collecting and distributing traffic, and have service functions. Cross-border vehicles are not allowed to pass on the branch roads, and only vehicles serving local services are allowed.

Hello kiss Xiangxun, I am happy to answer this question for you, the difference between trunk road and branch road is trunk road: the total current of the parallel circuit flows through the route of the banquet family, like a tree trunk. The electric keys on the main road can control the electrical appliances on the branch circuit, which refers to the part of the circuit that is directly connected to the power supply at both ends without passing through the electrical appliances.

Branch: The route through which the branch current of a parallel circuit flows, like a tree branch. A branch of a circuit is each branch of a circuit that can pass the same current.

It is divided into a source branch (which contains a power source) and a passive branch. In a circuit, a branch is a branch composed of a single circuit element or a series of several circuit elements, and the same current flows through a branch, and each branch in the circuit is called a branch. I hope mine is helpful to you and I wish you a happy life.
