Expressway is a car-only road between ordinary expressway and expressway. Taiwan Province Province has already promulgated the administrative regulations "Traffic Control Rules of expressway and expressway", and the official documents of the mainland have also distinguished the two types of expressway, but there is no special provision for expressway. On the mainland, it should be said that it includes some first-class highways and some second-class highways in backward areas. The mainland local government named expressway, the inner ring of Chongqing.
Medium speed means fast: the generalized fast in dichotomy includes high speed relative to slow speed, but the word fast does not mean high end. In the dichotomy, the name fast is medium speed, higher than normal speed but lower than high speed.
Expressway's standards are different in different places and different times. Many prefecture-level cities in the central and western regions have improved two-lane highways into two-way four-lanes, and the four-lane Lalin high-grade highway in Tibet is also expressway. In big cities with heavy traffic, six lanes are common, and eight lanes are not necessarily fast. The era of private cars is more demanding.
At present, expressway in ordinary places is generally two-way and four-lane, without guardrails; Expressway is different. Toll stations are closed all the way. Generally, it is a two-way four-lane main road with two small auxiliary roads on it, which is different in other aspects. Expressway is lower than expressway, similar to the express railway.
Relationship with expressway ("expressway" for short): Roads can be railways, highways or special areas in expressway.
Brief introduction of expressway
In the middle class
Expressway is a car-only road between ordinary expressway (general road grade) and expressway. The general design speed of expressway is about100km (80km in plateau areas such as Lalin high-grade highway). Expressway has a top speed of1.20km, which is lower than that of expressway in terms of specifications and similar to high-speed railway. Taiwan Province Province has promulgated the administrative regulations "Traffic Control Rules of expressway and expressway" for a long time, and the official documents of the mainland have also distinguished these two types of expressway, but there is no special provision for expressway.
Different standards
Expressway's standards are different in different places and different times.
In ordinary places, it is a two-way four-lane road (generally between cities in small and medium-sized cities and nearby counties, and most cities in China are small cities), but in the future, with the further development of vehicles, the road speed will slow down, and expressway needs more lanes.
In big cities with heavy traffic, six lanes are common.
Eight lanes are not necessarily fast (expressway between cities in large and medium-sized cities and nearby counties may be six lanes or eight lanes), and ten lanes are not necessarily fast in some areas of megacities.
In the suburbs of big cities, the eight lanes are generally expressway;
In the suburbs of megacities, ten lanes can be a expressway.
You should add a private car.
The emergence of the era of private cars has made old expressway crowded and turned into ordinary expressway, and correspondingly expressway needs more lanes.
Unlike expressway.
In Chinese mainland, the route of expressway is relatively open, there is no guardrail, and there is no special isolation belt between the two directions; Expressway is different. There are import and export stations guarded by special personnel and charged.
The whole process between the import and export stations is closed, with guardrails outside and isolation belts inside. Generally, it is a two-way four-lane main road plus two small auxiliary roads on the side (in some developed areas, it is six main roads plus two auxiliary roads), but other aspects are different.
& gt article 78 expressway shall indicate the lane speed. The maximum speed shall not exceed1.20km, and the minimum speed shall not be less than 60km. The maximum speed of passenger cars driving on expressways shall not exceed 120km, other motor vehicles shall not exceed 100km, and motorcycles shall not exceed 80km. If there are two lanes in the same direction, the minimum speed of the left lane is100km; If there are more than three lanes in the same direction, the minimum speed of the leftmost lane is110km, and the minimum speed of the middle lane is 90km. If the speed indicated by the road speed limit sign is inconsistent with the lane speed mentioned above, drive at the speed indicated by the road speed limit sign.
Why is medium speed called fast?
High speed is compared with low speed and medium speed. China said that the high-speed railway and the medium-speed railway are used by the Thai and Indonesian governments.
In dichotomy, fast in a broad sense includes high speed relative to slow speed (average speed), but the word fast does not mean high end. In the dichotomy, the name fast is medium speed, above average speed but below high speed.
Fast is compared with slow and constant speed (usually slow in technical system), and downward comparison means that two objects are comparing, and fast does not mean high end; High is the positioning of high-end, compared with middle and low, it is the comparison of three objects; If we compare the medium and low speed (constant speed) objects, in the velocity field, the medium speed is fast and the low speed is slow, which is faster than the low speed (constant speed). Therefore, in the dichotomy, medium speed can also be called fast, so in terms of specifications, fast is lower than high speed. In addition, the concept of eight-speed railway method in international academic circles is that the speed is lower than the high speed.
Expressway, Chinese mainland
distinguish
Article 17 of Chapter II of the Regulations on Railway Safety Management issued in August, 20 13 stipulates: "If it is necessary to build or rebuild expressway, first-class highways or expressways in urban roads, interchange facilities shall be set up, and the scheme of underpassing the railway shall be preferred." -The so-called "expressway" refers to expressway, which actually distinguishes expressway from expressway, but there is no special article in expressway.
general idea
The mainland is divided into simple highways (unpaved, equivalent to five-grade highways), ordinary highways (four-grade highways, three-grade highways and two-grade highways), high-grade highways (first-class highways) and expressway. It should be said that it includes high-grade highways and first-class highways.
There are many roads.
There are many high-grade highways in Chinese mainland, and the two-way two-lane highways in many prefecture-level cities have been improved to two-way four-lane, which is the high-grade highway.
Chongqing inner ring expressway
The mainland local government named expressway, the inner ring of Chongqing. Inner Ring Expressway was originally named Chongqing Inner Ring Expressway, and was renamed on 20 10. It is a expressway around the main urban area of Chongqing, with a total length of175km. Chongqing Inner Ring Expressway is an expressway around the main urban area of Chongqing, which is connected by the Blue Ocean Expressway and Baomao Expressway, two transit countries in the national main skeleton highway planning, which pass through Chongqing. Chongqing Inner Ring Expressway 1995 10 10 started construction in October and was completed and opened to traffic at the end of 2002. -Why did you change your name? Below specification.
Taiyuan Central expressway
Taiyuan Central Expressway is the first circular expressway in Taiyuan City. The whole line is a reinforced urban trunk road with no traffic lights on the main line.
Officially determined four-level system of urban roads
Article 16 of "Opinions on Further Strengthening the Management of Urban Planning and Construction" issued in February, 2065438+2006 in China pointed out that optimizing the road network structure of blocks: promoting the block system in new houses, and not building closed residential quarters in principle; Completed residential quarters and unit compounds should be gradually opened to realize the publicity of internal roads, solve the problem of traffic network layout and promote land conservation. Establish the urban road layout concept of "narrow road dense road network", and build a road network system with reasonable classification of expressway, primary and secondary roads and branches, so as to make the future urban roads four-grade, in which expressway refers to expressway.
Expressway, Taiwan Province Province
general idea
According to the definition of expressway in the Traffic Control Rules of expressway and Expressway, it means that "except expressway, its entrance and exit are all or partially controlled, and the center is divided into two directions, and the starting point and the ending point intersect with the plane of the main road and the secondary road, except for cars". Its English translation is "EXPWY", which is different from the "Freeway" used by National Highway (expressway).
Expressway ranks slightly below expressway. In Taiwan Province Province, it is generally divided into provincial highways and county highways (different in Chinese mainland). Those designated as provincial roads are managed by the General Administration of Highways of the Ministry of Communications, and the expressway of county-level highways is managed by the local county-level government if there are no special circumstances (such as connecting with expressway).
In addition, the service level in expressway is lower than that in expressway. For example, some expressway do not design shoulder, but still pay attention to the regional movement of vehicles. Road traffic is controlled in whole or in part. The intersections between most areas and roads are three-dimensional intersections, and a few are plane intersections. In terms of driving vehicles (right of way), in addition to cars, from June 2007 165438+ 10/,large heavy-duty locomotives with a displacement of more than 550cc can also drive in expressway, with the same level as ordinary small cars.
symbol
In Taiwan Province Province, expressway (expressway) belongs to the provincial highway level, and the original sign is the same as the general provincial highway, with a blue background and a blue frame. However, on June 65438+1October 65438+September, 2007, the General Administration of Highways of the Ministry of Communications issued a message, changing the expressway logo into a red and blue border (the actual background color is pink), and replacing it in various expressway cities one after another.
As for expressway, which is not organized as a provincial highway and managed by counties and cities, the county and city governments are responsible for the maintenance work, and there is no unified special sign.
