at the time of holidays, the most congested sections of the city center is not necessarily the CBD, but fast and from a variety of roads and highways between cities. Is supposed to be faster, more efficient road, but was a lot of traffic on the aggregated form is a few kilometers short as a few hundred meters long congestion.
In this regard, some friends are explained toll traffic barrier the reason, some friends say is not high travel speed butterfly effect caused. Different point of view, naturally, different low efficiency of highway traffic view. Therefore, many owners and shipping industry considers necessary for the current highway driving speed to be optimized.
highway plays an artery in urban road network effect, quickly and easily reach the city each Office, help reduce vehicle fuel consumption, improve circulation efficiency and personnel goods. However, the speed limit is too low for this can go faster, more efficient traffic can only be accumulated in the highway. In the last year, the Ministry of Transport regulation and standardization process of unreasonable speed limits are.
“cliff-style” undoubtedly affect vehicle deceleration in highway driving safety, but at the same time, appropriately raise the speed limit for the highway traffic efficiency also have a role.
For example, under construction Hang Shao Yong Expressway is the first Article superhighway. According to construction requirements, Hang Shao Yong Expressway will learn from Germany’s Federal Highway, the Italian highway design standards for construction. The two countries freeway traffic requirements to be higher than the current rate of domestic demand; most of Germany’s highway speed limit and did not request, and the highest highway in ItalySpeed limit of 150km / h. However, after a lot of information yet Shao Hangzhou and Ningbo Expressway understood as limited-speed highway. If the read-Hangzhou and Ningbo Expressway introduce requirements for speed part, it did not indicate future implementation of limited speed.
in different countries the highway speed limit is divided
[ 123] in other words, Shao Hangzhou and Ningbo Expressway just learn German and Italian highway construction standards, with the road infrastructure to achieve maximum speed limit of more than 120km / h in. Looking at the world countries, the highway speed limit of more than 120km / h, not many countries, such as France maximum speed limit is 130km / h, the maximum speed limit for the United States 140km / h. As Shao Hangzhou and Ningbo Expressway in the future will set the maximum speed limit to how much there is still no specific announcement.
here is to build the highway speed limit higher, but the highway speed limit is on the other side of the globe, said Nature is the first highway construction in Germany. Recently foreign media reports, the German environmental organization demands on the highway speed limit to curb the impact of vehicle emissions on the environment.
and had advocated “Free driving for free citizens” concept for the German club ADAC GM’s limited-speed highway argue that this has not expressed a clear position on the issue of opposition from environmental groups.
In our opinion, the high-speed rate limitation Germany Highway is the driving enthusiast’s paradise, to experience many performance vehicles traveling at high speed pleasure. In fact, open-speed autobahn is the result of experience after a long running trade-offs. Early in the 1970s oil crisis, the German government beganTemporary speed restriction measures applied, the highway speed limit set at 100km / h. However, the community and the automobile manufacturing industry have expressed strong opposition. According to reports in March 1974 the German magazine “Der Spiegel”, due to the impact of temporary speed limit policy is applied, when car sales in January only 197,340 Percentage year.
By the 1980s, environmental groups because of acid rain and deforestation appears, once again questioned and dissatisfaction with the unlimited-speed highways. In the environmental groups view, if the rate of discharge of harmful substances from 100km / h increased to 130km / h, the car will probably double. But if the maximum speed is set to 100 or 80km / h, the vehicle can be made in Germany was reduced NOx emissions from 200,000 to 300,000 tons per year.
The federal government launched a large-scale experiment a speed limit 100km / h with the aim of impact on emissions and environmental aspects of the measurement speed is reduced. After the experiment, the federal government refusing to take a mandatory limit on the highway, on the grounds that emission reductions after the spin-down will not have an impact on the loss of forest meaningful. So in 1987, after the speed limit all the test area have been canceled.
At present, Germany does not face the highway and again He questioned the speed limit. The matter comes from the German government about a year ago commissioned a third party to write a new report on climate change, which is covering the future of mobility and vehicle development. The specific content of the recommendations, called for the cancellation unrestricted highway, and to generally 130 km / h speed driving, and banned all diesel vehicles entering the city.
economic level determines the superstructure, whether or not the highway the speed limit issue, China’s Shao Yong super highway to Hangzhou as the answer. By improving highway design standards, allow the vehicle to build a basis of high-speed traffic, while big data and intelligence, factors that reduce congestion, improve traffic efficiency to achieve the goal. The German driver is based on good citizenship education, supporting the rationalization of road construction, to create a limited-speed highway in order to promote economic development.
both have advanced their merits, but also have their own uniqueness, and therefore can not simply think that Germany does not require open-speed road and our need ideas evaluated. Of course, fans naturally want to be more open-speed highway driving but only if we need to raise the level of education and to be able to carry the stage, only the subsequent development at all.
