All along, with the development of self-driving cars, people generally hope that they can ease traffic congestion and improve the efficiency of traffic operations. However, experts from the University of California have stated that the impact of autonomous vehicles on traffic will be minimal or even negative.
In the afternoon on the 5th, Beijing time, according to foreign media reports, autopilot is currently a hot topic, and many companies that develop this technology claim that the future self-driving cars will use space more efficiently than ordinary cars and relieve traffic congestion more effectively. And reduce traffic accidents.
However, a study by U.S. experts found that while self-driving cars may make people's future commuting more enjoyable, they will not relieve traffic congestion.
Some industry executives, including Google co-founder Sergey Brin, have advocated that self-driving cars will eliminate accidents caused by human error and effectively relieve traffic congestion.
But in an interview with BusinessInsider, Lew Fulton, co-director of the Institute of Transportation Studies at the University of California, Davis, said that the impact of self-driving vehicles on traffic will be minimal or even negative.
He said that self-driving cars will not solve the congestion problem unless a pricing system is devised to prevent the emergence of zero-occupant vehicles, the so-called “zombie carsâ€.
Fulton said: "We are particularly concerned about zero-occupant vehicles. This scenario is especially likely to happen when privately-owned vehicles are owned by individuals."
For example, many companies are programming auto-driving cars so that they are deeply interested in running errands or picking up and transporting their own goods, but this may lead to a multiplication of zero-occupant vehicles, which in turn increases traffic congestion.
The Massachusetts Assembly has proposed a tax on driverless cars to prevent the emergence of "zombie cars." According to this proposal, a zero-occupant vehicle pays at least 2.5 cents for every mile it takes.
At the same time, as companies design more comfortable autonomous vehicles, consumers may choose to live farther out of the city because they can sleep or rest in the car on commuting roads. However, this will also increase the flow of traffic entering and leaving the city during peak hours, thereby aggravating congestion.
In addition, Fulton also said that even if the future self-driving vehicles are operated as part of a ride-sharing network such as Uber, it is still possible to increase traffic congestion.
This is because without the driver's cost, the automatic driving "special car" charges such as Uber or Lyfts will become so cheap that people will prefer to take these vehicles by themselves rather than share with others.
Fulton said: "I think we need some sort of pricing mechanism to stop zero-occupant vehicles and penalize single-occupant vehicles."
Some cities have already taken action and do not encourage people to travel by themselves. California and Colorado have already installed high-charge lanes, single-occupant vehicles must be paid to use, and charges will increase during peak hours.
A communication Cable Assembly is a Wire Harness used to transmit signals. A communication cable consists of a plurality of mutually insulated wires or conductors to form a cable core, with a communication line with a sealing sheath on the outside. Some are also equipped with an outer sheath outside the sheath. There are various laying methods such as overhead, direct burial, pipeline and underwater. According to the structure, it is divided into symmetrical, coaxial and integrated cables; according to functions, it is divided into field and permanent cables (underground and submarine cables). The communication cable has a wider transmission frequency band, a larger communication capacity, and less external interference, but it is not easy to repair. It can transmit phone calls, telegrams, data and images, etc.
Communication cable assembly can be classified mainly by cable types and applications
According to the type of cable, communication cables are classified as follows:
1. Single-conductor: refers to the most primitive communication cable, a single-conductor loop, with the earth as the regression line.
2. Symmetrical cable: a loop composed of two identical conductors under ideal conditions.
3. Coaxial cable: The inner and outer conductors on the same axis form a loop, the outer conductor surrounds the inner conductor, and the two are insulated at the same time.
Then they are classified according to the application as follows:
1. Long-distance cable: The transmission distance is long, and it is generally multiplexed. Most of them are directly buried in the ground. In a few cases, they are installed overhead or installed in pipelines.
2. Cables in the city: the wires in the cable are "paired and paired", and the number of pairs is large. Generally installed in the pipeline, a small number of urban cables are attached to the building or installed overhead.
3. Office cable: mainly refers to the communication cable used in the telecommunications office, generally installed on the distribution frame, and some are installed in the wiring trough; the office cable is used between the transmission equipment and the switching equipment in the telecommunications office, and other Inside of intra-office equipment. In order to prevent fire inside the telecommunication bureau, it is sometimes necessary to add a flame retardant sheath to the bureau cable.
