Listening to the radio while driving with navigation, is there a navigation prompt for the speed mea

Prompted, the radio will be quieter when navigating the prompt.

1.New driving station: Listen to the wonderful programs as you like, and carefully integrate with the navigation voice.

2.New electronic dog: electronic eye data covers 300 cities across the country, goodbye fines.

4.New Driving Score: PK your driving skills with friends, your driving skills will be proven here.

5.Traffic condition reporting: one-click reporting, built by hundreds of millions of netizens, the most accurate real-time traffic conditions.

6.Urban congestion points: covering 2,300 congestion points in 20 cities, a must-see when you go out.

Tencent Map, formerly known as Soso Map. Users can use the map to query the geographical location of banks, hospitals, hotels, parks, etc., and through the street view of Tencent Maps, users can realize online virtual tours, and can also understand the surrounding environment of the place before going to a certain place, so as to find the destination more easily.

There are many functions: mobile phone navigation, street view map, location query, route query, real-time traffic conditions, surrounding query, TA function, zero traffic map, mobile map, voice navigation, real-time bus.

It's so handy, I'm using this right now. Hope it helps!

Interval speed measurement, single-point speed measurement, and flow speed measurement are the three speed measurement methods we often encounter when driving at high speeds. Do you know the difference between them?

A single point of velocity measurement is a point above high speed. There will be an iron box in the middle of the road, and a speed camera will be arranged in the iron box, or there will be a row of gantries with speed cameras arranged on it. This kind of speed measurement point, because it is fixed, can accurately remind you that the speed measurement point is ** when you usually use navigation.

In single-point velocimetry, there is another form of flow velocity measurement, also known as mobile velocimetry. This speed measurement is random, and the traffic police will get a speedometer and place it at a random point on the highway. This kind of speed measurement has the characteristics of single-point, uncertainty, fluidity, etc., which cannot be avoided through navigation.

In equipment, interval velocity measurement is more complex than single-point velocity measurement. There will be a set of speed measurement equipment at the beginning of the interval speed test, and there will also be a set of speed measurement equipment at the end of the interval speed test. As long as the car enters the starting point of the interval test, and then records the time when the car leaves the end point of the interval speed test, the average passing speed can be accurately obtained by dividing the length of this speed measurement distance by the time spent, so the interval speed measurement is more reasonable.

On highways, if the accelerator is not carefully controlled at the foot of the speed measurement point, the speed of the vehicle may exceed the measured megaspeed value, which is considered speeding. Although I ran four or five hundred kilometers on the highway and ran strictly according to the speed limit, just when I passed the single speed measurement point, in order to get rid of the car next to me, there was an instantaneous acceleration and overtaking behavior, which happened to be recorded, even if it was speeding.

If it's an interval speed test, you don't have to worry about this embarrassment. If you want to get rid of the car next to you in the speed test zone after passing the speed test at the speed limit of 100, you can drive faster at this time. At the moment of overtaking, it doesn't matter that there may be speeding.

As long as you overtake and change lanes to the middle lane and then slow down, as long as the average speed of the entire section does not exceed the maximum speed limit set by the speed limit, there will be no speeding violation.

The interval speed measurement greatly relieves the driver's nervousness at high speeds, gives the driver more adjustable zones, and reduces the probability of false violations. It is more reasonable to take the average value of interval velocity measurement than the average value of single-point velocity measurement. Although an instantaneous speeding at a point in the interval speed test will not be recorded as a speeding violation.

However, Brother Meow suggested that you should never exceed the speed limit when driving at high speeds. Zone speed measurement simply gives the driver an adjustable zone. In this section, you must ensure that you drive safely and never exceed the speed limit.
