When specific implementation, frictional index detector 10 can detect the friction of highway pavement every preset time
Coefficient.When driver brakes, in the case that speed is certain, the coefficient of friction of highway pavement is bigger, then is less susceptible to out
The problem of existing whipping, skidding；, whereas if the coefficient of friction of highway pavement is smaller, then it is easier whipping occur in brake, beat
The problem of sliding.Therefore, there is above-mentioned phenomenon to reduce when driver enters behind tunnel and regulation speed is changed, be to each
Tunnel sets suitable traveling limitation speed, and the speed limit in the big tunnel of road friction coefficient can be higher than the small tunnel of coefficient of friction
Road.Controller 20 preserves the mapping relations between the coefficient of friction on road surface and traveling limitation speed；When controller 20 receives
After the coefficient of friction that frictional index detector 10 is put, can be obtained according to the mapping relations has corresponding close with coefficient of friction
The existing situation limitation speed of system, and situation limitation speed is transferred to prompting equipment 30.Equipment 30 is prompted to be arranged on outside tunnel,
Traveling for just prompting current tunnel to driver when automobile does not also drive tunnel into limits speed；Driver is receiving
To after the prompting of prompting equipment 30, will start to adjust the speed of automobile outside tunnel so that automobile is when tunnel is entered
Speed will limit below speed in the traveling, so that when tunnel is entered, even if speed is subconscious due to driver
Behavior is varied from and (usually slowed down), then automobile in traveling limitation speed below, therefore occur whipping, skid

Analysis, so as to obtain the frictional index value on road surface,
Wherein, three types are broadly divided into according to the reflection of the different objects of target object surface property：Mirror-reflection,
Diffusing reflection and direction reflection (entity reflection).Mirror-reflection refers to when mirror-reflection occurs that for opaque article its is anti-
Penetrate the energy that energy subtracts object absorption equal to projectile energy；Diffusing reflection refers to if incidence wave wavelength and rough object surfaces degree
For same order when whole object surface non-uniform reflection incidence wave, the incidence wave for inciding this surface is anti-by Lambert's cosine law
Penetrate, this reflecting surface is also known as lambertian；Actual object surface is relatively strong because shape not necessarily reflects in some directions, is referred to as side
It is a kind of reflection between minute surface and lambertian to reflection.
Determine rough object surfaces and all kinds of materials in different ripples using the different reflection type of target object surface property
The spectral response characteristic of section, different substance spectra response characteristics is also different, by the analysis to substance spectra response characteristic, then
All kinds of different materials can be differentiated.
For example, characterized when reflection of the road surface to light belongs to mirror-reflection road surface it is more smooth or have a seeping phenomenon can
Can, if surface temperature at that time is in zero degree or the following spectral response spy for having the phenomenon possibility of icing with regard to characterizing, then passing through material
Linearity curve is analyzed, as water is all very strong to 0.45 μm~0.56 μm of blue green light wavelength region and reflection, but to its all band
Absorptivity is very strong, especially has a very strong absorption band in near-infrared, middle infrared band, and reflectivity is almost nil.Bituminous paving and
Concrete spectral response characteristic is flatter without obvious peak valley, if the road surface is reflected by force, to near-infrared, middle infrared waves blue green light
Section has very strong absorption band, and reflectivity is almost nil just to can determine whether that there is ponding on the road surface, if the spectral characteristic on the road surface is flatter
Without obvious peak valley, indicate that the road surface without seeping phenomenon, prompts the road surface very smooth in itself, roughness declines frictional index
Reduce.It is so accurate to the reflection type of two kinds of light, reflectance factor and the spectral response characteristic of presentation can by road surface
The true situation for judging road surface, the frictional index on the road surface can be learnt according to table 1 below.
Table 1
As the table shows, it can determine whether that its frictional index is 2 for ponding road surface, its frictional index of ice-patch surface is 5, friction
Index is more high, represents that now surface friction coefficient is lower, road surface is more smooth, then road surface is more dangerous.
