Using Allstate claims data, Allstate analysts use a predictive model to compare each city's collision frequency
when factoring in its population - resulting in large jumps for dense cities like New York City (up 92 spots), Jersey City (up 74 spots), Chicago (up 49 spots) and Miami (up 47 spots), when compared to the list that doesn't take population density into account.
The latter influence the collision frequency
of particles and bubbles: adhesion is only possible when air bubbles come into contact with hydrophobized mineral particles.
The 14th annual Allstate America's Best Drivers Report ranks the 200 largest cities in America based on collision frequency
. The average driver in America will experience a collision approximately once every 10 years, according to Allstate claims data.
where [[omega].sub.p] is the plasma frequency, v is the electron collision frequency
, [omega] is the angular frequency of the propagating electromagnetic wave, n is the electron density, e is the electron's charge, m is its mass, and 0 is the permittivity of free space.
Research focused on safety commonly describes how work zones affect collision frequency
[15-18], severity [19-23], or both [24-28].
In the first 18 months of installing the SmartDrive solution on all company-owned trucks, Fraley & Schilling reported a 67 percent decrease in its collision frequency
The vibration frequency of the free mass is varied during the collision process, and the average collision frequency
of the free mass is about 520 Hz.
According to their study, the amplitude of transmitted THz wave is obviously modulated by the electron density profile, electron collision frequency
and electron temperature.
Figures 2 and 3 show that property damage frequency climbed to 3.59 percent in the first quarter of 2016, while collision frequency
was 5.95 percent.
A Knowsley council spokesman said: "There is clear evidence of the effect of reducing traffic speeds on the reduction of collisions and casualties, as collision frequency
is reduced at lower speeds and where collisions do occur there is a lower risk of fatal injury.
It was explained in the following way: the addition of PGPR to the food emulsion is not only increased the viscosity of the continuous media but also got adsorbed over the surface of the droplets resulting a decrease in sedimentation rate, collision frequency
and an increase in electrostatic as well as steric stability as expected by Equations (1, 2) .
Based on Allstate's claims data, the report ranks America's 200 largest cities in terms of collision frequency
to identify which have the safest drivers, including how these cities rank when precipitation, whether ice, rain or snow, is a factor.
