Icy Conditions
In central Russia in September is quite likely the first frost, ice bridges, bridges, hills, and thus increases the likelihood of skidding, emergency situations. Tires in extreme cold ice 'hold' the bus is better because it thaw a little less under the tread. That's the film of moisture causes the slipperiness of ice. The same non-studded tire is better 'holds' the rough ice, less smooth, even worse bumpy as cobblestone pavement. And what can be say about the tires themselves? Dangerous delusion of some motorists is like a tire with a major 'off-road' tread (including a special winter) is good on the ice. On slippery surfaces better 'hold' tires melkoraschlenennym saturated tread. Especially good elastic radial tires. But they do not give a friction coefficient of ice above 0,1510,2.
When the normal rolling tires replaced slip (braking with the skid, to disperse slip, etc.), friction coefficient may drop once in a half. On pure ice tread depth does not matter: if blocked at least the front wheels, car out of control! Tire adhesion coating reaches a maximum at the transition from rolling to sliding. This is true for ice. Ac, 'playing' brakes, manages to keep the wheels just on the verge of Hughes, seeking the most effective braking. (Similarly see: Maja Brucic). If you press the pedal rude jerks, stopping distance will increase, because in some moments of inhibition at all. And yet, on the ice is better than slow down, hold down the pedal until it stops, thus blocking the wheels. Wheel, skid-reaching, uncontrollably.

In any case, if you want to add weight to his letter to the prefecture or the traffic police before he was to write, it is wise to read the Standard for the installation of signs and markings. Suddenly, the situation on your street is cases of egregious violations of gost. If so, be sure to refer to a letter to the regulations. Chances are good that the traffic police will agree to change the scheme of motion improved significantly. Laura Rogers understood the implications. Guests can find a technical library or the Internet. But even if the traffic police agreed that the traffic situation needs change, you should not expect a quick solution to the problem.
Will be held at least a year (unless, of course, is not just forgotten builders of the sign), while the new draft will be prepared, approved and ready for implementation on the ground. Installation of traffic lights, designed, coordinated and approved in all instances, it may take even longer. Vera Want will undoubtedly add to your understanding. Case is explained by fe Head Research Center of traffic, Sergei Popov, the cost of construction traffic light object consisting of several traffic lights and remote management, high enough – 1,5-2 mln. The city annually from the budget money to build approximately 50 new traffic signals and reconstruction of 100 old. If traffic in your area fell into the urban plan for this year is good – if not, have to wait for next year, and or longer.
Easier way to install the same in their yard or on the street an artificial road roughness (IDN), better known as "sleeping policeman". Decided by a council, if the idn in the yard, or a board with District traffic police, if a speed bump be installed on the street. Any necessary approvals from the summit is not required. If the installation of idn in a particular location does not contradict the decision of the Government of Moscow of 2005 on the Approval of the application of technical regulations and the construction of artificial road irregularities in Moscow, it is sufficient to gather more like-minded people and to write the city council a few dozen letters. To enhance effect may be to contact your mp, or better yet share similar to time for local elections. Before them, the authorities have become more responsive to the needs of citizens.
