Thus do not advocated although following distance is excessively closely dangerous, when city vehicle is more, especially lower to the speed of a motor vehicle near crossing, closely still become a kind of general phenomenon with car.
Assuming that a kart comes immediately following a full-sized car crossing that has traffic lights, compact car usually cannot understand the change of signal lamp in time because sight line is blocked, now compact car may face awkward selection: continue to travel in tempo, usually after crossing stop line, just can see the state of traffic lights, if front truck by afterwards just in time traffic signals transfer red light to, then compact car is illegal; If sail out of at stop line front reduction gear or parking waiting large car, then likely missing once by chance because of waiting for, even therefore causing the obstruction of subsequent vehicle, knock into the back or the censure of rear car driver.
Therefore, if driver can be allowed close to when having a crossing of traffic lights, the state of signal lamp can be seen in broader scope, not only can reduce the phenomenon by mistake rushing signal lamp, also can improve crossing by efficiency, reduce block up, accident and dispute.
Once someone proposed on divisional line, install some cover traffic signal light devices again, and the program can play good effect really, but considerably increased the cost of the cost of equipment and construction, maintenance, was not therefore promoted.
Also someone advises the highway convex surface reflective mirror of installed vertical on divisional line, although also can the picture of signal lamp be reflexed in pilot's line of vision, but due to vertical reflective mirror (vertical reflective mirror, its normal or general parallel orientation parallel with road surface) can cause reversed left to right, control respectively if signal lamp is divided lane, this will be easy to the confusion causing driver to walking direction.
Summary of the invention
Inventor of the present utility model is through overtesting, find in position to use horizontal convex mirror (convex mirror normal and ground normal parallel, or both angles are no more than 30 degree) time, effectively traffic lights information can be reflexed in the driver's seat on track, and can not cause reversed left to right.
The information of traffic lights can be reflexed to position broad as far as possible near crossing for providing a kind of by one of the purpose of this utility model, and can not cause the low cost device of direction confusion.
A kind of traffic signal auxiliary device, comprises a convex reflecting mirror; Described convex reflecting mirror is installed on the region that two groups of parallel lines described by following a, b surround: on the bearing of trend of the road that a. controls at described traffic lights, centered by the motor vehicles parking line position of described road, both sides are parallel to the straight line of stop line respectively apart from two of 50 meters, described motor vehicles parking line; B., on the transverse width direction of described road, straight line or the curve that 1 meter of two of being formed is parallel to described car lane is expanded respectively in both sides to the left and right by the car lane sideline of described road; One of height height described by following c, d that described convex reflecting mirror is installed: c. is no more than 30 centimetres apart from the vertical height on the road surface of described car lane, and the convex surface of described convex mirror upwards; D. higher than the motor vehicle limit for height height of described road, and the convex surface of described convex mirror is downward; The normal of described convex reflecting mirror and the angle of ground normal are less than 30 degree.
The convex surface of described convex reflecting mirror is any convex surface that reflection ray can be dispersed or the one group plane of envelope on convex surface.
