JP2006194053A - Temporary stand-by place for left turning vehicle at intersection - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To secure a place for allowing temporary stand-by for a plurality of left turning vehicles waiting for pedestrian's crossing a pedestrian crossing at an intersection until the completion of pedestrian's road crossing in the intersection after the completion of the left turning of a vehicle to achieve safe and smooth traffic passing and improve various problems that cities have by reducing traffic congestion by following vehicles and improving a wide view of the road. <P>SOLUTION: Positions of the pedestrian crossing and a signal machine for the pedestrian crossing among elements constituting the intersection are provided apart from the center of the intersection when compared with current installation positions without changing an existing signal control mechanism to use a scope of a newly created play zone as the temporary stand-by place after the completion of the left turning of left turning vehicles and allow following the vehicles to pass the intersection safely and smoothly. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a traffic system that contributes to improvement of various traffic problems in an intersection.

  In general, the intersection that has been restored is an area where various types of movement such as cars, two-wheeled vehicles, pedestrians, etc. coexist, regardless of the minimum range. As such control media, pedestrian traffic lights and vehicle traffic lights are used as sidewalks and roadways, and progress indicators.

Among typical traffic accidents at intersections, there are many that are caused by a left turn. Countermeasures to reduce traffic accidents, such as accidents involving motorcycles due to large vehicle volumes, as well as pedestrian injuries caused by vehicle defects that have become a social issue in recent years, are simply vehicle safety management and driver attention. There is a limit to relying solely on increased obligations.
In particular, the current situation is that the fear of an increase in the lack of duty of caution for the driver cannot be denied in the environmental changes in the vicinity of the driver's seat where mobile phones have been rapidly recovered in recent years and the additional functions are diversifying.

In addition, various problems caused by traffic congestion caused by a left turn cannot be neglected.
According to the traffic rules currently seen mainly, straight and left turn of a vehicle and crossing by a pedestrian crossing in the same direction as the straight direction of the vehicle are performed at the same time, but a left turn car goes straight on a pedestrian crossing this pedestrian crossing. Because it is waiting in the left turn combined lane, it will hinder subsequent straight vehicles, and there are also two-wheeled vehicles such as passing straight through the intersection and two-step right turn, and the risk tends to increase according to the number of left turn waiting vehicles, It is often seen that natural congestion occurs when the following vehicles continue in a chain.

  However, in order to make various large-scale improvements such as three-dimensional intersections, it cannot be easily implemented from the viewpoints of financial and traffic congestion, economic activities, adverse effects on surrounding areas, and so on.

  The problem to be solved lies in the positional relationship that causes various obstacles when the pedestrian crosses the road and the vehicle goes straight and turns left. In particular, the length of the waiting time for the left turn unit vehicle during pedestrian crossing has a great influence on the number of left turn completed vehicles within the possible left turn time.

Means for Solving the Invention

  The present invention has the main feature of providing a play space for waiting for a left turn vehicle in an existing intersection in order to enable smoothing of a diagonal line that goes straight and turns left.

The invention's effect

  The wide-area intersection including the present invention provides a pedestrian's safe waiting, road crossing and vehicle in the intersection in order to provide a left turn vehicle waiting place by a play area space generated by sliding the position of the pedestrian crossing at the intersection. As a result, the road traffic safety is improved by reducing the blind spot and improving the outlook at the intersection, and shortening the waiting time of the following vehicles and reducing the number of waiting vehicles. There are advantages such as reduction of fuel consumption, reduction of air pollution sources such as nitrogen oxides, reduction of heat island phenomenon, etc., which can improve and correct various problems at intersections.

  Within the existing intersection, the purpose of the safe crossing of pedestrians and the smooth passage of passing vehicles can be implemented with a typical number of parts without impairing the existing road configuration and traffic regulations.

FIG. 1 shows an embodiment of the present invention.
The pedestrian crossing is slightly separated from the center of the intersection compared to the existing location, thereby creating a new play area within the intersection.
The pedestrian traffic light also moves with it, but the operation control of the pedestrian traffic signal and the vehicle traffic signal is maintained.
At general intersections, both pedestrians and straight turn left vehicles are signaled under the same traffic light control. Therefore, because of the continuity of pedestrians that are both continuous and intermittent, left-turn vehicles need to wait temporarily, but since there is this waiting place, pedestrians after multiple left-turn vehicles complete a left turn. It is possible to wait temporarily until the road crossing is completed. Thereby, the influence which the following vehicle etc. receive from the present can be eased several steps.

  The parking prohibition rule at the intersection in the current traffic rules eliminates the need to display parking prohibition areas with a red paint display that is currently in effect in some areas, eliminating the cause of motorcycle slippage in rainy weather, and safety of the intersection Increase. Using this play area space, it is possible to provide a dedicated stop line for a motorcycle as required.

  Because the target effect can be obtained by slightly sliding the position of the current pedestrian crossing, it can be constructed in a low budget, in a short period of time regardless of the many public works, and the impact on traffic congestion during construction should be minimized. Is possible.

Protect pedestrians with right-angled guardrails individually at the four corners of the intersection, and install warning signs for pedestrian crossings as necessary to warn vehicle drivers and improve the safety of corners at the intersection. It becomes possible to raise.
Furthermore, as the concept of corner lots at intersections expands, stopping and improving land value decline, revitalizing land use by increasing fixed assets, facilitating the disposal of non-performing loans by banking institutions, and the new flow of pedestrians We can expect the possibility to spread to various economic effects such as activation of store utilization.

It is explanatory drawing which showed the implementation method of the wide area intersection containing this invention. Example 1

Claims (1)

  At existing intersections, without changing the signal control mechanism, install the pedestrian crossing and the pedestrian crossing signal installation position farther away from the intersection center than the existing position, and the resulting play area space in the intersection, Used as a temporary waiting place for left turn vehicles waiting for pedestrians crossing the pedestrian crossing, ensuring smooth traffic such as the following vehicles in the straight lane combined with left turn and the safety of the pedestrian crossing users, various problems of the intersection due to congestion reduction Left turn vehicle temporary waiting area with features that can be expected to improve and reduce heat island phenomenon, reduce gasoline consumption by reducing idling cars, correct pollution problems by reducing exhaust gas, and even revitalize land use The intersection where was installed.
