Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] Such as Figure 1 to Figure 5 As shown, the present invention simultaneously provides a traffic safety facility at a roundabout at an urban-rural junction, which includes: the lower edge and the top of the roundabout curb stone along the driving direction, painted at intervals of 2 to 4m. line; set up concrete isolation piles at intervals of 8-16m along the outer side of the roundabout curb at the roundabout; set 4-6 at equal distances along the road along the roadside edge line and along the side slope at each corner of the roundabout Concrete isolation piles; pedestrian crosswalks set up on the road near the roundabout; steel fixed isolation piles installed at the near end of the vehicle's forward direction at the edge of each side lane...

Abstract

The invention provides a traffic safety facility for a roundabout of a rural-urban continuum and a design method of the traffic safety facility, aiming to improve the speed perception and the direction perception of a driver when the driver drives at the roundabout of the rural-urban continuum and improve the visual cognition capability of the driver to pedestrians crossing the street and barriers in a roundabout range. The facility comprises strip vertical face marker lines at the lower edge and the top of a roundabout annular-island curbstone; concrete separation piles are arranged between the outer side edge line of the roundabout annular-island curbstone and the outer side edge line of a road; concrete separation piles are arranged between the road side edge line of each road of the roundabout and a slope edge line; steel fixed separation piles and LED (Light Emitting Diode) lamp poles are arranged on pedestrian crosswalks and the lane edges at the sides of the roundabout, corresponding to the pedestrian crosswalks. The method adopts a low-cost road marker line and visual induction system and does not relate to a large-scale road infrastructure, so that the investment is small, the construction is easy and the effect is rapid to realize; the driving safety of the roads of the rural-urban continuum can be improved.

Description

technical field [0001] The invention relates to the field of traffic safety design at intersections, in particular to a traffic safety facility at a roundabout at an urban-rural junction and a design method thereof. technical background [0002] Accidents frequently occur at intersections. The intersection is the concentrated place of vehicle turning and the conflict zone of various traffic flows. Vehicles are likely to squeeze, collide and collide with each other when passing through the intersection, which is likely to cause traffic congestion and traffic accidents; among the proportion of traffic accidents in various road sections in the national statistics, accidents near the intersection and within the intersection area accounted for the largest proportion of accidents. 64% of the total, frontal collision accidents accounted for 23%, an average of 0.39 people were killed or seriously injured in each accident; side collisions accounted for 46%, and an average of 0.24 pe...
