Today, I passed by the White House City Road and found that the middle of the road was installed with an isolation guardrail. After the installation, the road that originally felt very wide suddenly felt narrow, why did it feel this way? I think it's mainly because after installing the guardrail, you can't cross the middle line and go directly to the opposite side. The area of action has shrunk by half, of course, it feels narrow.
The road with the central guardrail installed has a feature, that is, it must be wide enough, at least two-way four lanes, otherwise if you install a guardrail on the two-way two-lane road, a car nests, and the car behind cannot bypass from other lanes, it will block the entire road, and the picture is simply not too spectacular.
Although the guardrail is installed, it is clear that the planning is not perfect, and some details can be done better. For example, this crosswalk, the zebra crossing is a guardrail, next to the isolation pile, directly take the zebra crossing is not passable. Just a little bit worse, the isolation pile directly hit the zebra crossing can't it? This side has to shovel off the zebra crossing and repaint it, which is a waste of manpower and paint.
There is also here, there is no reservation in the middle of the mouth to turn around, from the opposite side to the White House City vegetable market to buy vegetables of the old iron or from the express police around a large circle of hundreds of meters and then turn back, or directly from the front of the traffic lights to cross the road and retrograde for tens of meters. Retrograde is certainly not possible, and it is not very convenient to go around.
There are also traffic lights here, using double solid lines, theoretically, if you have a red light in front of you, you can't turn around here. Originally, the traffic time given by this direction was short, if you can't turn around, although the road is wide, you are really afraid of traffic jams at that time. I hope to change it to a dotted line with a red light to turn around, which is convenient for the masses.
