The center line of travel on a street is a road marking that separates traffic traveling in opposite directions. Typically, it is marked with solid white lines and sometimes yellow lines. A solid line indicates that you should not enter the lane, while a broken line allows you to enter. You should not cross a solid white line unless it is for certain purposes, such as making a U-turn.
You may have seen this type of marking on the roadway, although it is less common on two-way streets. These lines are designed to make it easier for drivers to stay within their own lane, especially on busy roads with multiple lanes. They also help drivers identify when it is unsafe to pass. This type of marking is most commonly found on limited access highways with divided roadways.
Roadway Markings for No-Passing Zones
A no-passing zone is a stretch of the roadway where passing is prohibited, regardless of whether or not you are in the right lane. A no-passing zone may be indicated by a single broken yellow line, a solid yellow line adjacent to the left lane, and a double solid yellow line. In this example, the no-passing zone extends from the intersection with the white line in the left lane to the center of the roadway.
The relationship between lane width and vehicle speed can be complicated, but it is generally accepted that wider lanes are safer. The reason for this is that they create a forgiving buffer to prevent vehicles from crossing over one another and can reduce the severity of side-swipe collisions. However, it is important to note that lane width should be considered as part of the overall assemblage of road design features.
Lane widths should be adjusted to match the traffic conditions in a given area, and to provide an adequate amount of space for vulnerable road users. In addition, the use of road markings, such as a solid white line with alternating broken and solid yellow lines, can be helpful in channelizing traffic.
Travel Lane Widths
Different road systems have their own rules about how wide to make a travel lane. For example, some countries have a standard of 10 feet for the width of a travel lane, while others require 11-foot lane widths. In general, the wider the lane, the slower the driving speed is expected to be.
Some researchers have even found that middle markings on a roadway can reduce the number of meeting accidents. It is believed that this is because middle lines make the road look more like a main road, and that triggers faster driving and more relaxed behavior in drivers. In contrast, it is suggested that no markings makes the road look lower quality and thus leads to more aggressive driving. However, this finding is based on a small scale experiment and further research is needed to validate these findings.
