Tag: Traffic Signs

Don’t get too excited, but it’s YET ANOTHER idea about stop signs! Maybe this blog should be renamed “Worst Traffic Signage Proposals.”

 

Background:

When a driver comes to a stop sign, they don’t intuitively know whether it is a two-way or an all-way stop. The difference is important, because a lot more diligence is required at an intersection where cross traffic does not stop.

The issue:

See Figure 1: if you add a bunch of trees, parked cars, buildings, and other visual obstructions, it can be very difficult to determine whether the other cross streets have stop signs or not.

Fig. 1: In this bleak gray-and-white plain, it’s easy to tell that the cross traffic does not stop, but in reality there will be a number of trees / cars / buildings that obstruct the driver’s view.

Proposal:

Lanes of traffic that specifically do NOT stop could be marked with lines on the ground (see Figure 2), similar to a crosswalk.

Fig. 2: This green arrow (which extends through the intersection, as seen above) is a visual indicator to inform drivers that cross traffic does not stop.

The only downside to this would be that people might start to assume that the lack of lines would mean “cross traffic DOES stop.” In that case, an alternative formulation could be made where the lanes that do stop are specifically marked ini an obvious fashion (see Figure 3). (Although existing intersections do occasionally have a white line and the word “STOP” painted on them, this marking is very inconsistent and is not at all visually obvious).

Fig. 3: A) In order to prevent drivers from relying too much on “lack of any marking = cross traffic DOES stop,” we could invert the scenario and explicitly mark the lanes of traffic that WILL stop (orange dots here). B) The blue arrow is another possible example of a more aggressively obvious pattern to indicate lack of traffic stopping.

Conclusion:

You should buy some stock in companies that sell road-suitable paint, and then propose this idea as an amendment to your state’s constitution (assuming that is a possibility).

PROS: May reduce accidents at two-way-stops-misinterpreted-as-four-way-stops, which might be a major cause of residential car crashes (probably someone knows this, but not me).

CONS: Doesn’t work very well when there is snow on the roadway. Additionally, paint requires substantial maintenance to keep visible; roads might need to be repainted a lot more often, for unclear benefit.

One Bicyclist’s Quest to Fix Traffic Congestion Forever

The issue:

Traffic laws are made with the idea that everyone is driving a car. In the US, four-way stops are all over the place, at almost every intersection. In a car, this isn’t a huge burden, since it requires no human effort to stop and then accelerate again.

But with a bike, this requires significant expenditure of energy.

(In the absence of cross-traffic, it is also rare to see any vehicle actually come to a complete stop.)

The idea:

Bicyclists could opt-in to a “EXTREME BIKING” program in which the following two traffic law changes are made:

1) A red light becomes a “STOP + YIELD” together — the bicyclist must stop at the light and must yield to any cross traffic. In other words, cross traffic (going through a green light) continues to have unimpeded right-of-way.

2) A STOP sign becomes the rarely-seen YIELD sign. A bicyclist can pedal right through it, but must stop and wait if there is any cross traffic.

All other traffic laws remain the same.

But: Drivers are generally averse to bicyclists playing fast-and-loose with traffic laws. In order to gain support among drivers, the program will be opt-in, and every bicyclist who wishes to abide by these new rules must put an “EXTREME BIKING” sticker on their bike.

In a collision with a bike with the EXTREME BIKING sticker on it, the bicyclist will be assumed to be at fault unless evidence implies otherwise.

Ideally the sticker should be something evocative of the danger, like a skull on fire or pirate flag of some sort.

Conclusion:

PROS: Recognizes the unreasonableness of requiring bicyclists to stop so frequently. Should increase average bike speed. May result in amazing Youtube dash-cam montages of disasters. Will increase the number of available organs for transplant.

CONS: None whatsoever!
