IT’S TIME TO DESIGN FOR SAFETY, NOT SPEED

We know how to save the lives of people walking and biking…but will we #slowthecars?

Policy makers might not understand how to design safe roads, but more problematic, they are influenced by the automotive industry, so it behooves them to prioritize motor vehicles over other road users – the most vulnerable are not driving or buying cars.

Traffic engineers by definition prioritize the level of service (LOS) of automobiles moving in traffic. In the world of traffic engineering, speed limits are determined by allowing drivers to self-govern, thereby setting speeds according to the 85th Percentile Speed – the speed at or below which 85 percent of vehicles travel. 

The numbers of deaths increases drastically with every 10mph. (See graphs/images in the article.) APCSC would like to see Asbury Park determine speed based upon safety. Most drivers know that they can exceed speed limits by 10mph, so how about #20isplenty?

 

SAFETY OVER SPEED WEEK: THERE’S ONE THING THAT ALMOST EVERY FATAL CAR CRASH HAS IN COMMON

It’s “safety over speed” week here at T4America, and we are spending the week unpacking our second of three principles for transportation investment. Read more about those principles and if you’re new to T4America, you can sign up for email here. Follow along on @T4America this week and check back here on the blog for more related content all week long.

Let’s start with a number: 49,340.

That’s how many people were struck and killed by cars while walking on streets all across the United States between 2008 and 2017. Almost 50,000 preventable deaths.

And yet, by and large, we call these crashes “accidents”. We still believe that these 50,000 deaths, and the deaths of almost 32,000 people every year killed inside of vehicles, are either just the cost of doing business for our transportation system, or were the product of bad behavior: distracted drivers, fatigued drivers, drunk drivers, or drivers not wearing seat belts.

There’s no doubt that distracted driving increases crash risk and should be punished. But distracted driving can’t explain all of these deaths. There’s one thing that almost every crash has in common, though: high vehicle speed.

When crashes occur at higher speeds, they are more likely to be fatal, especially when they involve a person biking or walking.

Big Deal: How Traffic Speeds Are Set

This is a big deal to begin making effective change in slowing traffic speeds and saving lives. #slowthecars.  First, we need to understand how traffic speeds have been set by the National Committee on Uniform Traffic Control Devices (NCUTCD) . On any given street or road speed limits have been set according to the highest speed of 15% of drivers in free flowing conditions. “85th percentile rule,” which pegs the speed limit on any particular roadway to the speeds of the fastest 15 percent of drivers in “free-flowing conditions.” So if 85 percent of the drivers stay below 40 miles per hour and 15 percent of drivers exceed it, that becomes the speed limit, even if 40 miles per hour is a bit too fast for that roadway.  The new language requires other criteria are used — like the presence of pedestrians — in setting speed limits, in addition to the 85th percentile rule.
