I really like that it tracks speed. Being able to tell officials that a significant portion of drivers are speeding seems like a great first step when requesting stop signs or speed bumps.
Speed bumps are such a shitty solution to speeding. I’d prefer speeders to speed bumps.
Personally I'd rather get hit by a car going 10mph than 30. Even better would not be getting hit at all, and lower speed means more time to react.
Giants trucks and SUVs are getting more and more prevalent and don’t have to slow down as much. This trend doesn’t appear to be slowing down. You can’t make the bumps big enough otherwise it’s going to wreck cars. People also haul ass immediately after getting off the bump, so you end up with lovely brake squeals and engine sounds for a few hundred feet of decreased speed. They prematurely wear suspension components and brakes and lead to increased fuel usage.
They’re shit and I’m so glad I’ve moved out of the southern US and back into snow country where speed bumps simply can’t exist. I don’t know why speeding through residential areas is so much less prevalent in the north, where there are far fewer speed bumps, but I love it.
None of that agrees with my own experience. Plows don't seem to have any trouble with them around here, but they still manage to keep traffic slow.
Ideally we'd have streets engineered for traffic calming, but that would take an incredible amount of time and effort in dense areas, so I'll take the speed bumps.
Why not 1mph then?
I'd rather your car get fucked up than a person.
Dope, I’ll get a large SUV or truck to replace my small hatchback so I don’t have to slow down at all. Larger vehicles improve pedestrian safety right?
Speed bumps are a bandaid being used as a solution. They fuck with emergency vehicles, encourage rapid braking and acceleration, incentivize getting a larger vehicle, reduce gas mileage, and create noise from braking and acceleration. I’ll take literally any other traffic calming measure over a speed bump.
They’re a hell of a lot better than nothing.
They're actively worse than nothing.
Speed bumps are pretty much the worst option for speeding. Lane narrowing, adding curves, and lane diets should be preferred, and you can try them out at similar costs with plastic bollards or even cones. That being said if you want speed bumps, install elevated sidewalks instead.
I mean those are all somewhat difficult to add in residential neighborhoods...
The problem is the $200+ sensor. I'd love to be able to track this sort of data, but not until doppler radar prices drop.
It’s possible to still track speed using a video feed instead. You just have to know the distance between two static points within the videos frame. Time naught = passes first static point, time final = passes second static point.
Velocity = distance / time
Although I’m not sure how or if this would impact the battery life of the device.
Yeah, but I'm not allowed to just video tape the street all day long. A Doppler radar that gives me data to argue for a permanently installed speed control on the other hand would be fine
Really? At least where I'm located, you're allowed security cameras anywhere there isn't reasonable assumption of privacy.
In Germany you are not allowed to permanently film public space, that includes streets and sidewalks
Damn! I didn't realize the radar was so expensive.
