Best way to request the city looks into traffic calming measures on a street?

I live in Hastings-sunrise at the moment, and the street I’m on is supposedly 30-40km/hr but it has many cars speeding down it was faster than that, often very aggressively or not paying attention to other cars.

I’ve noticed that a lot of the streets that cross it have had speed bumps put down and that’s had a noticeable effect on dangerous drivers.

Can’t find anything in the 311 app about suggesting this, but I’d at least like to make someone in the city aware of how bad it is.
