Street line markings and bollards narrow the width of Einstein Avenue resulting in slower traffic patterns

Street line markings, such as these will soon narrow the width of Eldridge Avenue, between Guelph and Westbrooke, to slow traffic

Eldridge residents living between Guelph and Westbrooke will soon see white lines painted down the sides of their street, a traffic calming strategy that I first proposed on Einstein Avenue (pictured above) just a few years ago. The strategy has since proven succesful and has been deployed on several streets with speeding issues.

A recent traffic study on Eldridge, between Guelph and Westbrooke, indicated that 428 cars pass each day in both directions. While residential side streets have speed limits of 40 km/h, average speeds on this block ranged from 49km/h to 56km/h.
The majority of vehicles head southbound in order to access Ecole de la Mosaique (Westminster School to longtime residents).
Police will be checking for speeders on Eldridge this summer. Avoid the fine. Slow down.

These results prompted our engineering team to consider traffic calming options.
While some blocks have seasonal rubber speed cushions I proposed the less disruptive parallel lines that visual narrow the road and typically. Humps slow down emergency responders and annoy as many residents as are pleased by them. Traffic calming lines provide similar results with less annoyance.
What do you think about these traffic calming measures?
