bus routes, is introducing bulbs at some high-traffic stops and transfer points that have been recently renovated, notably on Roncesvalles Avenue. The first bulbs (called bumpouts locally) along Roncesvalles Avenue also accommodate cyclists, as the bike lane running parallel to the streetcar tracks would gently rise up from the road level to run on top of the bumpout. When the streetcar is boarding, cyclists have to stop behind the yellow line to allow riders on and off. There are three expected goals for these bulbs: Prevent vehicles from parking in front of streetcar stops. Increase standing room on the often restricted sidewalks at stop locations in some of the densest regions of the city. Improve safety for passengers boarding and alighting at these stops; unmodified stops require passengers to step into traffic to board/alight. The safety concerns are mostly with regard to drivers who are inexperienced at driving among streetcars in mixed traffic. Streetcar bulbs may also be beneficial at higher-capacity stops along other streetcar routes, and may be rolled out in conjunction with longer streetcars on the route.
