It’s really dangerous to ride a bike on the roads in my 3rd world city even walking is dangerous due to bike lanes basically being ignored, motorcycles weaving around traffic, and poor nighttime lighting.
I just thought that dedicated bike/walking only roads connecting the major parts of my city would be a big boost for safety and I think it would greatly reduce the amount of people using cars.
Has this been tried somewhere else? Was it successful?


Yes, dedicated bike lanes aren’t that uncommon, Amsterdam is famous for them. In SEA, bicycle+motorbike only roads aren’t uncommon, though its usually dictated by Right Of Way being too narrow to permit cars.
Honestly, so many hundreds of motorbikes can flow down 15 feet of road per minute, the issue is cars blocking the flow, which causes motorcyclists to behave chaoticly as they all fight to get ahead. Sections of Hanoi where they ban cars at certain hours are infinitely nicer to walk or bicycle through. In places where the motorbikes go too fast, speed bumps, lane narrowing, and other traffic devices keep them at reasonable speeds
I think that Fläming-Skate might also count, but it isn’t exactly for Bikes.
