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?
In my city (Vienna, AT), there is a long stretch of cycleway right beside a river, parallel to one of the busiest roads (which runs one level further up): https://commons.wikimedia.org/wiki/Category:Wientalradweg
Walking is technically also allowed there, but not a lot of people do it because there are sidewalks on the top too, which lead to more destinations.
There is also a former metro viaduct that’s been converted to a cycleway, though again, walking is allowed there too: https://commons.wikimedia.org/wiki/Category:Bertha-Zuckerkandl-Weg,_Vienna
Of course the shores of the Danube and Donaukanal, including the Donauinsel, are basically (narrow) parks in which cycling is also allowed.
