Living in Dhaka has its drawbacks. The walkways are non existent !! Yep, even if the original design has a pathway, it is hawked by road side vendors, motor bike riders or too many holes and traps to make you glued to the pathway surface. I think , we should use the conveyor belt , all along the edge of a road moving at a slow rate , so people can get up and get off it. The energy source should be solar, the cover of this” moving” corridor have panels that get charged and make life easy.When it comes at crossing, it must stop.
You wait and cross the road safely, till you reach the next crossing. When a car leaves a residence, the belt will stop briefly for letting it pass or if it is in the middle, the driveway from each individual house would stop the car to cross randomly.
This can lead you straight to the main roads with over head bridges, this should continue like an escalator and get you down on the other side of the road. I am sure, the frequent use of inner lanes for small distance coverage can be safely done with this moving belt. Small school children would love to travel on those with their parents or friends. School going would be fun.
All over the rural land, where huge distance makes the travel tedious, it could help without much spent on transportation. We, will start seeing more people on the paths and not in the middle of roads, thus making life safer.
Although, the idea is old but we can always use it..for a better living.
