It's a crap idea rushed and not well thought out, a better proposal would have been to initiate circular matatu routes in town where matatus get in and out without parking or turning.
Matatus entering from Globe roundabout to go through Tom Mboya picking and dropping passengers and exit through Race course road, Desai road and Pangani.
Matatus entering through Landhies road to go through Haile Selassie picking and dropping passengers and exit through Uhuru highway and onwards to Mombasa , Lang'ata and Lusaka roads.
Matatus from Ngong road to Railway terminus picking and dropping passengers without parking and exit through Haile Selassie.
That's a better and implementable solution, the traffic cops have only to make sure matatus are constantly moving.
