Sarajevo-based architect, Muzafer Osmanagić, in order to solve traffic congestion in Sarajevo, has proposed a study called "Eco Energy 2010-2015", idealizing a subway system underneath the bed of the river Miljacka.
In 2011 Sarajevo International Airport had 599,996 passengers which is more than all of the airports in Bosnia-Herzegovina had together and 6.5% more than in 2010.
