  Mobility is a key factor in urban life and transport network plays a vital
role in mobility. Worse transport network having less mobility is one of the
key reasons to decline the living standard in any unplanned mega city.
Transport mobility enhancement in an unplanned mega city is always challenging
due to various constraints including complex design and high cost involvement.
The aim of this thesis is to enhance transport mobility in a megacity
introducing a bicycle lane. To design the bicycle lane natural Physarum,
brainless single celled multi-nucleated protist, is studied and modified for
better optimization. Recently Physarum inspired techniques are drawn
significant attention to the construction of effective networks. Exiting
Physarum inspired models effectively and efficiently solves different problems
including transport network design and modification and implication for bicycle
lane is the unique contribution of this study. Central area of Dhaka, the
capital city of Bangladesh, is considered to analyze and design the bicycle
lane network bypassing primary roads.
