Even though the traffic systems in developed countries have been analyzed
with rigor and operated efficiently, the same does not generally hold for
developing countries due to inadequate planning, design, and operations of
their transportation systems. Because of inherent differences between internal
infrastructures, the systems deployed in developed countries may not be
amenable to developing ones. Besides, the traffic systems of developing
countries are not well-studied in the literature to the best of our knowledge.
For example, it is yet to explore how a developed country's lane-based traffic
flow would perform in the context of a developing country, which generally
experiences non-lane-based traffic. As such, by using our newly developed
traffic simulator 'RoadBird', we investigate outcomes of both lane-based and
non-lane-based traffic from the contexts of both developing and developed
countries. To do so, we run simulations over real road topologies (extracted
from the GIS maps of major cities such as Dhaka, Miami, and Riyadh) considering
different scenarios such as lane-based or non-lane-based flows, homogeneous or
heterogeneous traffic, with or without pedestrians, etc. We also incorporate
different car-following and lane-changing models to mimic traffic behaviors and
investigate their performances. While the lane changing dilemma remains an open
research question, our experimental evidences indicate: (i) lane-based
approaches will not necessarily perform better in the case of currently-adopted
non-lane-based scenarios; and (ii) non-lane-based strategies may benefit system
performance in lane-based scenarios while having heavy mixed traffic.
Nonetheless, we reveal several new insights for on-road experiences both in
developing and developed countries.
