A Critical Review on Capacity Estimation Approaches for Mixed Traffic Conditions in Developing Countries

With the advancement in vehicular technology, this modern world is facing unique challenges in traffic scenarios. A spectrum of problems and diversity in capacity estimation is observed, as researchers have focused on the issue of quantifying and tackling complex vehicular interactions in heterogeneous traffic for decades. Thus, findings like the inability to follow a lane based approach in traffic management in mixed traffic interactions, given the conditions of road geometrics, necessitated the course of research in developing countries to estimate capacity through a thorough understanding of every deviation from existing homogenous lane disciplined models and methods. Developed countries like the USA, Australia, etc. have integrated their researches into a fine standard manual such as the Highway Capacity Manual (HCM), to guide engineers and highway planners. The type of homogeneous or heterogeneous traffic experienced on the roads of developed or developing countries itself draws the line between standards and methods adopted for traffic planning and management in the respective scenarios. Resorting to the basics of capacity evaluation and yet accounting for the deviations observed in mixed traffic from standard ideal traffic conditions, numerous works have been conducted worldwide. This paper aims to consolidate the literature marking important evolutions of mathematical methods and logical concepts of estimating highway capacity and its parameters in mixed traffic specific to uninterrupted flow facilities in developing nations. An important aspect of the paper is summarizing the gaps in the available literature which can be looked upon for further research.
