“…Not many studies have been found to address the effect of 3W as slow-moving vehicles on the traffic stream in developing countries. However, there are some studies [11,[17][18], which have studied the traffic congestion in developing countries and have indirectly considered the effect of slow-moving vehicles (SMVs) like 3W, and heavy vehicles (HVs) while analyzing the congestion or calculating heterogeneity index. Pinzke and Lundqvist (2004) [14] conducted a comprehensive study on accidents involving slow-moving vehicles on Swedish roads.…”

“…The major objective of constructing new and wider roads is usually to reduce the time of journey between any two locations, while also keeping in view the safety of the road users. However, in developing countries like India, the problem of heterogeneity or mixed traffic acts as an obstruction in achieving these objectives completely [11]. On the roads of developing countries, various categories of vehicles like two-wheelers, cars, and heavy vehicles are observed.…”

This study explores the significant role of three-wheelers (3W) on urban road traffic, focusing on the reduction in average vehicle speeds and its consequential impact on the Level of Service (LOS) of the road. Data collected from various traffic volumes reveal significant speed reductions ranging from 4 % to 35 % due to the movement of 3Ws on the road. To model this phenomenon, Artificial Neural Network (ANN) is employed. The resulting reductions in speed, induced by the 3W, trigger LOS degradation, leading to congestion and delays. A noteworthy finding is that the traffic flow naturally gravitates towards the LOS C, underscoring the substantial role played by the 3W in diminishing the overall LOS of the road. This research offers critical insights into the dynamics of urban traffic influenced by the 3W, providing a valuable foundation for traffic management and urban planning efforts.
