Abstract

Multiple interventions and innovations in geometric layouts on the road are done to reduce the travel time, re- duce traffic congestion and increase the mobility flow. One of these improvements is the introduction of protected U-turns at junctions. With the implementation of this technique, the through moving traffic is given priority as they traverse without any obstruction. Such a system is beneficial if the designer aims to design the junction sig- nal free and it lessens the travel time to some extent. Although it is practical there are certain implications and consequences that arise with the execution of such an unconventional layout. Pakistan currently utilizes this idea in designing their roads currently. The goal of this paper is to highlight the potential consequences as well as the advantages of this arrangement. In order to develop a better understanding of these phenomena, some existing examples are given of Lahore in this paper to pinpoint the pressing issues at large i.e. obstructions to pedestrians, land acquisition issues in urban areas, need to provide pedestrian bridges which ultimately increase the cost of the project. The contribution of this research will aid the geometric designers and traffic engineers to take multiple considerations in the planning/designing the stage from all ends before instigating this pattern on roads.
