The evolution of roadways, initially designed for high-speed mobility, has led to a critical urban challenge as these corridors have become an integral part of the expanding city. City Sprawl and Urbanization has caused a shift in the high mobility corridors that used to be outside the city limits to function as major urban arterial access in the city. This shift poses a serious safety concern on these “Urban Highway.” The existing design standards and guidelines are operational as individual typologies but fail to accommodate the dynamic nature of these corridors demanding a change in the approach. 
The study focuses on the illustrative example of the SG Highway, where the intersection of high-speed travel and urban access has given rise to safety, accessibility, and mobility issues. In a concerning revelation, the SG Highway was among India’s top ten road crashes sites in 2023 by the Indian Road Crashes Data Management System (Irad/eRAD) of the Ministry of Road Transport and Highways (MoRTH).

Aim, Objectives and Research Question

Establishing the Extremes- Towards a New Model

The gray zone of guidelines

Meta-themes and Element categorization

Testing on a pure highway to check if the tool gives accurate results

Testing on a pure urban road to check if the tool gives accurate results on the other end of the spectrum

Site Testing- The YMCA to Karnavati Club Stretch is leaning more towards the mobility side of the spectrum

Site Testing- The Iskcon to Pakwan Junction stretch is leaning more towards the central portion of the spectrum. Some of the reasons for this include a BRTS corridor passing by, major attractions like the Iskcon Temple and high pedestrian footfall along with grade separated junctions and priority to vehicular movement

Site Testing- The TGB to Zydus Junction is also found to be leaning more towards the center or the spectrum. Some of the reasons for this includes metro stop and other street infrastructure elements along with highly separated movement and managed access

Mitigation strategies are provided as a base for designing a set of guidelines from both IRC and HCM.
