Study Started out the study by figuring urban voids that is dilapidated spaces existing in an urban setting. Public, the people play an integral part in any space and hence the need to redefine the urban voids to develop a cohesive yet interactive Public Space which justifies its need. Seeing the accessibility, movement and environmental impact of vehicles in nature it’s imperative to look into the pedestrian flow and movement of users in a given setting. Hence in order to enhance the walkability, redefining and exploring Foot over Bridges would be undertaken in this study.

(FOBs) are such grade separated pedestrian facilities which allow easy access from one side of the road to the other, without exposing the pedestrians to any safety related issues. Some of the major benefits of providing proper elevated pedestrian facilities are safety and security to the pedestrians, along with smooth motorized traffic movement (without any interaction with pedestrians) and also low consumption of air pollution.

The videograpic survey method was used to capture the pedestrian movement data over two foot over bridges located in busy commercial locations at Ultadanga (Kolkata), Marathahalli (Bengaluru), Maligaon (Guwahati) and ITO (New Delhi).

15 Conclusion An attempt to break the monotony of the FOBs and creating an experience to promote walkability and reduce road accidents caused due to heavy vehicular usage. Retrofitting the earlier structure with possibilities of improvement in domains like lighting, habitability and thus in turn activating the space. Installing flexible active seating options in form of used tyres and using old globes as lighting shells to enhance and notch up the interactivity. Redeveloping the transition segment of the FOB, making it more interactive (Varying Shapes attach and lofting them attaches different emotions while translating to the shapes devised in different geometries), Improving the lighting systems in turn enhancing the safety and visibility thus promoting the usage, instilling green systems in the structure making the place habitable and can tackle all climatic conditions, adding pause points and active seating arrangements

16 Way Forward More form based geometry explorations can be done and stimulated via certain parameters of critical importance and then best possible design solutions can be further explored.
