Footpath friction factors are those activities and physical obstructions on the footpath that influence its effective usage. Footpath friction includes presence of trees, electric poles, roadside vendors, and vehicle parking on footpath. Few roads in Bengaluru city were selected to study the reduction in the width of effective carriageway due to diversion of pedestrians from the footpath into the carriageway because of footpath friction. A few footpath stretches of significant vehicular traffic and pedestrian volume were selected in Bengaluru city. Field studies were carried out to record footpath frictions, pedestrian volume, pedestrian speed, and vehicular speed on carriageway. The studies indicate that footpath friction reduced the carriageway width to about 8–27% due to pedestrians walking along footpath entering into the carriageway. More than 33% pedestrian choose carriageway over footpath. Trees along the footpath were found to be the highest contributing friction factor in reducing the width of footpath compared to other friction factors. It is also observed that the average vehicular speeds along the carriageway reduced by 71% due to significant footpath friction.
