Growth of road users in urban areas results in consequential higher interactions between pedestrians and vehicles causing delays to mainstream traffic flow. The delay caused by random jaywalking pedestrians across the carriageway is substantial. The research was conducted to study the interaction between the vehicles and jaywalking pedestrians and thereby explore the impact on the mainstream traffic due to jaywalking pedestrians in terms of delay and speed reduction. The delay and speed reduction variations are influenced by the characteristics of the crossing pedestrians and the behaviour of on-coming vehicles. Both the movement of the vehicles and crossing pedestrians on the subject lane were tracked using tracking software. Two multiple linear regression models for the delay and speed reduction of mainstream traffic were developed for the consequential characteristics. The applicability of the proposed model for each vehicle and pedestrian characteristic has been determined and evaluated based on their level of significance. If other predictors are kept constant, the delay caused by three-wheelers, cars/vans/jeeps, and trucks/lorry buses is 0.39s, 0.78s and 1.17s, respectively, whilst the speed reduction accounts for 0.32ms-1, 0.64ms-1, and 0.96ms-1, respectively.
