In India, diverse traffic flows are common with mixed vehicle types and no dedicated lanes. Urban areas suffer from poor lane discipline as vehicles interact both longitudinally and laterally, affecting traffic flow and service levels. This study in Nagpur city examined factors affecting lateral gap: velocity, road width, vehicle combination, and level of service (LOS). Peak-hour video graphics surveys on various roads were conducted, and regression analysis showed significant impacts of vehicle type, speed, road width, and traffic conditions on lateral gaps. The lateral gap increases with the speed and reduces with poor LOS. Mixed vehicle pair combinations had the smallest gap, while CAR-CAR had the largest. The gap increases with the road width.

摘要

In India, diverse traffic flows are common with mixed vehicle types and no dedicated lanes. Urban areas suffer from poor lane discipline as vehicles interact both longitudinally and laterally, affecting traffic flow and service levels. This study in Nagpur city examined factors affecting lateral gap: velocity, road width, vehicle combination, and level of service (LOS). Peak-hour video graphics surveys on various roads were conducted, and regression analysis showed significant impacts of vehicle type, speed, road width, and traffic conditions on lateral gaps. The lateral gap increases with the speed and reduces with poor LOS. Mixed vehicle pair combinations had the smallest gap, while CAR-CAR had the largest. The gap increases with the road width.
