Coinciding horizontal and vertical curve leads to an undesirable situation for road users controlling the vehicles and increases the potential for skidding and roll over of a moving vehicle. As the results, these regions are prone to be among the blackspots. Therefore, for these region evolution of safety condition of moving vehicle is very essential. There are various factors which affects the vehicle safety requirements at the curves, from which effects of lateral acceleration on human behavior with varying speed of vehicle is addressed in the study. Selection of the location for the defined problem must be concise and factual, therefore Kotarpur horizontal curve is used for the study which is the biggest curve of Ahmedabad city. Study shows the effects of speed variation on lateral force acceleration and human behavior as in heartbeat rate count per minute, which ultimately gives the general idea about driver’s physical and psychological situation while negotiating the curve, which may lead to accidents and indirectly increases the risk or crash factor of the curve and calls for the check of safety requirements at the horizontal curve.

Horizontal curve, Lateral acceleration, Human behavior, Heartbeat rate count, Variation in speed of vehicle.
