Physiological Study of Blood Pressure and Heart Rate at Road Intersections

Intersections are the critical road network where two or more roads meet and are connected. There were two types of intersections, which are signalized and unsignalized. Next, the physiological factor of a driver is one of the indicators for the condition of the driver. A condition such as drowsiness and fatigue that could affect the focus and performance of drivers during driving could be the major cause of traffic accidents. Besides that, stress and tension could lead to a temporary increased in blood pressure and heart rate of drivers. In this research, drivers aged 20 to 30 years old have been selected and the driver’s blood pressure and heart rate have been sampled by using OMRON digital wrist blood pressure monitor before, during, and after driving, including their driving speed. Thus, the focus of this study was to study Physiological behavior while driving throughout a signalized intersection. An analysis by using the Regression Method to obtain the r-squared value has been applied to determine the correlation level between both of the variables. According to the sampling software, 36 participants are required to be tested. But due to Movement Control Order (MCO), only six participants were successfully sampled. A signalized T-junction of Jalan Persiaran Kayangan near Universiti Selangor (UNISEL), Shah Alam has been selected, and by the data obtained, we could determine the driving behavior of drivers in a real-life situation.
