Recent technological advancements and the prosperity towards participating in them necessitate people and possessions to be mobile. Efficient systems are needed for enhancing the security in transportation systems. Enforcing measures to ensure road safety is of paramount importance in order to avoid thousands of deaths each year. Accidents that are caused due to human errors put not only the life of the driver at risk, but also the lives of those around him. The Co-operative Driver Support System (CDSS) proposed in this paper deals with two phases: Abnormality detection and automatic assistance. The first phase deals with the detection of drunkenness, drowsiness and abnormal heart beat, whereas the second phase alerts the driver based on the detection along with automatic control of the vehicle, if necessary. The system also sends the detected information along with the location to the driver’s caretaker over GSM. The proposed system has been implemented on an electric car prototype and tested using PIC16F877A and MPLAB IDE v8.91, which uses HiTech Compiler v9.65. © TJPRC Pvt. Ltd.
