Vehicle Blind Spot Monitoring Phenomenon Using Ultrasonic Sensor

This paper evaluates a conceptualization of Vehicle Blind Spot Monitoring System (VBMS), which performs a more effective approach in eliminating blind spot of the driver. The newly developed smart blind spot monitoring system simply focusing on an advancement of the preceding work, along with compromising user compatibility and cost-effectiveness. Compact design, reliable and low-cost that contributes to a highly affordable safety feature are the flagship of this new system. Components selection is the main role in constructing an inexpensive blind spot detection system in the present work. Thus, Arduino UNO R3 model and HC-SR04 ultrasonic sensors were employed for the VBMS system due to reasonable market price. Plus, the ultrasonic sensor has demonstrated a remarkable performance in the past blind spot detection system application. Concerning easy installation as well as maintenance on any vehicle, the VBMS is designed as a compact device which assembles the main control unit and sensory partsin a single body to be located at the bottom of the side mirror. Meanwhile, the hazard-warning signal is separately located at the passenger compartment for easily visible by the driver. The angle and sensing range of sensors are both adjustable but vital as their projections define the blind spot limit accurately by characterizing low to a high potential hazard. At the end of this work, a complete VBMS functional prototype of has been establish which effective for real traffic on-road experimentation, with various conditions specified (static, various speed, and overtaken). From the data collected, all targets of the present work have been attained regarding monitoring phenomenon shown by the new-built system. Both pros and cons of VBMS are discussed for further improvement ideas on product developmen

Modeling Discretionary Lane Changing Decisions for Connected Vehicles Based on Fuzzy Logic

Lane changing is one of the most complex tasks during driving. Advances in vehicle technology seek to help drivers during the lane change maneuver. Researchers have conducted many attempts to address this issue. However, most of these attempts have not focused on actual driver behavior using advanced vehicle technologies. Among those advances is the vehicle-to-vehicle (V2V) communication which promises safer and more efficient driving operations. This research seeks to fill in this gap by conducting an experiment in a driving simulator environment simulating V2V communication during a lane change maneuver. The experiments allow a better understanding of driver behavior during lane changing maneuvers. First, a literature review was completed to assess studies that focused on understanding and modeling discretionary lane changes. Then a pilot study was conducted with a small sample on a driving simulator to obtain a fuzzy logic membership function. Then a large sample was tested for the study. Adjustments were made to the model and performance measures were analyzed. A t-test was conducted to evaluate any significant differences between the two conditions with and without V2V communication. The results showed that drivers were more willing to accept smaller gaps under connected environment conditions than without V2Vcommunication. Also, the implementation of V2V communication was found to help drivers make the lane changing decision faster. The overall initial speed was reduced under the connected environment

Reducing Side-Sweep Accidents with Vehicle-to-Vehicle Communication

Side-sweep accidents are one of the major causes of loss of life and property damage on highways. This type of accident is caused by a driver initiating a lane change while another vehicle is blocking the road in the target lane. In this article, we are trying to quantify the degree to which different implementations of vehicle-to-vehicle (V2V) communication could reduce the occurrence of such accidents. We present the design of a simulator that takes into account common sources of lack of driver awareness such as blind-spots and lack of attention. Then, we study the impact of both traditional, non-technological communication means such as turning signals as well as unidirectional and bidirectional V2V communications
