ADOPTABILITY OF ADAS AMONG INDIAN CAR DRIVERS

Abstract

Nowadays, road traffic crashes are one of the challengeable issues in the whole world. Almost 90% of road traffic crashes are happening due to human errors. ADAS systems are designed to minimize or even mitigate the human errors. Regarding to the literature review, if the ADAS system is used properly, the crashes will be decreased by 70%. This study deals with the perception, acceptability and prevalence of ADAS features among Indian car drivers. ADAS is a new introduced technology in India. It is found that there are several theories of technology acceptance model such as Theory of Reasoned Action (TRA), Technology Acceptance Model (TAM), Theory of Planned Behavior (TPB) and Unified Theory Acceptance and Use of Technology (UTAUT). From the literature, a conceptual technology acceptance model, known as Unified Model of Driver Acceptance (UMDA) model was found suitable to understand the driver acceptance toward ADAS. This study identifies nine most influential factors on behavioral intention toward ADAS. Nine main factors are perceived usefulness, attitude toward the behavior, perceived ease of use, subjective norm, perceived behavioral control, compatibility, endorsement, trust and safety effectiveness. In case of India, safety effectiveness of ADAS is added in the model to check its impacts on actual use of ADAS. The moderate factors are age and gender. 288 samples are collected from all over India through a questionnaire survey which is designed to gather the relevant information. Descriptive analysis is selected to analyze the data and a non-parametric test (chi-square) is done to statistically prove the relations between main and moderate factors. From the descriptive analysis, Indian driver’s knowledge, perception, and prevalence of ADAS features are investigated. Furthermore, level of false alarms, overall driving comfort, time of explanation the ADAS features by the salesperson, level of understanding from the explanation and time preferred to explain the ADAS are also examined. According to statistical test, it has been found that, age affects safety effectiveness, attitude, perceived ease of use, perceived behavioral control, compatibility, endorsement and trust toward ADAS. Furthermore, it is found that gender affects perceived usefulness, perceived ease of use, compatibility, and perceived behavioral control.
