When cities across the world expand and people’s mobility rises, so does the number of cars on the road. As a consequence, officials are facing an increasing number of problems in terms of road traffic control. As a result, there are more road chaos, more deaths, and waste. Despite the advancement of advanced traffic control systems and other vehicle-related technology, accidents remain a leading cause of death. As a result, a standard method for injury prevention must be created. For example, in most metropolitan environments, traffic congestion may be alleviated by route planning in real time. However, developing an efficient route planning algorithm to achieve globally optimal vehicle control remains a challenge, particularly when drivers’ tastes are taken into account. Also, intelligent transportation systems (ITS) are an effective implementation of Cyber-Physical Systems (CPS) that enhance driving safety by advising drivers of hazards with alerts in advance. The efficacy of warnings must be assessed to facilitate ITS communication. This analysis aimed to create a scale to assess warning usefulness, or how effective a warning is at avoiding accidents in general. The Verbal Alert Utility Scale (VWUS) was validated in a virtual driving environment using a driving simulator. The VWUS had decent split-half reliability with a Spearman-Brown coefficient of 0.873, according to the reliability report. The significant prediction of safety benefits suggested by variables such as decreased kinetic energy and collision rate confirmed the predictive validity of VWUS in calculating the efficacy of verbal alerts. This scale is a better way to test the general effectiveness of verbal alerts in transmitting related dangers in intelligent transportation networks than doing experimental experiments. This scale can be used to enhance the nature of ITS alarms and thereby increasing transportation safety. The scale’s uses in nonverbal alarm scenarios, as well as the new scale’s shortcomings, are also discussed.
