As mentioned in the early section about three types of communications: V2V, V2R and V2P communications, when, they are grouped together, autonomous connected vehicles are created and will change the way of transportation and enhance ITS in the future. For example, the Department of Transportation in the USA, implementing the new rules and regulations mandatory for V2V communication technology, which will contribute positively to improving vehicular traffic management and reducing the large number of traffic accidents. As V2V communication provides safety services in VANET, it can help drivers by augmenting their cognizance of their surroundings. The V2V communication technology can not only inform drivers about any approaching hazards, but can also help to prevent accidents happening ahead in the first place. This technology will support blind turn, blind spots, poor visibility, foggy weather and even fatigue. Government and private organizations are planning to develop embedded applications for experimenting and simulating in several road configurations with the connected vehicles in the world.
Workload, Distraction, and Automation

Building from the examples provided in Figure 6.3, Table 6.2 illustrates the impact of a variety of automation technologies on specific driving subtasks. As shown, the set of driving subtasks, here based on Brown (1986), incurs a certain amount of workload in normal driving conditions. As new technologies are implemented (e.g., DSFs, Levels 1–2), workload for each of the subtasks might increase, decrease (in varying degrees), or remain unchanged. For example, the addition of a blind spot monitoring system can reduce the visual, cognitive, and manual demands associated with collision avoidance by providing drivers with additional information regarding the proximity of nearby vehicles. In examining these relationships, it is important to consider where decreases in workload on one subtask are associated with increases on another task. For example, the implementation of adaptive cruise control (ACC) and lane-keeping assist (LKA) are logically associated with reduced demands for steering and velocity control, but with increased demands for vehicle and system monitoring when these systems are in operation.
Driver vehicle interfaces and older adults

Older adults tend to have reduced range of motion making it more difficult for them to turn their head to see vehicles that may be in their blind spot. Therefore, as discussed in Chapter 5, blind-spot indicators near the side-view mirrors can be particularly helpful for older drivers. These typically provide a visual alert when a vehicle is close to or is in the driver's blind spot, and some systems also provide an auditory alert if the driver starts to change lanes toward a vehicle in the blind spot to facilitate collision avoidance. The addition of an auditory alert will be particularly important for older people, as the reduced useful field of view (UFOV) characteristic of older people (see Chapter 3) could reduce the ability to detect the signals from the blind-spot detection system.
Effects of blind spot monitoring systems on police-reported lane-change crashes
Published in Traffic Injury Prevention, 2018
Blind spot monitoring systems, which are also referred to as blind spot detection, blind spot warning, lane-change alert, side blind zone alert, or side-view assist, notify drivers when a vehicle in an adjacent lane is in their blind spot, typically with a visual alert in or near the corresponding side-view mirror. Some also warn of rapidly approaching vehicles in the adjacent lane. For simplicity, these systems will be collectively referred to as blind spot monitoring systems throughout this article. Warnings may intensify by blinking or beeping if drivers engage the turn signal when the system detects another vehicle. Systems were first offered as optional equipment on Volvo S80, V70, and XC70 models in model year 2006 but are now more widely available. In model year 2017, blind spot monitoring systems were offered on two thirds of new vehicle series as optional (57%) or standard (9%) equipment (Highway Loss Data Institute [HLDI] 2016e).
A novel context-aware system to improve driver’s field of view in urban traffic networks
Published in Journal of Intelligent Transportation Systems, 2022

This paper presents a novel Advanced Driver Assistance System (ADAS) using computer vision approach (background subtraction algorithm) to improve drivers’ contextual and spatial awareness of their surrounding. In this regard, a system is designed to detect objects in the blind spots (see Figure 1) and send real-time spatial and contextual information of surroundings to the drivers for an efficient and informed decision-making solution to mitigate the risk of the collision. To do so, a distributed system architecture is developed including camera, processor and local database as a Road Side Units (RSUs), and the process sends notification about detected vulnerable road users such as pedestrians, cyclists, animals, and human-operated vehicles, or even AVs nearby.
Motorcycle crashes potentially preventable by three crash avoidance technologies on passenger vehicles
Published in Traffic Injury Prevention, 2018
Blind spot detection systems use radar, ultrasonic, or video camera sensors to detect other vehicles present in the equipped vehicle's blind spot. Systems typically illuminate a warning light on the corresponding side mirror or A-pillar whenever a vehicle is present, and some systems issue an additional warning if they detect that the driver intends to change lanes in that direction when an adjacent vehicle is present. Some systems intervene to try to prevent lane changes when a vehicle is detected in the blind spot. Blind spot systems have been shown to reduce lane-change crashes by 14% (Cicchino 2017b) and property damage liability insurance claim rates by 2–11% (HLDI 2012, 2016a).
