ITS Solutions and Accident Risks: Prospective and Limitations

Abstract

This article investigates the prospective and limitations in the application of potential intelligent transport system (ITS) functions to reduce accident risks, using a cause-treatment relationship. The main causes of road accidents are described and appropriate ITS solutions (including advanced driver assistance systems and advanced traveller information systems) are presented as countermeasures. Anticipated impacts are discussed and indicate that several ITS have the potential of improving road safety and addressing specific accident causes. However, attention is required on particular aspects of their implementation as they may trigger adverse effects by imposing behavioural adaptation risks, and overestimation and over-reliance on system capabilities. Further, user acceptability and strategic implementation issues are paramount to the successful introduction of these systems.

A Bibliometric Analysis of the Intelligent Transportation Systems Research Based on Science Mapping

“…To do that, techniques such as the driver's stress level detection [23], speed adaptation systems [24] and driver's behaviour control [25] were developed. This thematic area also covers topic such as the behaviour of drivers in traffic congestion [26].…”

Intelligent Transport Systems: The propensity for environmental and economic benefits

“…The crosssectoral efficacy of ITS would appear to be strong given that it can potentially contribute to significant improvements in road safety ( [83]; [84] and the economy ( [85], [86]). …”

Reliability prediction for the vehicles equipped with advanced driver assistance systems (ADAS) and passive safety systems (PSS)

“…ADA Saims at supporting drivers by either providing the warning to reduce risk exposure (e.g., driving over the speed limit, raising driver alertness (Spyropoulou et al, 2008)) or triggering control tasks which takes over the vehicle control to eliminate many of the driver errors leading to accidents (Piao &McDonald, 2008),to prevent DUI (Driving under Influence) (ICADTS, 2001;Mathijssen, 2005),and to assist in a better control of the vehicle (e.g., improving visibility of the road environment (Spyropoulou et al, 2008)). Now, technologies such as forward collision warning and avoidance systems, lane departure warning, side view assist, adaptive headlights, adaptive cruise control, and many more have become available in the market and many more are under development (Piao& McDonald, 2008;Jermakian, 2011).ADAS functions can be achieved through either an autonomous approach that includes on board intelligent vehicle systems, and wayside systems or cooperative approach which rely on interfaces between the vehicle and other vehicles on road and the road system components (Piao & McDonald, 2008).…”

“…The use of ADAS system may have several positive impacts such as mitigation of exposure to risky conditions, and improvement of driver behavior (e.g., reduced driving speed and speed variability, smaller lane deviations, faster reaction times, less harsh braking and enhanced alertness) (Spyropoulou et al, 2008) and eradication of driver errors (Stanton and Salmon, 2009). However, the potential negative effects include 1) drivers' shifted attention to road environment information that causes insufficient attention to the primary driving tasks, 2) inappropriate driver reactions (e.g.…”
