Summary
Antilock braking (ABS) and other safety systems show potential to prevent many powered 2-wheeler (PTW) crashes. Combining ABS with other technologies can significantly improve rider safety and reduce the economic burden of PTW accidents.
Area of Science:
- Road safety engineering
- Transportation safety
- Motorcycle safety technologies
Background:
- Powered 2-wheelers (PTWs) are crucial for global mobility but pose higher injury risks than cars.
- Developing specific PTW safety systems is vital for reducing rider casualties.
- Evaluating the value of emerging active and passive safety technologies is essential.
Purpose of the Study:
- To prioritize active safety systems for PTWs based on their applicability to crash scenarios.
- To assess the potential impact of systems like antilock braking (ABS) and autonomous emergency braking (AEB) alone and in combination.
- To evaluate the societal economic cost of PTW crashes and potential reductions.
Main Methods:
- Assessed functional performance of 5 PTW safety systems: ABS, AEB, collision warning, curve warning, and curve assist.
- Rated system relevance to crash configurations using a standardized accident classification system by independent reviewers.
- Analyzed population-based crash data to determine potential crash influence and calculated economic costs and savings.
Main Results:
- Between 2000-2011, 23,955 PTW riders and 1,292 passengers were involved in crashes, with over 500 fatalities.
- The total economic cost of these crashes was estimated at AU$11.1 billion.
- The 5 safety systems were relevant to 57% of all crashes and 74% of fatal rider crashes; ABS showed relevance to the most crashes.
Conclusions:
- Antilock braking (ABS), individually and combined with other systems, can significantly mitigate or prevent a large proportion of PTW crashes.
- Other safety systems address different crash scenarios and are also recommended for PTW safety enhancement.
- The proposed prioritization approach can guide the selection of effective interventions to improve PTW safety, considering high crash costs and technology advancements.

233
Designing and plotting a curve using field data requires precise calculations and execution. A horizontal curve with a radius of 200 meters and an intersection angle of 20 degrees is established using the method of perpendicular offsets from the long chord. The long chord, which spans between the curve's endpoints, is calculated to be 69.46 meters in length. To maintain accuracy in plotting, intervals of 3 meters are selected along the chord.The engineer determines the offset distances for each...

Analysis of population pharmacokinetic data involves studying the behavior of drugs within diverse populations to understand their pharmacokinetic parameters. Traditional pharmacokinetic methods typically involve collecting samples from a few individuals and estimating these parameters. While these methods are commonly used, they have limitations in capturing the variability in drug response among individuals or heterogeneous populations. Population pharmacokinetics is employed to address these...

1.5K
The transfer function is a fundamental concept in the analysis and design of linear time-invariant (LTI) systems. It offers a concise way to understand how a system responds to different inputs in the frequency domain. It serves as a bridge between the time-domain differential equations that describe system dynamics and the frequency-domain representation that facilitates easier manipulation and analysis.

The limbic system, often called the "emotional brain," is a complex set of structures located deep within the brain. The intricate network of the limbic system supports a wide range of psychological functions, from emotional regulation to memory formation and sensory processing. This functional brain region encompasses specific parts of the diencephalon and the cerebrum, integrating the higher mental functions of the cerebral cortex with the primitive emotional responses of the deep brain...

Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...
