QUANTITATIVE SAFETY ASSESSMENT OF AIR TRAFFIC CONTROL SYSTEMS THROUGH SYSTEM CONTROL CAPACITY
Quantitative Safety Assessments (QSA) are essential to safety benefit verification and regulations of developmental changes in safety critical systems like the Air Traffic Control (ATC) systems. Effectiveness of the assessments is particularly desirable today in the safe implementations of …

Pedal Misapplication: Past, Present, and Future
… simulation and evaluate the overall potential safety benefit of a theoretical PM advanced driver assistance system. Using an established keyword search identification method and two unique crash datasets, a PM crash frequency of approximately 0.2% of all crashes was found. These PM crashes were …

MULTI-UNIT ACCIDENT CONTRIBUTIONS TO U.S. NUCLEAR REGULATORY COMMISSION QUANTITATIVE HEALTH OBJECTIVES: A SAFETY GOAL POLICY ANALYSIS USING MODELS FROM STATE-OF-THE-ART REACTOR CONSEQUENCE ANALYSES
… U.S. Nuclear Regulatory Commission implemented a safety goal policy in response to the 1979 Three Mile Island accident. This policy addresses the question “How safe is safe enough?” by specifying quantitative health objectives (QHOs) for comparison with results from nuclear power plant (NPP) …

Evaluating Ramp Metering And Variable Speed Limits To Reduce Crash Potential On Congested Freeways Using Micro-simulation
… have the potential to be used as real-time safety measures on freeways. They may also act as the basis for the evaluation of several intervention strategies that might help in the mitigation of risk of crashes. Ramp Metering and Variable Speed Limits are two approaches which have the …

Demonstrating an Equivalent Level of Safety for sUAS in Shielded Environments
… detect and avoid standards require the same safety metrics, even when in close proximity to the ground or structures. This requirement has the potential to hinder low altitude small unmanned aircraft operations, such as local package delivery and utility inspection. One of the main safety …

Performance evaluation of evasion maneuvers for parallel approach collision avoidance
… (SOC) curves were used to assess the benefit of alerting with each maneuver. This analysis shows the climb-only maneuver to be a poor substitute for the turnclimb. For a 2500 ft runway spacing and an expected 2 sec pilot reaction time, and with the nominal alerting threshold settings …

Scenario-Based Methodology for Predicting the Safety Benefits of Emerging Advanced Rider Assistance Systems (ARAS)
… Despite decades of progress in automotive safety, motorcyclists continue to experience disproportionately high rates of serious and fatal injuries. The combination of inherent vulnerability, limited physical protection, and exposure to complex traffic environments led the motorcycle …

A bi-level system dynamics modeling framework to evaluate costs and benefits of implementing Controller Pilot Data Link Communications and Decision Support Tools in a non-integrated and integrated scenario
A modeling framework to evaluate the costs and benefits of implementation of Controller Pilot Data Link Communication (CPDLC), and Air Traffic Management (ATM) decision support tools is proposed in this paper. The benefit/cost evaluation is carried out for four key alternatives namely alternative …
