Road safety risk evaluation and target setting using data envelopment analysis and its extensions

Road Safety Risk Assessment: An Analysis of Transport Policy and Management for Low-, Middle-, and High-Income Asian Countries

“…The process of producing a composite value of the risk mean value was undertaken to evaluate the risk, but DEA provides an opportunity to combine multiple variables. This is because DEA is a technique that maintains a mechanism of multiple inputs and multiple outputs for the evaluation of risk [20]. A conceptual diagram of the DEA model is shown in Figure 2.…”

“…As given in [20], its mathematical expression is as follows. Previously, risk evaluation was based on different parameters like public risk and traffic risk.…”

“…A conceptual diagram of the DEA model is shown in Figure 2. It is a linear programming technique for measuring the relative performance of entities multiple inputs and multiple outputs for the evaluation of risk [20]. A conceptual diagram of the DEA model is shown in Figure 2.…”

Incorporating Workplace Injury to Measure the Safety Performance of Industrial Sectors in Taiwan

“…Thus, workplace injuries are unwelcome byproducts of economic activity [12,22]. Researchers have begun to consider workplace injury rates as unwelcome (undesirable) outputs in assessing the safety performance of business operations in a single sector or industry (e.g., [11][12][13][14]). This paper assumes that the three workplace injury rates are undesirable outputs.…”

“…El-Mashaleh et al [12] incorporated five types of work accidents into the output-oriented CCR model to evaluate the safety performance of construction contractors. Shen et al [13] used the output-oriented CCR model to evaluate road safety performance in countries and considered mortality rate as an output. Finally, Egilmez and McAvoy [14] incorporated fatality rates into the output-oriented Malmquist productivity…”
