The phrase "accident frequency" is correct and usable in written English.
It can be used in contexts related to safety, statistics, or risk assessment, particularly when discussing how often accidents occur within a specific timeframe or environment.
Example: "The company is implementing new safety measures to reduce accident frequency in the workplace."
Alternatives: "incident rate" or "accident occurrence".
Statistical analysis shows that accident frequency has an oscillatory behavior, rising in the last year.
This research statistically studies the effectiveness of ice warning signs in reducing accident frequency and accident severity in Washington State.
This approach is, therefore, appropriate to sites where the mean accident frequency exceeds a standard value for that site.
The prices for driving through certain zones, or at certain times of day, are "based in part on accident frequency and traffic density, and things we know to have occurred in that area," said Leslie Kolleda, a spokeswoman.
Stephen Jones, UK head of property and casualty pricing at Towers Watson, says the past three months of the year were driven by "falling fuel prices leading to increased driving [and] increasing accident frequency".
Statistical models, such as Poisson or negative binomial regression models, have been employed to analyze vehicle accident frequency for many years.
Despite the encouraging trend towards improved safety, accident frequencies remain high, many of which result in fatalities.
In a rationalist approach to safety, accident frequencies are quantified and protective measures are introduced to make these frequencies acceptably low.
The results of the two studies were analyzed statistically using Chi-square method to compare the actual to the expected accident frequencies.
For prediction of accident frequencies using fifteen input parameters, two modeling approaches: FENB/RENB regression and M5 model tree were used.
It seems unlikely that these ageing models can be relied upon to provide accurate and reliable predictions of accident frequencies on the roads today.
