Statistical Test for 85th and 15th Percentile Speeds with Asymptotic Distribution of Sample Quantiles
The 85th and the 15th percentiles are two parameters that are commonly used in traffic engineering and traffic safety. For example, 85th percentile speeds are used in setting speed limits and for … [Read more...] about Statistical Test for 85th and 15th Percentile Speeds with Asymptotic Distribution of Sample Quantiles
Optimal Work Zone Lengths and Signal Timing for Two-Lane Highways Revisited: The Need to Consider Stochasticity
Work zones can give rise to significant costs, both to maintenance agencies as well as to road users. In this paper we focus on the optimal configuration of work zones on two-lane highways. While … [Read more...] about Optimal Work Zone Lengths and Signal Timing for Two-Lane Highways Revisited: The Need to Consider Stochasticity
