Announcement!
BTS is exploring avenues to provide statistics on chassis street dwell times and out of service by location without compromising the confidentiality of respondents to the data collection. Limitations of the current program do not enable statistics for individual ports that assure confidentiality.
This is an experimental data product. BTS experimental data may not meet all of our quality standards. We are seeking feedback from data users and stakeholders on the quality and usefulness of this new product.
About the Statistics
The statistics include the average, standard error, and percentiles. The standard error tells us how different the population average may be from the calculated average using the respondents’ data. The percentiles provide a distribution of the data and should be read as follows: For the 10th percentile, 10 percent of the data falls below [10th percentile value] and for the 25th percentile, 25 percent of the data falls below [25th percentile value] and so on.
