OSRA 2022 Data Dashboard

Announcement!

BTS has released the second OSRA 22 statistics on chassis street dwell time and out of service rates. BTS is endeavoring to improve the granularity and usefulness of the statistics. We are pleased to announce that this release includes national statistics separated by chassis size and statistics for the Los Angeles market. The statistics include the average, median, and quartiles.

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 most individual markets that assure confidentiality. BTS will offer statistics by market when confidentiality can be assured.

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.
