The CS team agrees with the survey data presented above. However, surveys
may be biased since they were based on feedback from select CDOT employees.
While CDOT management and staff clearly recognize the need for governance
related to data collection and management, there is not a consistent
understanding regarding what is needed and how it would affect the
department. The following gaps were identified through stakeholder interviews
during this project.
No one office is championing data management or data governance (overall)
at CDOT.
There are varying definitions for terms – which results in misleading and
inconsistent data reporting, for example:
– The definition of “injury” has changed over time, and “crash rates” are
not calculated consistently (e.g., crashes per 100 million VMT and crashes
per million VMT are both used.)
– “Fatalities” and “fatal crashes” have been used interchangeably by
decision-makers though tracked separately.
– The term “lane miles” means at least four different things to four different
units across CDOT. It is also calculated differently – for example, some
units divide the number of lanes by twelve (assuming 12-foot lanes) and
others divide by fourteen.
Communication regarding data availability, sharing and sources is not
consistent.
