Snow & Ice Removal CSF

Percent of Ohio’s primary and secondary roads that return to within 10 mph of expected speeds after the end of a snow event. Percent based on 2 hours for primary routes and 4 hour for secondary routes.


ODOT Road Weather Information System (RWIS) stations detect weather conditions statewide. ITS speed data is collected and provided to ODOT 24/7 across all maintenance priority routes. A weather event begins when a percentage of the RWIS stations in a county detect snow or ice AND a percentage of maintenance priority routes in the county have a speed drop. The weather event ends when it stops snowing and winds have died down (to account for drifting). When the weather event ends, the county maintenance crews are “on the clock.” This metric reports the number of priority routes not reaching expected speeds within two hours after a snow event.


GA for each bridge is measured on a scale from 0 (closed) to 9 (new). All inspected bridges in the country use this scale and system. Since bridges vary in size, it would not be a true representation of Ohio’s bridge conditions to average together a single score per bridge without figuring in the bridge’s size. The agency calculates a weighted average GA for all bridges by factoring in the total area for each bridge along with its GA, with the target being above the stated goal. ODOT currently maintains approximately 13,898 bridges statewide. 


The Snow & Ice Control metric is reported and published monthly in the CSF Dashboard during the winter weather season (typically from November through March).


Maintenance priority routes are determined at a county level and the reporting is done statewide for the identified routes.


The Office of Traffic in Central Office is responsible for calculating and reporting the Snow & Ice Performance Evaluator.
