Permanent traffic recorder installation

Permanent traffic recorders have the capability to continuously collect volume, classification, speed and weight data on just about any traveled roadway throughout the year. A traffic counter can be configured to collect one to all of these data elements.

Telemetry installation

The installation of telemetry equipment for data retrieval includes the following data format types:

  • Raw data: This format will include lane number, time stamp, speed, number of axles, length and axle spacing for each vehicle. Depending on the telemetry equipment used, this type of data could take longer to download as it requires more storage space.

Traffic control

Work zone traffic control is provided for single or multiple lane closures on state highways, county roads, city streets, tribal and natural resource areas according to WSDOT M54-44 guidelines. Flagging operations are also available at various two-lane roadways. All field personnel carry a current flagger’s card and several carry a traffic control supervisor card.

Traction tires are a special type of tire

manufactured with at least 1/8 of an inch tread. Traction tires are usually marked with a mountain/snowflake symbol, the letters M+S or “All Season.”

Carry chains, practice before leaving

Requiring chains keeps traffic moving during storms rather than closing a pass or roadway.

Prep your car. Fill up your gas tank,

pack jumper cables, ice scraper, warm clothing, snacks and water.
