abstract="The quantitative and qualitative separation of recurrent and non-recurrent congestion, and the contribution of different causes to freeway congestion, will enable the design of better correctional strategies. Typically, recurrent congestion is defined as &quot;the regular, everyday rush-hour delays that occur when the design capacity of a freeway is exceeded and low vehicular speeds result&quot; or, more technically, a &quot;condition lasting for 15 minutes or longer where travel demand exceeds freeway design capacity [and] vehicular speeds [decline] to 35 mph or less during peak commute periods on a typical incident-free weekday.&quot; Non-recurrent congestion is the extra delay caused by causes like weather, incidents, lane closures/work zones, and special events, among others.  <p>Language: en</p>",
