About this file
This is a traffic count data analysis document prepared by the Maine Department of Transportation (MaineDOT) Traffic Engineering Division-Traffic Monitoring Section, presenting 2014 weekly traffic volume factors as a percentage of Average Annual Daily Traffic (AADT) for the period of 2011-2013. The document provides 52 weeks of data organized by month, with traffic factors calculated for three distinct road classifications: Urban Arterial (Group I), Recreational (Group II), and a third classification (Group III). The data is further segmented into combined group factors (I + II, II + III, and I + III) to enable comprehensive traffic pattern analysis across different road types and seasonal variations. The factors range from 0.64 to 1.56 as a percentage of AADT, with notable seasonal trends showing lower traffic volumes during winter months (December through February, with factors as low as 0.64-0.65) and elevated volumes during summer months (June through August, with factors reaching as high as 1.56).
The data illustrates pronounced seasonal fluctuations in traffic patterns, with recreational areas experiencing the most dramatic variation between seasons, reaching peak factors of 1.49-1.56 during July and August when recreational activity is highest, and dropping to 0.64-0.72 during winter months. Urban arterials maintain relatively stable factors year-round, ranging from 0.88 to 1.16, indicating more consistent traffic demand regardless of season. This historical traffic factor data serves as a critical resource for the MaineDOT's Traffic Count Software as a Service (SaaS) procurement, which requires the selected vendor to manage and process traffic data from approximately 5,000-7,000 annual portable short-duration counts and 130+ continuous count sites, with the ability to generate federal reporting submissions including HPMS and TMAS data.
