One ( 1 ) Statewide Agreement over a three ( 3 )- year term is needed for the purchase of traffic count data to include data collection , quality assurance / quality control ( QA / QC ), and vendor upload of accepted datasets into the State ’ s Traffic Data Management System ( TDMS ). Program scope and requirements include the following : • Program overview and quantity : o Approximately 1 , 000 accepted counts per year for three ( 3 ) years total ( approx . 3 , 000 accepted counts total ). o An accepted count is a dataset that passes QA / QC and all applicable TDMS business rules . • Count duration and reporting : o Each assigned count location is expected to include a minimum of 48 consecutive hours of continuous data collection . o Data shall be capable of being reported in 15 - minute intervals . • Acceptable count days : o Counts shall be collected on non - holiday weekdays , limited to Monday through Friday . o To ensure the full 48 - hour period occurs within a Monday - Friday window , the 48 - hour collection period shall begin on a Monday , Tuesday , or Wednesday , unless otherwise directed by the NHDOT . • Directional requirements : o Bidirectional data reporting ( both directions ) is anticipated for facilities with two ( 2 ) or more travel lanes within the counted cross section ( as applicable to the roadway configuration and assignment ). o Directional data reporting ( one direction ) is anticipated for single - lane facilities ( e . g ., one - way , single - lane roadways ). o If a different directional configuration is needed at a specific location , it will be identified by NHDOT in the assignment details . • Geographic coverage and location assignments : o Locations will be statewide , primarily on non - interstate and non - turnpike roadways . o “ Ramp ” means an entrance or exit roadway segment connecting surface streets to a limited access facility ( including interstates , turnpikes , and other limited access highways / expressways ). This definition is included to avoid confusion with “ ramp metering ,” which is a traffic control strategy . o NHDOT will provide geographic coordinates and assignment details in advance of each year ’ s work . o The distribution of non - ramp locations will be approximately proportional to population densities throughout the state .
