Summary

This is a 10-year traffic count data comparison spreadsheet maintained by the Maine Department of Transportation (MaineDOT) documenting Annual Average Daily Traffic (AADT) volumes at 130+ Continuous Count Sites (CCSs) across Maine from 2013 through 2022. The dataset tracks bidirectional traffic volumes at fixed monitoring stations located on state routes, U.S. highways, and interstate corridors throughout Maine, capturing traffic patterns at critical locations such as I-295 near Portland, I-95 at Kittery and various points north, and key state routes including SR 11, SR 27, and US 1. The data enables year-over-year traffic trend analysis and supports transportation planning, capacity assessment, and infrastructure investment decisions. Each monitoring location includes station identification numbers, directional breakdowns (northbound/southbound, eastbound/westbound), and percentage change calculations between 2020 and 2021 to identify traffic recovery following pandemic-related disruptions. The spreadsheet reveals mixed traffic patterns across Maine's network, with some locations experiencing modest growth (such as Kittery I-95 northbound at 8.2% increase) while others show modest declines, with particular reductions evident at remote locations like East Machias SR 191 (-13.1%) and Mattawamkeag US 2 (-11.1%).

This dataset directly supports MaineDOT's Traffic Count Software as a Service (SaaS) procurement (RFP #202510141), which seeks a cloud-based platform to manage approximately 5,000-7,000 annual portable short duration counts and 130+ continuous count sites with full data collection, processing, quality control, and reporting capabilities. The historical traffic count data contained in this spreadsheet represents the type of information that must be converted and integrated into the new SaaS system, with requirements to preserve up to ten years of historical data. The new contract will commence January 10, 2026, with an initial three-year performance period through March 9, 2029, and includes two optional three-year renewal periods extending potential contract duration through March 9, 2035. Proposals are due December 3, 2025, at 11:59 p.m., with evaluation on a 100-point scale emphasizing organizational qualifications (20 points), proposed services and technical capabilities (50 points), and cost (30 points). The contract will be federally funded under Federal Funding Contract Rider D, and the incumbent service provider is Drakewell Inc.
