• Abstract:
  This report comprehensively reviews available traffic census technologies, focusing on assessing traditional methods—such as inductive loops, magnetometers, and infrared sensors—and advanced solutions, including video analytics, radar, and LiDAR. The study evaluates each technology's accuracy, cost-effectiveness, ease of implementation, and environmental resilience using a structured evaluation matrix. It also conducts a lifecycle cost analysis to clearly distinguish between traditional systems, known for their affordability and low maintenance needs, and modern technologies, which offer greater data precision and detailed analytics suitable for complex urban and multimodal traffic environments. Based on this thorough analysis, the report provides specific technology recommendations for deployment across various roadway environments, including freeways, arterials, and intersections. Additionally, it outlines best practices for effective training, maintenance protocols, and risk management to ensure sustained performance and reliability of traffic sensing technologies.
