Traffic Counts

The Traffic Counting Program is an integral part of the Transportation System Surveillance. BHJ forsees traffic counting as the foundation of a performance measurement-based planning program consistent with MAP-21 planning requirements. This program provides a sound and factual basis to support ongoing transportation planning work. Annually, between March and October, BHJ collects traffic count information from approximately 375 individual traffic counters throughout the region. Traffic counting is valuable for Travel Demand Model development, highway performance monitoring including pavement condition ratings, identification of probable economic growth patterns, safety-engineering studies, and other miscellaneous transportation planning activities.

Each year, BHJ compiles a Traffic Count Program Report that typically details each year’s traffic counting activity and the data collected at the traffic count locations throughout the tri-county study area. Almost half of all traffic counts BHJ collects are for Short-Range Planning activities, typically highway performance monitoring on local roads, streets, and highways where neither ODOT nor WVDOT have administrative responsibility. In continuing, more than 35% of the remaining traffic data is collected for Long-Range Planning efforts for the Travel Demand Modeling program at either a screen or a cordon line location, while the Surveillance Program accounts for the rest of the counting program.
