Traffic Data Collection

For three decades, DLZ has been contributing to the vast array of traffic data being utilized by public agencies from the local to federal level in the planning and analysis of our transportation networks. We utilize the latest in cutting edge technologies to collect accurate vehicular, bicycle, and pedestrian data in the most efficient and safe manners possible. Our full time field staff have a wide range of experience in collecting traffic data both manually and automatically utilizing modern equipment that has been tested and certified to provide the data that transportation agencies and consultants need to conduct the analysis, engineering and design of transportation systems. DLZ is adept at conducting the following:

  • Video and Manual Intersection/Roundabout Turning Movement Counts
  • Automatic Roadway Volume, Classification, Speed, Gap Studies
  • Pedestrian and Bicycle Counts on Street/Sidewalk or Multi-use Paths
  • Origin-Destination Studies
  • Travel Time Studies
  • Speed Studies
  • Parking Utilization Studies

Our staff has collected manual and machine volume and classification counts at intersection and expressway locations, parks, bike paths, parking lots, and toll way plazas for dozens of agencies, municipalities and corporations. We utilize state-of-the-art computer hardware and software for collecting and reporting data — Miovision cameras, Hi-Star magnetic portable traffic analyzers, Jamar hand-held count boards for manual counts, and Jamar and PicoCount counters for machine counts, with ample hardware to handle sizable counts at multiple locations. We have developed and processed databases for origin-destination survey information as well as for traffic counts collected by the firm, and we have in-house experience in Microsoft Access and GIS Applications, including the ESRI family of ArcGIS desktop, web and mobile apps.
