What’s on the Traffic Surveys poster
A 6-row table: Measure · What it means.
Counts are cheap. Interpreting them badly is not.
- AADT — Average daily flow across a year
- Peak hour flow — The hour the design must serve
- Design hour volume — Often the 30th busiest hour
- Directional split — Share going the busier way
- Classified count — Mix of cars, buses and lorries
- Turning count — Movements through a junction
Educational reference. Short counts are scaled to annual values by seasonal factors, and that scaling carries real error.

- Who is the Traffic Surveys poster for?
- Traffic Surveys belongs to the Civil Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning transportation can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Traffic Surveys poster?
- Specifying a count, or reading someone else's traffic data. A wall chart earns its place by being glanceable from where the work is happening, so Traffic Surveys belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.
- What other posters go with Traffic Surveys?
- CBR & Subgrade, Road Cross Section and Mass Haul sit alongside Traffic Surveys in the Civil Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.CBR & SubgradeRoad Cross SectionMass Haul
- Is the Traffic Surveys poster free to download and print?
- Yes. Traffic Surveys downloads as a free PDF with no account, no email and no watermark, like everything else in the Civil Engineering section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Traffic Surveys poster print at?
- Traffic Surveys is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Traffic Surveys loses nothing.Printing guide
