Interactive, field-ready computational utilities developed for civil engineers, municipal public works staff, traffic safety contractors, sign fabricators, and roadway inspectors conforming to FHWA MUTCD 11th Edition with Revision 1 (December 2025).
Interactive field selectors and purchasing guides for temporary traffic control hardware: cone height & spacing estimators, 36″ vs 48″ sign area comparisons, roll-up sign field specs, and ASTM D4956 retroreflectivity ratings.
Determine required sign blank dimensions, vertical mounting elevations, roadside lateral clearances, Table 2C-3 advance warning placement guidelines, and Table 2A-5 retroreflectivity standards.
Compute merging, shifting, shoulder, and one-lane two-way taper lengths, buffer stopping distances, channelizing device quantities, and verified Table 6H-1 sign packages under FHWA 11th Edition (Rev 1, Dec 2025).
Interactive field directory of all 54 FHWA Part 6 Typical Applications (Figures 6P-1 through 6P-54). Filter by roadway geometry, speed, work location, and closure activity to surface applicable typical applications and official source diagrams.
Calculate sign blank face area, stock sheet cutting yield, blade kerf gap losses, offcut scrap, and reflective sheeting order allowances for sign fabrication.
Estimate liquid paint volume in US gallons for roadway line striping, bicycle lanes, and parking stalls based on measured geometry and wet film thickness.
Comprehensive field selection guides for traffic cones, roll-up signs, portable stands, sign blank sizing comparisons, and retroreflective sheeting grades.
