Time/distance to make a lane change? Passing Manuever?

Post by brian »

Q: What is the approximate time/distance for a vehicle to make a lane change?
A: As a part of a FHWA curve study we investigated cross slope design and in particular the effect of cross slope design on passing maneuvers for vehicles and trucks:
"HVOSM Studies of Highway Centerline Crowns", Contract DOT-FH-11-9575, October 1983 J.C. Glennon, T.R. Neuman, B.G. McHenry.
At the time of the research the only research found that directly measured the passing path of vehicles under normal highway operations was in the following:
  • "Frictional Requirements for High speed passing maneuvers”, Glennon, Texas Transportation Institute Research report No 134-7, July 1971 and
    Passing performance Measurements related to Sight Distance design”,Weaver & Glennon, Texas Transportation Institute report 134-6,, June 1971
Here are a couple more recent studies which may include additional information: Figures from Centerline Crown Study:
