| Summary: | 59 subjects to determine if this system encouraged 65 mpb: 1) no lights, 2) steady-burn lights, 3) a flash rate of 17 flashes/min; no lights with a flash A prototype work zone interconnected flashing warning hics. causing confusion. The subjects' ranking of the five compared to a standard lane closure. The studies confusion and its likely effectiveness in encouraging earlier lane- changing upstream of a lane closure encourage subjects to leave the closed lane without flashes/min. Compared with the standard lane closure, flashes/min., and 5) no lights with a flash rate of 60 following treatments in conjunction with an arrow for Texas Department of Transportation (TxDOT). Prior lane-changing upstream of the lane closure. The lashes/min., 4) no lights with a flash rate of 17 light system was tested in this thesis research that motorists to leave a closed lane without causing of 60 flashes/min.; Steady-burn lights; No lights with panel were examined at two approach speeds, 30 mph and project by the Texas Transportation Institute (TT1) rate of 60 flashes/min; and no lights reactions of the subjects showed that the system did simulated a work zone with a left lane closure. The steady-burn lights with a flash rate of 60 the warning light system did not encourage earlier to full-scale field testing, proving ground studies treatments studied from the best treatment to the was conducted in coordination with an ongoing research were conducted at the TTI Proving Ground facility with worst treatment: Steady-burn lights with a flash rate |
