Abstract

The objective of this paper is to explore the effects of longitudinal speed reduction markings (LSRMs) on vehicle maneuvering and drivers' operation performance on interchange connectors with different radii. Empirical data were collected in a driving simulator. Indicators-relative speed change, standard deviation of acceleration, and gas/brake pedal power-were proposed to characterize driving behavior. Statistical results revealed that LSRMs could reduce vehicles' travel speed and limit drivers' willingness to increase speed in the entire connector. To probe the impacts of LSRMs, the connecter was split into four even sections. Effects of LSRMs on driving behavior were stronger in the second and the final sections of connectors. LSRMs also enhanced drivers' adaptability in the first three quarters of a connector when the radius was 50 m. Drivers' gas pedal operation would be impacted by LSRMs in the entire connector when the radius was 50 m. LSRMs could only make drivers press brake pedal more frequently in the second section with 80 m and 100 m radius. In the second quarter section of a connector-from the FQP (the first quartile point) to the MC (the middle point of curve)-LSRMs have better effects on influencing vehicle maneuvering and drivers' operation performance.
