Analysis of Single-Lane Roundabout Slip Lanes Using SIDRA

  title={Analysis of Single-Lane Roundabout Slip Lanes Using SIDRA},
  author={Majed Al-Ghandour and William J. Rasdorf and Billy M. Williams and Bastian Schroeder},
Roundabout intersections, increasingly used in the U.S., sometimes incorporate slip lanes to facilitate right-turning traffic flow and reduce delay, thereby increasing capacity and safety. Performance of a single-lane roundabout with an adjacent slip lane is modeled with the SIDRA Intersection analysis tool for three types of slip lane: free-flow, yield, and stop, and is compared to having no slip lane. The gap acceptance-based assessment considers four experimental traffic percentage…

A Decision Analysis Tool: Experimental Analysis of Roundabout Slip Lanes under Unbalanced Traffic Volumes

Results indicate that a free-flow slip lane exit type provides significant reductions in total roundabout average delay and the 95% queues and can be presented, and perhaps a more efficient way, as the best alternative using decision tree diagrams.

Experimental Analysis of Single-Lane Roundabout Slip Lanes: Fuel Consumption and Emissions

Vehicular fuel consumption and emissions performance (carbon dioxide (CO2) and carbon monoxide (CO)) are examined experimentally within single-lane roundabouts with slip lane under yield, stop, and

Exploring Pedestrian Scramble Options in a Single-Lane Roundabout:

This study evaluates impacts of incorporating pedestrian scramble crosswalks on pedestrian and vehicle delays within a roundabout and results indicate scramble affects the rate of pedestrian-vehicle conflicts and roundabout average delays.

Impact Analysis of Headway Distributions on Single-Lane Roundabout Entry Capacity

A modified model is proposed to adjust the HCM 2000 model to produce a model that produces smaller relative error and rootmean-square deviation than the model itself, and it is believe that the modified HCM2000 model outperforms the H CM 2000 model.

Simulation experiments of a two‐lane system show that the proposed FCA model is able to replicate decision‐making processes and estimate the effect on overall traffic performance.




It is found that the modern roundabout performed better than the existing intersection control (stop signs) in reducing vehicular emissions, thereby resulting in a positive impact on the environment.
