Experimental Analysis of Single-Lane Roundabout Slip Lanes: Fuel Consumption and Emissions
Vehicular fuel consumption and emissions performance (CO2 and CO) are examined experimentally within single-lane roundabouts with a slip lane under yield, stop, and free-flow exit control scenarios; these are compared with no slip lane using a gap acceptance-based performance experimental assessment SIDRA tool. For comparison with other types of traffic control, the same experimental roundabout is converted into a signal intersection and into an all-way stop-controlled intersection. With a free-flow slip lane exit type, overall average total roundabout fuel consumption was reduced by 26%, CO2 emissions were reduced 27%, and CO emissions were reduced 17%, compared with an all-way stop-controlled intersection. As expected, results indicate that a roundabout with a free-flow slip lane exit type significantly reduces total average fuel consumption and pollutant emissions within a roundabout compared with all-way stop-controlled intersection.
