Emissions	Emissions levels for Volatile Organic Carbons VOC, Oxides of Nitrogen NOx and Carbon Monoxide CO continue to increase over today's levels with increases in traffic and congestion.	9.4% reduction in VOC 3.9% reduction in NOx 5.7% reduction in CO (daily emissions basis)	24.9% reduction in VOC 11.4% reduction in NOx 5.7% reduction in CO (daily emissions basis)
Safety	36 conflict points Potential for 'T-bone' crash, a more severe type of automobile crash than 'Sideswipes'.	36 conflict points Potential for 'T-bone' crash, a more severe automobile crash type than 'Sideswipes'.	Automobile crashes are far less likely to be T-bone and more likely to be sideswipes, a less severe type of crash. This is likely to reduce injury and death due to vehicle crashes. Superstreet reduces the number of conflict points, reducing conflict points to eight, including four merging and four diverging conflict points. By eliminating the crossing conflict points that have the potential for the highest crash rate and injury rate, the overall crash rate and serverity are reduced.
Bike/Ped	No bicycle facilities. No pedestrian signals or crossings. Crossing of US 15-501: Pedestrians and bicyclists must cross three sets of lanes.	No bicycle facilities. No pedestrian signals or crossings. Crossing of US 15-501: Pedestrians and bicyclists must cross three sets of lanes with the addition of one more turn lane.	Crossing facilities are installed. Pedestrians and bicyclists cross one set of lanes on US 15-501 at a marked and signalized crossing, follow a multi-use path through the center the median and cross another set of lanes at a marked and signalized crossing. This improves safety for bicyclists and pedestrians when crossing.
