10/30/2022 0 Comments Alternative DesignsThe team has completed the preliminary design alternatives. Three total transportation redesigns were created, each with its own benefits and drawbacks. In the design process, a different perspective was used for all three iterations. The redesigns' main priority is safety. In some designs, the flow of traffic was held in higher regard than in the other designs, in which pedestrians' safety was prioritized to a degree that the flow of traffic was subsequently sacrificed. Both sidewalks and bike lanes are included in all three redesigns, although they are not visible in the drawings. Sidewalks and bike lanes are a priority in the overall redesign to improve and implement more connectivity within the residential areas and local businesses Alternative 1: RoundaboutsThe first alternative design for the intersections consists of utilizing a roundabout at both HWY US-9 and Halls Mill Road, as well as at Adelphia Road, as shown in Figure 1.4 and Figure 1.5. The emphasis of this intersection is to create a safer environment without sacrificing the rate at which traffic will flow. Figure 1.5 shows the Halls Mill Road and Adelphia Road intersection, and Halls Mill Road was also realigned to provide a safer curve and allow the road to intersect into the roundabout. Islands are going to be designed for pedestrians and bicyclists at the intersection of HWY US-9 and Adelphia Road. The islands will allow for a safer crossing while also allowing traffic flow to continue unimpeded. Alternative 2: Roundabout & Square IntersectionFigure 2.1 and Figure 2.2 represent the second alternative redesign. Figure 2.1 shows a square intersection designed for HWY US-9 to control traffic flow and implement sidewalks and bike lanes for local pedestrians who want to travel to nearby stores. Figure 2.2 displays a roundabout with an island replacing the existing design that does not have pedestrian access. The main goal of the second design was to create intersections that slow down traffic on HWY US-9 and allow safer pedestrian and bike travel along these roads. The Halls Mill Road intersection would prevent traffic congestion buildups. Both Figure 2.1 and 2.2 prioritize slower travel for vehicles. |
