Question Description

See the attach files You will study the site from the maps on the Google Earth website I already did it this part and study the site in terms of car density and crowding and what stores we have in these locations and traffic movement in the site and compare the measurements that have been added on the Word file for each site. and use the PowerPoint file and the reference as well.

Word File : Question and I add some info to help you to work on it to complete what I did.

Powerpoint File : Slide and instructions.

pdf file: Refrence

Thanks

Alternative Intersections: Median U-Turns Q: The Design Alternatives portion involves analyzing the similarities and differences between several different constructed Median U-Turn locations with respect to geometric and area characteristics. (See MUT lecture and MUT Informational Guide for guidance as to what should be included/discussed. Tables, images/figures, and related commentary would work well for this task.) The sites to be considered come from page 120 of the MUT Informational Guide PDF document (numbered page 112 of the document). Consider the 1st 4 locations, which include: o o o o US 280 at Valleydale Road, Birmingham, AL West Ina at Oracle Rd, Tucson, AL W Grant Rd at N Oracle Rd, Tucson, AL 96th at Allisonville Rd, Fishers, IN Coordinates are given within the Guide that can be used to set pins within Google Earth. And explain the area and what is exactly on the area include for place and property and what the car and truck use this kind of this Median U-Turns also how are the Geometric Design → Design Approach and Geometric Design → Parameters/Principles and Design Guidance for all. Do it for all 4 interstation. Here some work I did and so you can understand what I need and see it and continue work it and all also see the reference I submit it and force on the slide file and pdf as well.

In 2012, FHWA chose Intersection & Interchange Geometrics (IIG) to feature as one of the innovative technologies in EDC-2. Specifically, IIG consists of a family of alternative intersection designs that improve intersection safety while also reducing delay, and at lower cost and with fewer impacts than comparable traditional solutions. As part of the effort to mainstream these intersections, FHWA has produced a series of guides to help transportation professionals routinely consider and implement these designs. Concurrent with this Median U-turn (MUT) Informational Guide, FHWA developed and published guides for three other designs: Restricted Crossing U-turn (RCUT), Displaced Left Turn (DLT), and Diverging Diamond Interchange (DDI). These guides represent summaries of the current state of knowledge and practice, and are intended to inform project planning, scoping, design and implementation decisions.

Abstract This document provides information and guidance on Median U-Turn (MUT) intersections, resulting in designs suitable for a variety of typical conditions commonly found in the United States. To the extent possible, the guide provides information on the wide array of potential users as it relates to the intersection form. This guide provides general information, planning techniques, evaluation procedures for assessing safety and operational performance, design guidelines, and principles to be considered for selecting and designing MUT intersections. 17.
