Civil Engineering

Attached is the paper instructions. In Project Statement: The writer is only required to do the following: Current Issues Inventory (10 points): - he describes the street and safety Design (40 points): Design and solutions and calculations to do Economic Analysis (25 points): Using the attached VISSIM data, he compares cost benefit. As for the Analysis (25 points) part, I have provided two attachments that have the date required for the analysis. (No need to create a VISSIM simulation CE 439: Traffic Engineering Operations Design Project Due: 12:00 pm November 16th, 2015 Directions: Your client, the City of Morgantown, would like you to analyze the University Avenue and Eighth Street intersection for possible improvements. They would like you to inventory the current intersection issues, and design, analyze, and assess economic costs and benefits of solutions. Note: speed limit=25 mph, design speed=30 mph, jam density=200 vpm Current Issues Inventory (10 points): Visit the study location to observe: • Categories of users and relative volumes • Geographic layout • Surrounding structures, landscape, etc. • Geometric features of intersection • Potential safety issues • Potential causes for congestion • Function and importance of intersection within larger network • Other concerns and unique aspects of intersection that should be Compile these observations in your report in a comprehensive manner with some discussion. Include any pictures or illustrations that you deem necessary. Design (40 points): Compile a list of possible alternative designs, solutions, or additive measures that can address some of the issues you found. In this list include a description of the proposed method including: • Design components • Current issues it will address and how • Benefits of design over other options • Negative aspects or potential issues • Example where this solution has been used in the past and how successful it was Each of these alternatives would require their own geometric and traffic design in real life but is not included in this project. For this project please study the provided intersection diagram for basic information on the current design. From the equations, regulations, and standards discussed in class, determine the: • Appropriate superelavation and transition lengths on each of the approach legs • Stopping sight distances for each approach • The distance objects ing the drivers view need to be placed away from the road • Proper use and placement of traffic control devices including: striping, pavement markings, regulatory signs, warning signs, and guide or marker signs • PC and PT of both horizontal curves and station of intersection • VPC, length of vertical curve, and station at intersection assuming grade on opposite side of crest would have equal grade • Capacity of each approach assuming Greenshields model • Identify whether or not there will be a dilemma zone if a signal were to be installed Analysis (25 points): Construct two simulations of the intersection using VISSIM. The first simulation should show the current configuration, and the second with a traffic signal. Compare the two scenarios using the travel time and delay data collection tools. Use the volumes and turning movements shown below in the figure for both simulations. Figure 1: Vehicle Demand Inputs and Turning Movements You can experiment and devise your own signal timing scheme. Choose whichever signal timing scheme you think is the best optimization for the intersection. Include in your report the phase diagram and signal timing for your signalized intersection. Discuss the results you receive from the VISSIM model. Mention any changes that can be made to improve the intersection model and if there were any errors or inconsistencies in the data explain why they may have occurred. Economic Analysis (25 points) Using the two simulations from VISSIM and their respective results, conduct a cost benefit analysis of the two alternatives. Conduct some basic research to find approximate unit costs or values for each of the categories. Some of the categories of costs and benefits to include but are not limited to: • Right of Way acquisition • Maintenance cost and lifespan of infrastructure • Construction materials cost • Construction labor cost • Time saved benefit • Crash reduction benefit • Benefit to pedestrians, cyclists, ADA, and surrounding businesses Additional Directions: Project submissions should be printed on 8 ½”x11” paper to be submitted in class on the due date, with proper explanations, citations, illustrations, graphs, and work shown for any calculations. Points will be deducted for work that is not of a professional quality. Please approach this project like it is an assignment from a client. The sections of the assignment are detailed below. Please identify the proper sections with headings in your report. Any data outputs from VISSIM or other additional information can be included in an appendix. Summary tables or figures and their respective analysis should be included in the report. Please email Colin Frosch [email protected] if you have any questions or concerns.
