2 Event Description The City of Irvine has plans to develop single family homes on a vacant property in Planning Area 1 (PA1). The location of PA1 in the City of Irvine is identified at the end of this document for reference. The proposed project at PA1 is the development of 95 single family homes. A proposed site plan of PA1 is provided at the end of this document for reference. The location is viewable on Google Maps in this link: A topographical map of PA1 can be downloaded here: Objective The objective of this competition is to conduct a traffic analysis (trip generation, trip distribution, and intersection analysis) of the proposed project and design a site access intersection that accommodates multiple modes of transportation efficiently, safely, and economically. Participant Rules There is no limit to how many people can participate in this event, but at least one person must be present during the Poster Session to answer questions. Competition Requirements Trip Generation/Trip Distribution Analysis A trip generation analysis should be conducted for the proposed project. A figure detailing trip distribution assumptions for the proposed project at the intersection should be prepared. Trip distribution assumptions should account for locations of employment and commercial centers to which residents of the project would be drawn. All calculations must be presented with appropriate references to the manuals used. Intersection Level of Service Analysis An AM and PM peak hour intersection Level of Service (LOS) analysis should be conducted for the proposed intersection. The analysis should be conducted using the Highway Capacity Manual method. The calculations can be done by hand or using an intersection analysis software (Synchro, HCS, Vistro, Traffix, etc.). All calculations or software output sheets must be presented with appropriate references to the manuals used..

3 The following information should to be used for the analysis of intersection. Build Out Year: 2020 Traffic Growth Rate: 1% annually Existing (2016) Traffic Volume: Duration Direction Volume Daily AM Peak Hour PM Peak Hour Eastbound Westbound Eastbound 2272 Westbound 948 Eastbound 1097 Westbound 2654 Intersection Design The intersection design will focus on the plan view design intersection. A vertical design is not required as part of the design submittal. The design should encompass the extent of the intersection elements (intersection, turn-pockets, tapers, transitions, etc). The design should incorporate accommodations for all modes of transportation. The plan view should indicate the centerline, edge line, medians, shoulders, sidewalks, bike lanes, bike paths, and any other part of the roadway, including striping and signage. All equations used for the intersection design must be presented with each variable defined. At least one sample calculation must be shown for each equation used and the manual from which the formulas are referenced must be cited. Cost Estimates Separate cost estimate tables for the construction and the maintenance of the proposed intersection should be developed. Tables should be detailed and include unit cost and total cost for each item, as well as 10% mobilization cost and 15% contingency. The maintenance cost estimation table should show maintenance costs assuming that maintenance would occur every 2 years for a total of 20 years. Cost estimate references should be cited.

4 Written Report All submissions mentioned above will be compiled in a written report and will be formatted in this order: Cover Page o Include school name and names of all contributing members. Table of Contents List of Figures & Tables Introduction o A description of the project, design constraints, and parameters Trip Generation/Trip Distribution Analysis o An explanation of how trip generation analysis was conducted and the results o Table presenting the calculations o Figure presenting trip distribution assumptions Intersection Level of Service Analysis o An explanation of how the intersection Level of Service analysis was conducted and the results Intersection Design o Description of the proposed design o Discussion of the design decisions made and why they are appropriate o Discussion regarding how the proposed intersection affects the various modes of transportation Cost Estimates o An explanation of how the cost estimates were conducted and the results Summary o Provide an overview of the report o Identify what sets design apart o Identify how the site plan could be changed to improve site access and internal circulation References Tables o Trip generation table o Level of Service results table

5 o Cost estimate tables Figures/Plans o Trip distribution assumptions figure o Intersection design plans Technical Appendices o Trip generation calculations o Intersection Level of Service calculations o Intersection design sample calculations The main part of this report (Introduction to Summary) should not exceed 12 pages. The Cover Page, Table of Contents, List of Figures & Tables, References, Tables, Figures/Plans, and Technical Appendices are not included in this page count. Plans should be shown on an 11 x 17 inch page. All bids should be submitted to asce.uci.conference@gmail.com by March 4. The subject of the should be Transportation Bid [School Name]. Poster Session All schools should prepare a poster summarizing their design for Saturday, April 8 th, 9:00-11:00AM. At least one person who contributed to the bid should be present during the poster session to answer any questions the judges may have. Individual member names do not need to be included on the poster. Each poster should include at least the following: School name Trip generation table Trip distribution assumption figure Intersection Level of Service results table Plans of the designed intersection Cost estimates
