4/2/2008 1 Waiting for the Worms 12-100 Introduction to Civil and Environmental Engineering Spring 2008 Project 3. “Waiting for the Worms” Schedule Project distributed April 2 Group work April 7, 9 Data sheet submission April 21, 5:00 PM Signal Setting Comparison April 23 Presentation of oral report April 30 Submission of written reports May 2, 5:00 PM Project Assignment In this project, you will analyze possible changes and make recommendations for three intersections and traffic signals along Wilkins Avenue in Squirrel Hill. These are a short walk up Beeler St. to Wilkins Avenue, or you can take a 67 Route PAT bus. You should use the methodologies and equations in the handout ‘Traffic Signal Setting’ to aid you. In doing this project, you need to schedule time for data gathering well in advance of analysis and report writing (and hopefully on days with nice weather). Also, be careful with consistency of units! Your project and report will consist of five major parts: 1. Existing Traffic Volumes, Delays, and Signal Setting You will gather data on traffic volumes and average delays during the evening (PM) peak at three different intersections: Wilkins and Wightman, Wilkins and Negley, and Wilkins and Shady. Your data gathering should include: a. Vehicle queues and volumes by lane for each approach. A methodology for gathering data and estimating delays is included in the traffic signal setting handout. At a minimum, your data gathering will include two 15 minute observation intervals for each intersection approach (see Figure 1) during the period 3:30 pm to 4:30 pm, with the two observation periods on two different weekdays. b. Estimate the average number of passengers in automobiles and buses based upon a sample of at least 30 automobiles and 4 buses. This estimate is only needed for the entire study area, not each intersection individually. c. Measure the volume of pedestrian traffic at each intersection. d.
