### Summary

Students are introduced to graphical analysis of data to analyze flaws in a transit system's design. They evaluate factors such as ride time, wait time and percentage of train capacity. This activity requires the use of the Mass Transit Living Lab—a web portal to interactive train (transit) traffic data for a major metropolitan city.
This engineering curriculum meets Next Generation Science Standards (NGSS).

### Engineering Connection

Transportation engineers are responsible for designing and operating the transit systems that deliver people and goods, including rail, highways and roads, and air traffic. Transportation engineers aim to design efficient systems that move people and goods quickly, safely and cost-effectively. Students become fully immersed in transportation engineering during this activity.

### Learning Objectives

After this activity, students should be able to:

• Plot simple variables versus time on graph paper.
• Calculate percentages and graph them versus time on graph paper.
• Answer questions quantitatively using information obtained from a graph.

### Educational Standards Each TeachEngineering lesson or activity is correlated to one or more K-12 science, technology, engineering or math (STEM) educational standards. All 100,000+ K-12 STEM standards covered in TeachEngineering are collected, maintained and packaged by the Achievement Standards Network (ASN), a project of D2L (www.achievementstandards.org). In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics; within type by subtype, then by grade, etc.

Students evaluate whether a particular section of a transit system is functioning in an efficient manner and whether it is meeting design requirements. Then, they suggest design improvements and evaluate whether the changes make positive impacts on the transit system performance.

High School Lesson
Mass Transit Living Lab: Analyze the Data

Students go through the logical process of quantitatively analyzing real-world transit data. They gain experience identifying problems with the current design based upon their earlier observations and experiences in activities 1 and 2.

### Introduction/Motivation

To better understand how a transit system evolves with time, engineers often graph different system parameters against the time of day that the system is in use. These graphs are helpful to quickly visually analyze design problems and investigate solutions. Graphs are also an important tool engineers use to present technical information to policy makers and the public in a manner that is informative to everyone.

### Procedure

1. Go to http://www.teachengineering.org/livinglabs/index.php > and click to enter the Mass Transit Living Lab to reach the main page of the Mass Transit Living Lab website (see Figure 1)
2. Distribute to students the Graphing the West Corridor Data Worksheet (for activity 2).
3. Present the Introduction/Motivation content to students.
4. Divide the class into teams of two students each, or have them work individually.
5. Direct students to work through the worksheet questions.

### Assessment

Grade the completed worksheets, reviewing student answers to gauge their mastery of the concepts.

### Other Related Information

This activity is designed around the Mass Transit Living Lab, a real-time simulation of FasTracks—a real, high-speed rail transit system in the Denver, CO, metropolitan area, as an example for analyzing data about how a light rail system works.
