# Hands-on Activity:Mass Transit Living Lab: Analyze the Data

### Summary

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. Students discuss the flaws that they find in the system. This activity requires the use of the Mass Transit Living Lab—a web portal to interactive train 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:

• Analyze a graph for critical areas and be able to explain in words what is happening in the graph.
• Critically examine a flow rate system for congestion and identify whether or not the system is meeting the original design criteria.

### 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.

###### NGSS: Next Generation Science Standards - Science

This standard focuses on the following Three Dimensional Learning aspects of NGSS:
Science & Engineering Practices Disciplinary Core Ideas Crosscutting Concepts
Design a solution to a complex real-world problem, based on scientific knowledge, student-generated sources of evidence, prioritized criteria, and tradeoff considerations.Criteria may need to be broken down into simpler ones that can be approached systematically, and decisions about the priority of certain criteria over others (trade-offs) may be needed.

### Materials List

Students each need a worksheet and pencil.

Teams each need a computer with Internet access to the following webpage: http://www.teachengineering.org/livinglabs/fastracks/.

### Introduction/Motivation

An essential part of an engineer's skill set is to be able to systematically analyze a design or system that is already in place and identify any areas that need improvement.

The first step to solving an engineering challenge is to identify it and the factors that are contributing to it. Only after the problem has been fully understood can an engineer effectively move toward finding solutions to the problem.

### 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 Analyze the Data Worksheet (for activity 3).
3. Present the Introduction/Motivation content to students.
4. Divide the class into teams of two students each, or have them work individually.
5. Ask students to work through the worksheet questions.
6. As a class, discuss the answers developed by individual groups.

### Assessment

Grade the completed worksheets, reviewing student answers to gauge their comprehension 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.
