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.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.

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.
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 go through the process of identifying possible solutions to the design problems that the existing west corridor transit system faces. Students combine what they have learned from the three previous activities to come up with possible solutions to the design problems faced by the system.
Students are introduced to the concept of design criteria. Specifically, they determine what functionality the trains on the west corridor must meet to satisfy customer and owner needs. Students discuss what criteria need to be met and use the Mass Transit Living Lab—a web portal to interactive trai...
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.

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.

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.
