 Traffic Flow Theory: Lab Exercises

 
Lab Exercise One: Flow Models

The attached data sets reflect field data taken at two sites in Huskytown. You are an engineering intern and you have been asked by your supervisor to analyze the data and prepare a brief report documenting any conclusions and recommendations that you have.

Using the "attached" data sets, analyze the data. Assume Greenshield's model for space mean speed as a function of density.

Attached MS Excel Data Set One
Attached MS Excel Data Set Two

Tasks to be Completed

Task 1: Using regression to determine the theoretical equation that describes the speed as a function of density:

  • Plot the actual data and theoretical data and describe any correlation.
  • Report all the important statistical results of the regression analysis.

Task 2: Using histograms, calculate and graph the following:

  • flow
  • speed
  • occupancy

Task 3: Using any analysis tools, plot:

  • flow versus occupancy
  • flow versus density
  • speed versus flow
  • speed versus density.

Task 4: Write up a report stating the information specified above, as well as your own conclusions about the data provided.
