- Helicopter Hover Ceiling (Multiple Regression) This is an actual engineering project done for Montana's Department of State Lands. Data from paper charts is used to develop formulas to calculate allowable helicopter payloads. The data involve multiple input variables and therefore the statistics activity includes multiple regression calculations using Excel.
- Speed Studies (Single Variable Descriptive Statistics) The procedure for conducting speed studies on a roadway is explained. Two examples are then given. One of the examples uses actual traffic count data from a speed study conducted on North Montana Avenue. Statistics activities include calculating and interpreting single variable statistics from raw and summary data and constructing cumulative frequency histograms and polygons using Excel.
- Poisson Distribution and Traffic Applications Several transportation applications using the Poisson and negative geometric distributions are presented. Activities include the probable number of vehicles arriving at an intersection over a given time period and the distribution of gap times between vehicles in a traffic stream.
- Traffic Flow Theory (Linear Regression) These materials includes a brief discussion of traffic flow theory. Two examples are then given, one involving raw traffic data and the other using results from two speed studies conducted on a stretch of North Montana Avenue. Statistics activities include linear regression calculations and graphing using Excel.
