As a student if traffic engineering/planning I'm a little confused about the use of OLS on count data. I'm currently reading Ortuzar and Willumson's book - Modelling Transport.
We've been assigned to build an OLS model with dependent/independent variables of our choice. In Ortuzar and Willumson's book, an OLS is discussed as one model to infer trip generation from geographical zones or households.
From my education, I find this problematic as the dependent variable is count data. I've read that OLS should have a truly continuous dependent variable (neg infinity to pos infinity). This cannot exist for number of trips per zone. The authors do discuss the use of a logit model, but im confused on why an OLS is included.
Is an OLS correct to use in calculating trip generation? Is there some law I'm missing?
Im interested in cycling and therefore would like to model bike trip generation. My plan was to build a model with origin destination cycling (strava) data by assigning number of commute trips from zones as dependent variable, and income, population density, land value as independent variables.
Any guidance on building an OLS to understand the first step in a 4 step model, trip generation would be highly appreciated.
