In order to be able to structure the most effective plan for a specific worksite, it is necessary to understand the factors that determine commuter response to company incentives to change commuting habits. This study compares the predictive ability of neural networks compared to linear regression models in calculating the change in vehicle trip rate (VTR) at a given worksite over a year long travel plan period. Using a Los Angeles area dataset (n = 3439), linear regression and neural network models were constructed and optimized using input variables including worksite incentives, business type and number of years of incentives at the worksite. Significant differences(p=0.006, 0.007) in program effectiveness were discovered between the results of local authority worksites ([delta]VTR = -1.495) and both businesses ([delta]VTR = -0.986) and hospitals ([delta]VTR = -0.728). It was determined that the neural network (R² = 0.229) performed better than the linear regression models (R² = 0.038) when evaluated by R², representing an improvement of 0.014 on previous models.","abstract_html":"Commute trip reduction plans are being implemented at an increasing number of worksites.
