The author calls into question for the current practice of treating the Freight Generation (FG) andFreight Trip Generation (FTG) as same concept. Freight Trip Generation clearly varies from theconcept of Freight generation as the former is mainly based on the logistic designs and the latteris depending upon the production and consumption capacity. With the increase in the FreightGeneration or the consumption, doesn’t necessarily increase the trips as with the increase in theproduction/consumption the mode or the logistic decision may vary and may lead a situation withmore or even less number of trip generation as the transportation cost comes in act. Thus implyingthe use of constant FTG rates could be overestimated or underestimated depending on the businessand the freight involved.EOQ model has been proposed to minimize the logistic cost by considering the shipment size andthe frequency of delivery which clearly shows the difference between FG and FTG. Consideringthe economics perspective two separate aspects of land use and FTG has been considered, one landuse at establishment level and the other how the freight activity and land use interact with eachother at the system level. “The Author used simple Linear modeling process based on employmentas the sole independent variable, freight production (truck trips made per day) and freight attraction(deliveries received per day) were the dependent variables”, to analyse FTG rate on the businesssize versus the constant FTG rates by considering dataset of 400 Carriers and 400 receivers in theNew York City area and they were grouped into eight sectors resulting into three cases. “Threecases are, Use of constant FTG rates per employee, both intercept with coefficient of employment& only the intercept as significant and not depending on business size.The results show that for majority of cases (52%) FTG rate is constant, only 18% of the industrysectors exhibit a constant FTG rate per employee and the remaining 30% exhibit a constant and aterm that depend on employment. The result also determined that constant FTG rates,underestimated for small businesses and overestimated for large businesses.To obtain aggregate result for FTG, with industry with constant FTG – the average FTG should bemultiplied by the number of establishment, industry with FTG directly proportional toemployment, the aggregate FTG could be found by multiplying the total employment by the FTGrate, if the disaggregate FTG model includes a constant and an employment term, the aggregateFTG is the summation of the model’s constant times the number of establishments and the totalAssigned Text Weekly SubmissionRavichandra Rampure|215905367 |MASc Civil Engineeringemployment times the coefficient of the employment term. Thus the study suggests that acomprehensive study of the FTG data is required to ensure for the FG-FTG models. The findingalso suggests that in case of the passenger transportation FG-FTG behavior must be verified caseto case.
