IMPACTS OF LARGE TRUCK RESTRICTIONS IN FREIGHT CARRIER OPERATIONS IN METRO MANILA

Abstract: Large truck restrictions directly affect freight carrier operations. To estimate truck travel demands, it is necessary to look into the changes of freight carrier operations after the imposition of any truck restriction policy. An understanding of their operational and travel behaviors will be helpful in estimating latent truck demands that are usually neglected in travel demand forecasting. Using data from interview surveys of freight carrier operators, this paper aims to examine the impacts of the existing large truck restriction on their trucking operations. Interview surveys reveal that freight carriers cope with the large truck restriction policy by mainly changing their delivery routes and or shifting their delivery times. Through random utility discrete choice modeling, the paper tries to determine if freight carriers’ reaction depends on specific factors related to company and their operational characteristics.
