This document discusses policies for regulating freight vehicles in cities to reduce their negative impacts. It provides examples from Germany, Hungary, the Netherlands, and China. Germany implemented distance-based tolling for trucks and restricted older, more polluting vehicles from entering cities. Hungary limits truck access based on time, weight, and zone. The Netherlands uses restrictions on time, location, emissions, weight, and noise. China piloted fuel-saving technologies on trucks and aims to optimize freight logistics. Overall, the document advocates for setting clear regulatory goals and understanding local traffic/business conditions to effectively manage urban freight.
