“…Disaggregate data for urban freight operations, such as shipment records, is scarce and challenging to obtain. Data are only collected by using costly and infrequent establishment-based surveys, implemented large scale only for a small number of cities in the past (29)(30)(31)(32)(33)(34). Therefore, freight modeling typically requires several assumptions to compensate for the lack of the disaggregated data (35).…”

“…Freight survey design and its applications are summarized by Allen et al (2012), covering establishment surveys, vehicle observation surveys, parking surveys, driver surveys, commodity-flow surveys, roadside-interview surveys, and other surveys. Cheah et al (2017) provided a literature review focused on commodity and establishment-based freight surveys.…”

“…• A large-scale GPS-based vehicle tracking and driver-activity survey to a sample of season parking ticket holders of the Urban Redevelopment Authority heavy vehicle parks to understand movements and parking patterns (Alho et al 2018). • A pilot of a commodity-flow survey in Singapore (Cheah et al 2017), which is being followed by a larger deployment, to understand commodity flows and associated business characteristics. • A shipment-tracking pilot in the USA and Singapore to gain additional understanding of the supply chain structures that shipments go through.…”

“…On the other hand, a lot of efforts and resources were spent on collecting disaggregate data until this day. Several metropolitan-scale establishment surveys, which are also called commodity flow surveys, were conducted in recent years or are currently ongoing for informing urban freight models (Hunt et al 2006;Alho and e Silva 2015;Toilier et al 2016;Cheah et al 2017;Oka et al 2018). Exploring urban freight modeling approaches that make full use of those survey data is one of the important research topics.…”
