Introduction Establishment-based freight surveys (EBFS) are a specific data collection process for urban freight operations. The focus of both this research, and of the data collection process, was to investigate vehicle activity at urban retail establishments. This work reports on the formulation, development, application and statistical analysis of an EBFS with a sample of 604 establishments in Lisbon, Portugal. It contributes towards the systematization of the available knowledge and aims to potentially support the process of developing future EBFS as well as to inform researchers and policy-makers of establishments characteristics and delivery patterns. Methods Several statistical analyses were performed to the survey answers' distributions such as Spearman correlations, line / scatter plots and Ordinary Least Squares (OLS) linear regressions. Results New insights into variables' worth are provided, such as the influence of industry category on the vehicle arrivals throughout the day or the influence of the number of employees on the total of weekly deliveries. It is revealed that modeling freight trip generation might be prone to considerable errors, which has implications if EBFS data is to be used in simulation models to test policy alternatives. Conclusions It is concluded that stricter parking policies should be in place to avoid obstruction-causing parking practices. Also, the results support advising further research in the field of load consolidation and on the effect of the ordering process in the total trips generated by a retail establishment.

“…The insights from this analysis may be applied to other cities, especially for cities that are highly dense and have the challenge of managing curb space with high demand, where solving the problem of limited parking spaces cannot be solved by adding infrastructure. This is true for many European cities as well, where over 75% of the population reside in cities [51]. European cities also tend to be older cities of which many were built with more narrow roads where there is already limited space for trucks to navigate.…”

Purpose: This paper assesses the parking needs of freight and service related commercial activities and identifies the role of demand management in mitigating these needs. Methods:To provide a context for the analyses, the authors selected two small commercial areas of about the same number of commercial establishments-one in Troy, NY, and the other in New York City-and applied freight and service trip generation models to estimate the total freight and service traffic generated at these sites. Then, using different assumptions of the amount of time these vehicles spend at a parking location, the authors estimated the number of parking spaces required by time of day under different assumptions of demand management. Results:The results show that parking needs are proportional to the average parking durations. Essentially, the longer the duration the higher the parking needs. In terms of impacts on demand management, the results show that the 100% Off-Hour Deliveries (OHD) program is expected to be the most impactful as it reduces the parking needs by 70-80% during peak hours. In second place, Staggered Deliveries reduces parking needs by about 60% during the peak hours. The third place is occupied by the 30% OHD Scenario and the Receiver-Led Consolidation programs, which are virtually tied, offering about 10-25% reduction. Conclusions:The initial analysis revealed the importance of parking duration as it was shown to be proportional to parking needs; the longer the duration the higher the need for parking. The delivery simulation further bolstered this finding by showing that the optimal case occurs (i.e. minimizing parking duration) the closer the parking location is to the establishment. The further away the vehicle is parked the longer the walking time to the establishment, hence increasing the time the vehicle occupies the parking spot. The strategies applied to the case studies showed that Transportation Demand Management (TDM) strategies are effective in decreasing the number of parking spots needed during peak periods.

“…An Organisation for Economic Co-operation and Development (OECD) study on goods delivery challenges found that because of a lack of awareness and knowledge, many delivery facilities in many cities are ill-designed, including the issue of parking places being too small for freight delivery [7]. A study in Italy noted that a lack of functionality in the size of commercial vehicle parking zones limits the operation of truck parking and leads to the illegal occupation of road space outside the load zone [8].…”

Developing design guidelines for commercial vehicle envelopes on urban streets

Commercial heavy vehicles using urban curbside loading zones are not typically provided with an envelope, or space adjacent to the vehicle, allocated for loading and unloading activities. While completing loading and unloading activities, couriers are required to walk around the vehicle, extend ramps and handling equipment and manoeuvre goods; these activities require space around the vehicle. But the unique space needs of delivery trucks are not commonly acknowledged by or incorporated into current urban design practices in either North America or Europe. Because of this lack of a truck envelope, couriers of commercial vehicles are observed using pedestrian pathways and bicycling infrastructure for unloading activities, as well as walking in traffic lanes. These actions put them and other road users in direct conflict and potentially in harm's way. This article presents our research to improve our understanding of curb space and delivery needs in urban areas. The research approach involved the observation of delivery operations to determine vehicle type, loading actions, door locations and accessories used. Once common practices had been identified by observing 25 deliveries, simulated loading activities were measured to quantify different types of loading space requirements around commercial vehicles. This resulted in a robust measurement of the operating envelope required to reduce conflicts between truck loading and unloading activities with adjacent pedestrian, bicycle, and motor vehicle activities. From these results, commercial loading zone design recommendations can be developed that will allow our urban street system to operate more efficiently, safely and reliably for all users.
