Initiative 40: Driver Training Programs Driver Training Programs Description: Programs to improve deliveries by altering driver behaviors and enhancing driver competencies. Drivers' attitudes and behaviors can directly affect delivery efficiency, energy consumption, environmental impacts and the safety of all road users. Driver training programs vary according to their specific goals, which may include noise reduction, energy efficiency or economic driving (also known as eco-driving, which is more environmentally friendly and fuel efficient). Training can include presentations, vehicle checks, driving assessment, driver debriefs, demo drives, and knowledge tests. On completion, participants receive written assessments and certificates.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
