Estimating Truck Parking Demand: Tools and Techniques
In the first part of our series, we explored the importance of truck parking and the factors influencing its demand. Now, let’s delve into how to accurately estimate truck parking demand. Understanding where, when, and why truck drivers need to park is crucial for developing effective solutions. This part will highlight key tools and techniques outlined in the FHWA’s Truck Parking Development Handbook.
Understanding Truck Parking Demand
Every community has different generators of truck parking demand. Local manufacturing, warehousing, and distribution activities depend on timely trucking service, which in turn depends on designated and predictable truck parking. Even in communities with relatively low industrial activity, retail business, agriculture, natural resource extraction, and through traffic on a major highway can lead to high truck parking demand.
Key Factors Influencing Parking Demand
Industrial Activities: Warehousing, manufacturing, and distribution centers generate significant truck traffic, necessitating nearby parking facilities.
Through Traffic: Major highways with high truck volumes require rest areas and truck stops to accommodate long-haul drivers.
Community Characteristics: Local regulations, land use policies, and available infrastructure all influence parking demand.
Tools for Estimating Truck Parking Demand
Several tools and studies provide insights into estimating truck parking demand:
NCFRP Research Report 37: This report uses Commodity Flow Survey data to estimate freight trip generation rates and peak parking demand.
SHRP2: The Strategic Highway Research Program provides data on freight flows and truck trip generation in specific regions.
MAG Truck Parking Study: This study uses GPS data to estimate parking activity rates by land use.
FHWA’s Truck Parking Demand Estimation Tool: This tool helps planners estimate the peak number of trucks requiring parking based on employment and industry data
Case Studies Highlighting Estimation Techniques
Winston-Salem MPO: This study developed truck trip generation equations based on the number of truck bays at facilities.
Texas A&M Transportation Institute: This study analyzed off-site parking generated by industrial land uses in Texas and Maryland.
Limitations of Estimation Tools
While these tools provide valuable insights, they have limitations:
Regional Variations: Data from one region may not be directly transferable to another.
Industry Specifics: Different industries generate varying levels of truck traffic and parking demand.
Data Limitations: Studies may overrepresent large fleets and not account for independent owner-operators.
Conclusion
Accurately estimating truck parking demand is crucial for developing effective solutions. The FHWA’s Truck Parking Development Handbook provides valuable tools and techniques for this purpose. In the final part of this series, we will explore strategies for developing truck parking facilities and overcoming common challenges.
