124 This chapter discusses several illustrative applications of the kind that could be conducted using the models included in the guidebook. The applications describe the use of: • FTG models to estimate commercial parking needs at a commercial center; • FTG models to analyze historic trends using the ZIP Code Business Patterns database; • FTG models to support the development of a freight model at the MPO level; and • FG models to analyze the importance of freight corridors at the state level.

Illustrative applications 125 analysis, one could estimate the number of parking spaces needed to make deliveries. To do so one needs to have an idea about the temporal distribution of deliveries and service activity, and the amount of time that the typical freight and service vehicles spend making a delivery/pick-up or performing a service activity.

Illustrative applications 129 The FTG estimates were put together with other freight-related data to form a dynamic database that allows CDTC to better understand how, why, and where freight moves through the region, to help facilitate the efficient and sustainable movement of goods while maintaining quality of life. The FTG estimates produced enabled CDTC to identify corridors essential to freight movement, and existing barriers to greater efficiency of freight activity.

130 Using Commodity Flow Survey Microdata and Other establishment Data to estimate the Generation of Freight, Freight trips, and Service trips MAP-21 required the designation of a national freight network to assist states in strategically allocating resources to improve freight efficiency. The goals of this freight network designation were to reduce freight transportation delay time and improve reliability for each freight transportation mode through infrastructure improvement, technology development, regulations, and enhancement of multimodal transportation capacity and connectivity, among other methods.

Illustrative applications 131 When interpreting the results it is important to note that (1) these estimates, which correspond to local production of freight, do not include the amount of cargo at border crossings; and (2)
