REPRESENTATIVE PROJECTS
WAWA Convenience Stores, PA, NJ, DE, VA & MD
TPD has been working with Wawa for over 30 years, building a strong partnership with the rapidly expanding chain, having been involved in our 600 projects serving them. Because of Wawa’s exclusive use of TPD for traffic engineering services in eastern and central Pennsylvania, TPD is able to prepare traffic impact studies, traffic signal designs, roadway designs, and Highway Occupancy Permits (HOP) Plans that quickly and efficiently meets the needs of each individual Wawa location. Based on this experience, TPD has been recognized as the experts in the traffic operations of their convenience store with gasoline prototype facility. TPD authored an article that was published in the August 2001 edition of the ITE Journal entitled Trip Generation Characteristics of Convenience Stores. The article studied 28 operating Wawa convenience stores with gasoline facilities and discussed that current trip generation methodologies outlined in the ITE Trip Generation Manual do not apply to this new type of land use. The article has been accepted by ITE, PennDOT, and Townships and has resulted in lower traffic impact fees incurred by Wawa.
Sheetz Convenience Stores, Various Location in PA
TPD has been forging a dynamic relationship with Sheetz over the last 5 years. Our growth is mirrored with theirs, as we have provided transportation services for 25 Sheetz projects in Pennsylvania.
