Battery-powered electric buses are gaining popularity as an energy-efficient and emission-free alternative for bus fleets. However, battery electric buses continue to struggle with concerns related to their limited driving range and time-consuming recharging processes. Fast-charging technology, which utilizes dwelling time at bus stops or terminals to recharge buses in operation employing high power, can raise battery electric buses to the same level of capability as their diesel counterparts in terms of driving range and operating time. To develop an economical and effective battery electric bus system using fastcharging technology, fast-charging stations must be strategically deployed. Moreover, due to the instability …

Much has changed in the 30 years since non-motorized modes were first included in regional travel demand models. As interest in understanding behavioral influences on walking and policies requiring estimates of walking activity increase, it is important to consider how pedestrian travel is modeled at a regional level. This paper evaluates the state of the practice of modeling walk trips among the largest 48 metropolitan planning organizations (MPOs) and assesses changes made over the last 5 years. By reviewing model documentation and responses to a survey of MPO modelers, this paper summarizes current practices, describes six pedestrian modeling frameworks, and …
Utah Salt Storage Facilities Guidelines And Best Management Practices, Weston Bellon
Utah Salt Storage Facilities Guidelines And Best Management Practices, Weston Bellon
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
An environmental analysis was conducted at the Utah Water Research Laboratory of samples gathered from Utah Department of Transportation (UDOT) salt storage facilities retention ponds across the state. The analysis indicated high levels of TSS largely made up of minerals directly associated with the deicing solution currently used by UDOT in roadway applications. As a companion to that analysis, best management practices have been identified and compiled to provide a resource for the proper management of salt storage facilities in the state of Utah. Topics included as best management practices include locating new storage facilities, proper salt storage, proper salt …
