New this year: All papers must include a structured abstract in the required format, instead of a traditional (unstructured) abstract, to support faster and more consistent review. This is one of several new requirements intended to facilitate reviewer assignment and evaluation. This format will also help annual meeting attendees identify sessions of interest. Review the instructions for authors for full details and preparation guidance.

HealthTran Rides is a program of the Missouri Rural Health Association. It helps people in 42 counties make non-emergency healthcare-related trips. There is no cost to the rider and volunteer drivers are reimbursed for milage. Vehicles used meet safety standards and drivers are qualified per state and local regulations. Patients can get a lift within minutes or medical providers can schedule a journey up to a month in advance. Rides are scheduled efficiently, with greater vehicle use, giving patients in remote areas more consistent access to transportation.
The number of rides have increased along with patient satisfaction. Trip frequency, patient no-shows, and service delivery times all are moving in the right direction. As HealthTran significantly improves access to medical services, fewer appointments are missed and they’ve enhanced overall health outcomes for residents.

Land Line Media's article on state laws allowing heavier freight loads notes where Owner-Operator Independent Drivers Association points to studies from the TRB and the U.S. Department of Transportation that show that heavier trucks may not equate to fewer trips, less traffic and lower emission.
The Traveler covered FAA-requried ground delays at Phoenix Sky Harbor amid air traffic controller constraint. The article referencing recent government audits and National Academies research highlight rising overtime costs and a higher workload at key facilities.
