With increased connectivity between vehicles, sensors, systems, shared-use transportation, and mobile devices, unexpected and unparalleled amounts of data are being added to the transportation domain at a rapid rate, and these data are too large, too varied in nature, and will change too quickly to be handled by the traditional database management systems of most transportation agencies. The TR...

Collecting paper load delivery tickets at highway construction projects is an outdated practice that exposes construction inspectors to many safety hazards.

Public transit buses face many operational challenges—especially when operating on the same streets and roads as other vehicles. Buses can be slowed by traffic congestion and get repeatedly caught at traffic lights, slowing buses down and delaying both passengers on board and passengers waiting at stops farther along the route. The TRB Transit Cooperative Research Program's TCRP Synthesis 149: ...

Accurate traffic forecasts for highway planning and design help ensure that public dollars are spent wisely.

Sixty-eight percent of the states who responded to a survey indicated their agency has a documented process for as-built development. They said handwritten notes were the most commonly used method to capture as-built data (86%), followed by electronic notes (76%), and then photographs (33%). Some states use more than one option to capture as-built data. The TRB National Cooperative Highway Rese...

Automatic passenger counters (APCs) provide passenger boarding and alighting information associated with time and location data. They are a standard tool used by many transit authorities to measure and report monthly ridership to the National Transportation Database, with resulting federal subsidies calculated solely based on the data they provide. The TRB IDEA (Innovations Deserving Explorator...

Transit agencies in the US use four primary communications mechanisms to dispatch, monitor and manage the operations of their mobile assets: private radio systems, Wi-Fi communications, cellular communications, and track circuits and signaling. Most data communications in the transit industry today are still based on vendor proprietary communications protocols and messaging. This limits agency ...

The Wisconsin DOT issues both single- and multi-trip permits for Oversize–Overweight (OSOW) vehicles.
