Transportation Systems Management and Operations, or TSMO, is how the Alaska Department of Transportation & Public Facilities (DOT&PF) uses operations, technology, data, and coordination to improve the safety, reliability, and performance of Alaska's transportation system.
TSMO focuses on getting the best performance from the transportation infrastructure we already have. It brings together activities that have often been managed separately, including traveler information, road weather, traffic signals, work zones, incident response, maintenance operations, and intelligent transportation systems.
In Alaska, an operational problem can become a statewide travel problem quickly. On many highways there is no practical detour. A closure, rapidly changing storm, avalanche, wildfire, or long incident queue may separate communities and delay emergency response, freight, and essential travel. TSMO helps turn field conditions into coordinated action and useful public information.

Alaska's transportation system operates across long distances, extreme weather, limited alternate routes, and a mix of urban, rural, and remote communities. A crash, avalanche, wildfire, work zone, or severe storm can affect travel far beyond the immediate location. Timely information and coordination help DOT&PF, emergency responders, local agencies, commercial carriers, and travelers make safer decisions.
TSMO gives DOT&PF a practical way to improve daily operations while larger capital projects are planned and built. It also helps the department consider operational needs early in planning, design, construction, maintenance, and technology investments.
DOT&PF completed its statewide TSMO Strategic Plan in 2024. The plan establishes a common direction for making TSMO part of the department's normal practices and identifies strategies in arterial management, data collection, incident management, road weather, work zones, traveler information, emergency operations, and workforce development.
That work is already taking shape through modernization of Alaska 511, statewide dynamic message sign management, improved construction-impact reporting, road-weather and winter-operations tools, connected infrastructure, and stronger links among field equipment, central software, maintenance staff, communications staff, and partner agencies.
A camera, signal, weather station, or message sign is maintained as part of a public service, not simply as installed equipment. The service includes communications, software, data, staffing, and operating procedures.
Connecting regional systems and field reporting gives operators, maintenance staff, responders, and communications teams a more consistent picture of conditions and disruptions.
Operational needs, ownership, cybersecurity, maintenance, replacement, and performance are considered early so a system can keep delivering value after construction is complete.
Alaska 511 brings together road conditions, closures, cameras, weather, construction impacts, and incident information so travelers can make informed decisions before and during a trip.
DOT&PF can manage dynamic message signs statewide, improve how events move into 511, and develop more coordinated responses to crashes, closures, work zones, weather, and other disruptions.
Road-weather observations, maintenance reporting, vehicle-location information, and field communications help crews understand conditions across a system that is too large to observe from any single location.
