Advanced Transportation Management System (ATMS)

A key component of Transportation Systems Management and Operations (TSM&O), Arterial Management is a specialty of Albeck Gerken, Inc. With a foundation of years of arterial timing plan development, the firm has expanded into active arterial monitoring and management with multiple public sector clients.

An initial step is the monitoring of arterial operations. Travel time and travel time reliability are two indicators of how well an arterial is operating. Using Bluetooth-based travel time monitoring systems, Albeck Gerken, Inc. tracks travel time trends; increasing travel times or worsening reliability indicators reflect the need for field reviews and potential operational adjustments.

In the past, the traditional corridor signal retiming process has been based on a multi-year (3 to 5 years or more) cycle consisting of a major count effort, model development, timing pattern optimization, deployment and fine-tuning, and report development. However, with traffic demands growing annually, these patterns soon become out-of-date. A significant element of arterial management is the continual updating and refining of timing patterns to accommodate the trending changes in traffic. Using information from the travel time monitoring, the traffic signal timing patterns can be targeted for refinement.

With the added pattern library capabilities of modern systems, seasonal timing patterns become feasible. Particularly in Florida, where winter visitors place a significant burden on many of our roads, separate peak and off-peak seasonal plans can be particularly effective in optimizing traffic flow.

In addition, the need to accommodate unique and unusual traffic patterns can also be addressed through arterial management. By performing some pre-planning, scenarios to address traffic demands from special events, major traffic incidents, evacuations, or detours from nearby roadway construction projects can be identified, and appropriate signal operating strategies defined. Special timing patterns are often developed and kept on the system for quick deployment when needed.
