Title: Applications of ITS in SD Work Zones
Project Researcher: Jon Becker, South Dakota Department of Transportation
Project Manager: Hal Rumpca
Research Period: 12/1/2003 - 3/31/2004
Status:
Cost: $5,000.00

Problem Statement:

Work zones, traffic incidents and high traffic areas during major events are often places where drivers can become confused or drive aggressively. Such an environment can cause congestion and endanger workers. During the summer months, SDDOT operates many work zones where drivers need to reduce speed, merge, and take extra precautions. These same characteristics are true for arrival and departure traffic at major special events.

ITS solutions are available to provide drivers with advance warning of work zones and traffic congestion. These systems can also provide project and traffic engineers real-time information necessary for timely traffic control. The Indiana Lane Merge system gives motorists instructions such as when to merge to prevent congestion at "bottle neck" areas. Products are also available for warning workers when errant vehicles breach the work zone.

While ITS technology has been researched and evaluated by many agencies, research is needed to inventory SDDOT and other state agencies to determine what traffic control needs exist for work zones and special events, and whether existing equipment can be utilized as a part of an ITS solution such as an early lane merge system or a traffic management system.

Findings:

Research Objectives:
1  To determine SDDOT's needs for traffic control at special events, traffic incidents and in work zones;
2  To investigate existing ITS technologies that will improve traffic flow and worker safety in work zones and special event traffic areas;
3  To determine whether ITS technology should be used by SDDOT for traffic control during special events, and whether existing equipment might be used as a part of ITS traffic control systems.

Research Tasks:
1  Perform a literature search regarding ITS technology in work zones.
2  Perform an equipment inventory of SDDOT, BIT, HP, and Emergency Management to determine the location, model, and condition of traffic control/information equipment.
3  Perform a survey of SDDOT regions and areas to determine requirements for traffic control at special events, traffic incidents and in work zones.
4  Based on the needs expressed by the panel, map appropriate ITS systems to the identified needs, and make recommendation to the panel.
5  Determine whether equipment owned by the state might be used in traffic control or lane merge systems.
6  Meet with the technical panel to summarize literature and findings of ITS technology used in work zones.
7  Provide a final report including methodology, findings, conclusions, recommendations, and architecture deliverables.
8  Make an executive presentation to the Research Review Board.
