Ken Morefield is Retiring From FDOT! After 31 plus years with the FDOT, Ken Morefield is retiring from his current position as Assistant Secretary for Transportation Policy. His responsibilities include the areas of Design, Construction, Maintenance, Planning, Public Transportation, and Motor Carrier Compliance. He is also the Governor’s Highway Safety Representative. Ken came to the Central Office from District 2, where he served as Secretary. He has also held positions as State Highway Engineer (Chief Engineer) and State Roadway Design Engineer. He has provided distinguished service by serving on several AASHTO committees and the Jacksonville Transportation Authority Board during his FDOT tenure. For some time, Ken has strongly felt the requirement for better management of Florida’s roadways, especially during the evacuation efforts for Hurricane Floyd in 1999. “The need for an ITS Office was quite apparent. No one knew where the traffic was! Dynamic message signs and some cameras, including a few at key intersections in the rural areas, would have been most helpful in providing motorists with information and delay times,” he related. With his support, the FDOT ITS Office was initiated in July of 2000, with just two FDOT staff. The FDOT ITS Office has grown to consist of six FDOT staff who manage an ITS general consultant and a telecommunications general consultant. Altogether, 17 people are collocated with the FDOT ITS Office staff providing a variety of technical and support functions for the FDOT ITS Office’s daily operation. Additional resources can immediately be engaged as needed. Great
strides have been made in bringing ITS to the forefront at the District
executive level,” Ken says. “The Department
must continue to work toward a collaborative effort between the local
District needs and the Central Office in establishing integrated traffic
management statewide. The key is the transferability of control between
transportation management centers.” Ken says his major ITS accomplishments are the establishment of the FDOT ITS Office’s ITS Program and the adoption of the Ten-Year ITS Cost Feasible Plan (Plan) with dedicated dollars for the deployment of ITS components. His future vision for ITS in Florida is the actual implementation of the Plan in the best and fastest manner possible. He cites the Road Rangers and the Incident Management Programs as examples of the successful progress toward better management of Florida’s roadways. “I am happy with our technical progress and think the Department needs to strongly support the program in the future--deal with the established plan and not abandon the goal of completion.” Far from taking up a rocking chair, Ken will continue to toil in the transportation arena. He steps directly into a new position on March 1, with Jacobs Engineering Group, Inc., with statewide responsibilities for design and construction engineering and inspection. Ken will continue to be based in Tallahassee. The FDOT ITS Office wishes to thank Ken for his guidance and support; we wish him well in his new endeavors.

ADDCO's Innovative ITS Project in Florida Will Shorten Delays and Enhance Safety A The project utilizes an innovative Portable Intelligent Transportation System (PITS) in conjunction with a lane-widening project along Interstate 4. One lane in each direction will be added to ultimately provide a 29.5 mile improved 6-lane interstate through Polk County (outside of Orlando to Lakeland). Beginning this fall, the project is expected to last approximately 31 months. It is the goal of the FDOT, the construction contractors, the engineering firm – DRMP, and ADDCO to make the work zone as safe and congestion-free as possible during the entire length of the project. Contracted by DRMP for FDOT, ADDCO is deploying a variety of equipment to collect information on traffic conditions and correspondingly relay this information to motorists in a variety of ways. ADDCO’s traffic operators will be able to see real-time traffic conditions from cameras mounted on various portable platforms. ADDCO will also collect data from microwave sensors indicating roadway speeds and volumes. Real-time information will then be shown on dynamic message signs. Using highway advisory radios, motorists will also be able to access this information on several radio stations. ADDCO is responsible for the design, installation, maintenance, and onsite operation of the system for the duration of the project.
ADDCO will deploy and operate a variety of solar-powered ITS equipment incorporating wireless communications, signage, cameras, and sensors. The fully portable fleet of equipment may be moved around the work zone as needed. Traffic will be monitored on a 24/7 basis by ADDCO. Equipment deployed includes the following:
ADDCO will use its own software package, Virtual Transportation Operations Center (VTOC©), to seamlessly integrate and control all devices. Using this software will optimize information flow and help ensure that motorists have accurate, current information throughout the entire work zone. This article was reprinted with the permission of ADDCO. For more information, please contact Lisa Dumke at (651) 558-3579 or email LRDumke@addcoinc.com.

The University of Florida’s “Top Down” Central Data Warehouse Research Project The combination of real-time ITS and legacy transportation-related data can be used as a powerful tool for providing tourists, commuters, government agencies, and private entities with timely on-demand transportation information. Florida’s Statewide Intelligent Transportation Systems Architecture (SITSA) contains a central data warehouse (CDW) component in its statewide concept of operations. The principal function of a CDW is to collect and store statewide information from many data sources and make the information available for use for various purposes. The FDOT initiated a feasibility study for a CDW to determine the uses of data generated and used by various ITS applications in Florida and to provide preliminary recommendations on the configuration and functionality of a CDW. This feasibility study is being performed by the University of Florida. The current research for the feasibility study by the University of Florida contains:
This subsequent phase of research uses a “top down” structure of a statewide CDW. The top down structure will include FDOT enterprise application data incorporated with data collected by the FDOT Districts. Currently, the University of Central Florida is performing “bottom up” research of a real-time ITS CDW for iFlorida, the Surface Transportation Security and Reliability Information System Model Deployment project. This research is structured primarily around regional Florida data and will also be included in the top down structured CDW. This will provide a prototype CDW which will fully address legacy and real-time ITS data. This prototype CDW will meet interoffice, interagency, and inter-department ITS data warehouse requirements, especially for emergency evacuation and statewide homeland security. This prototype CDW will interface with data provided by the FDOT Offices of Information Systems, Safety, Planning, Traffic Operations, and Maintenance. This prototype CDW will also interface with other local, state, and federal agencies identified in the SITSA. This article was provided by Liang Hsia, FDOT ITS Office.

Planning For Implementation of Transit Signal Priority Signal Preemption vs. Signal Priority
Lessons Learned One of the first lessons learned was that pedestrian considerations cannot be ignored. It was discovered that some signal controllers allow preempt phases to truncate the pedestrian clearance interval. Pedestrian clearance intervals should never be compromised to provide transit priority. Pedestrian clearance intervals and vehicle minimums determine just how much transit priority can be given. Most agencies that have implemented transit signal priority limit the amount of extended green or early green to 10 seconds so that pedestrian clearance can still be accommodated and a reasonable phase length is still provided for all phases. One of the most significant lessons learned was that, despite the manufacturers’ claims, many existing legacy signal controllers simply cannot accommodate both signal preemption and signal priority. In some cases, the transit vehicle’s call to the signal controller initiated a signal preemption rather than an extended green or early green. In other cases, the signal controller did not support enough signal preemptions to accommodate the different needs of both emergency vehicle preemption from various directions and transit vehicle priority. Another lesson learned was that an existing traffic control system may impose constraints upon the implementation of transit signal priority. In the case of the Broward County Traffic Engineering Division’s test, the existing urban traffic control system would not allow for extended greens. Therefore, as they work towards implementing transit signal priority on some of their corridors, the best that can be offered is the early green.

Editorial Corner – Public Health and Transportation Public health and transportation are topics not usually discussed together by transportation professionals. On January 12, 2004, I attended the Matson Distinguished Speaker Luncheon during the Transportation Research Board 83rd Annual Meeting in Washington, D.C. The Distinguished Speaker was Dr. Howard Frumkin, Professor and Chair of the Department of Environmental and Occupational Health at the Rollins School of Public Health at Emory University and Professor of Medicine at Emory School of Medicine. The topic of his presentation was “Active Living and Transportation Impacts.” Dr. Frumkin identified a number of areas where the decisions we make while planning, designing, constructing and operating our transportation systems affect public health. For example, noise pollution caused by freeways can cause stress, which in turn can cause high blood pressure and heart problems. Stress is also caused by traffic congestion. Freeway air pollution can cause respiratory problems such as asthma. Dr. Frumkin’s presentation made me think of the work that we do with ITS and the operation of these systems. While there are many planning and design considerations that could be discussed, I prefer to concentrate on considerations during construction and operation. Consider a freeway without ITS. There are no detectors to provide information on traffic flow. Incidents are identified when someone calls 911. Response is dispatched after police verify the incident and determine the type of response that is needed. Motorists do not get any information on the reason for the unusual slowdown of traffic and are not given alternative routing information. In such a situation, freeway travelers would be more stressed and subjected to increased air pollution. Those residents living near the incident would also be subjected to increased air pollution. It does not matter whether the incident was in a construction zone or not. The effect would be similar although it might be more severe in a construction zone because of reduced roadway facilities. Now consider a freeway with ITS. Detectors would help identify incidents and closed-circuit television would be used to verify incidents. Response would be dispatched quickly and not be reliant on on-site verification. This would significantly reduce the amount of time that motorists and surrounding residents would be subjected to stress and increased air pollution. The World Health Organization (WHO) through its Regional Office for Europe recently prepared a report on Transport, environment and health (Transport, environment and health, edited by Carlos Dora and Margaret Phillips, WHO Regional Publications, European Series; No. 89, 2000). This report discussed the effects of noise, accidents and injuries, and air pollution on mental health and well-being. Noise can be defined as unwanted sound. At low travel speeds, engine sounds are heard. At high speeds, tires and the roadway surface are the predominant cause of noise. The effects of noise on health were identified as impaired communication, disturbed sleep, difficulties with performance, annoyance, increased aggression, heart disease and hypertension, and hearing impairment. Traffic emits significant quantities of airborne pollutants from motor exhaust gases as well as from tires, brakes, and the roadway. The effects of air pollution include discomfort from unpleasant smells, respiratory inflammation, breathlessness, heart and circulatory problems, and lung diseases and cancer. A recent report estimated that there were 80,000 deaths per year in European cities related to long-term exposure to traffic-related air pollution (Charter on Transport, Environment and Health, EUR/ICP/EHCO 02 02 05/9 Rev. 4, 16 June 1999). In 2002, there were about 40,000 motor vehicle-related fatalities in the United States (National Overview of Recent Highway Safety Data, National Highway Traffic Safety Administration, DOT HS 809 482). In 1999, there were about 120,000 motor vehicle-related fatalities in the WHO European Region (Charter on Transport, Environment and Health). These are an unacceptably high number of fatalities. While it may not be possible to eliminate accidents, they can be reduced. About one-third of all freeway accidents are secondary accidents, which are often more severe than the primary accident. Reducing the time it takes to detect, verify, respond, clear, and recover from an incident can reduce secondary accidents. The use of ITS and improved operations can significantly reduce secondary accidents and improve public health. In general, the effects of transportation on health and well-being include post-traumatic stress from accidents, aggression and nervousness, reduced social life, and constraints on child development. One of the functions of our government is to promote public health, safety, and welfare. Those agencies with active ITS and operations programs are the ones that partially fulfill this function. Those that do not, should be made aware of the societal benefits of an active ITS and operations programs. Use of ITS and active operations of these systems is a step in the right direction towards improving public health. This editorial was provided by Walter H. Kraft, PB Farradyne.
