Hurricane Charley's Impact on Traffic Equipment and Structures The FDOT Traffic Engineering and Operations Office conducted a Field Damage Assessment Study in the aftermath of Hurricane Charley to estimate the damage to traffic equipment and support structures. Hurricane Charley made landfall on August 13, 2004, in the Punta Gorda/Port Charlotte area of Florida’s southwest coast. At landfall, Hurricane Charley was reported to have sustained winds of 145 miles per hour. The hurricane traveled northeast, through the Orlando area, out into the Atlantic Ocean.
FDOT’s current policy for mast arm traffic signal supports requires that mast arms shall be used on all state road projects within 10 miles of the coastline. However, many of the FDOT District Offices are installing mast arm traffic signal supports on projects further inland than 10 miles. Indications from the study are that the mast arm signal supports survived significantly better than the strain pole/span wire configuration.
Several hundred photographs were taken during the field study to provide illustration of the structural failures of numerous signing and high mast lighting assemblies.

Traffic-signal Crews Start All Over The cost to fix traffic signals damaged during Hurricane Jeanne in Palm Beach County could reach $10 million, double the toll inflicted by Frances, a state transportation official said Tuesday. After Frances it was estimated it would take months to get traffic in the county running smoothly. But after Jeanne, repairs will take even longer because of a shortage of parts. Combined with the damage from Hurricane Charley on the west coast and Ivan in the Panhandle, there's not enough signals available to go around. At many intersections, the span wires that held up the signals were ripped down. "There are no more signal heads in the United States until more are manufactured," said Rick Estripeaut, operations manager for the Florida Department of Transportation. State and county crews are still assessing how many signals were lost or broken when Jeanne roared through last weekend. But there's no doubt the strike was much more severe than Frances, Estripeaut said. In Martin, St. Lucie and Indian River counties, signal damage from Jeanne could cost $50 million. "Frances was a hard hit, but nothing that bad," Estripeaut said. "With Jeanne, we lost (entire) intersections." About 25 percent to 30 percent of the county's 1,100 intersections are still without power, County Engineer George Webb said. Most are in the north end of the county. Law enforcement officers are directing traffic at some of the major intersections. At others, stop signs are in place to remind motorists that traffic must stop in all directions. More than two dozen state crews are assisting county workers to survey damage from Jeanne. It will be a few days before a complete report is compiled. After Frances, a two-step plan was initiated to return traffic signals to normal operations. The first step was to make sure a working signal was in place in each direction at every intersection. In some places, generators were used to run signals until power was turned back on. The second phase was to replace missing lights and fix others that were broken. The work was expected to take several months. Repair crews had barely scratched the surface to fix signals damaged during Hurricane Frances when Jeanne came along, Estripeaut said. Now, it's back to step one again. "All we're trying to do is keep people alive," he said. "We need to get the infrastructure back up so people can get to work. The damage could have been worse if crews had not taken preventative action. Before Jeanne arrived, about 600 newer traffic signals were taken down around the county to save them from hurricane-force winds.

LeeWay Variable Pricing — Saving Time and Money The LeeWay program is Lee County’s electronic toll collection system. This program provides advantages to weekday motorists that travel these two toll bridges by reducing their travel time and reducing the cost of the toll. Variable pricing is one of the strategies that can be used by transportation engineers that provides travelers with financial incentives to alter their travel patterns. Another benefit of variable pricing is that it often provides a positive effect on traffic patterns by removing some of the total traffic from the peak travel periods. Reducing congestion reduces costs to the traveler and, in the case of LeeWay, also reduces the cost paid for the toll. Central to the concept of variable pricing is the willingness of motorists to voluntarily modify their travel patterns. Those that volunteer to modify the time of travel across the bridges get a discount in the cost of the toll. The LeeWay variable pricing program discounts tolls by 50 percent during the periods that have discount pricing available. These periods are outside of the traditional morning, mid-day and evening peak periods. For example, if a weekday commuter traveling the Cape Coral Bridge alters their morning travel time to the variable pricing hours of between 6:30 and 7:00 a.m., they would receive a 50 percent toll discount. On these bridges the variable pricing hours during weekdays are from 6:30 to 7:00 a.m.; 9:00 to 11:00 a.m.; 2:00 to 4:00 p.m.; and 6:30 to 7:00 p.m. The LeeWay variable pricing program was developed initially from the Federal Highway Administration's (FHWA) Value Pricing Pilot Program and went into full operation in 1998. The number of motorists participating in the program has steadily increased and there are now about 95,000 vehicles with transponders. Transponders are read by antennas at the toll plaza, which communicate with the vehicle transponder and automatically deduct the toll amount from the transponder owner’s prepaid account. The transponders permit unattended toll collection enabling vehicles to travel through a toll plaza without stopping, which provides an increase in the overall number of vehicles that can be serviced at the toll plaza. The LeeWay program has evolved and expanded over the years and several significant enhancements in electronic payment services have been completed, while more are planned. Currently, LeeWay has enhanced capabilities to operate with SunPass® and the LeeWay transponders are accepted throughout the state of Florida. Other planned enhancements to the LeeWay program include transponder compatibility with the SunPass and E-Pass® programs used in other regions of the state of Florida. There are also future plans to install automated enforcement capabilities and to install a data connection from LeeWay tolls to Lee County’s traffic management center to provide enhanced information exchange. The LeeWay variable pricing program has saved motorists about $2.5 million to date in discounted tolls and provides improved travel by reducing traveler delays. Further information on LeeWay can be obtained at www.leewayinfo.com.

11th World Congress on ITS Summary Vehicles and Typhoons—A Uniquely Japanese Event
The Congress Opening set the tone for the Congress – equal parts substance and style. The session, staged at the Aichi Prefecture Arts Center (prefectures are equivalent to states), included Japanese dancing and drum performances along with the usual array of dignitaries celebrating another year of progress in the ITS industry and highlighting the Congress theme “ITS for Liveable Society.” The opening portion of the three-hour session was conducted in the presence of Their Imperial Highnesses Prince and Princess Akishino. The various elements of the Congress got into full swing on the second day, with concurrent executive sessions, special sessions on selected topics of interest, scientific sessions, technical sessions, interactive poster board sessions, technical tours, and multiple exhibit halls impressive both in size and scope. As one would expect, the Japanese were the largest block of attendees and exhibit spaces, and the sessions leaned heavily on Japanese speakers to share project and research results. As a single delegate, it is impossible to participate in all activities offered by the organizers, but from what I did participate in, some of the major “take aways” for me were:
Knowing I would be writing this summary, I asked some other attendees for their succinct impression of the Congress:
All in all, the Congress, as always, provided an excellent opportunity to compare and benchmark US efforts to improve transportation operations through technology with those in other countries/regions. In particular, the deep look into Japanese programs is extremely useful. The previous real opportunity for such an examination last occurred in 1995, the last World Congress held in Japan.

Lane Departure Warning Technology: A “Wake-up” Call for Today’s Drivers The national figures are staggering. Statistics just don’t lie. The shattered life of a family coping with the automobile-related death of a loved one numbers more than 100 every day. Approximately 3 million people are injured because of the 6.3 million traffic accidents that occur in the United States each year—roughly 17,000 daily. Some of those involved are able to walk away from the scene easily, while many others fall victim to a mangled wreck of twisted metal, shredded rubber, and minced glass as vehicle crashes claim the lives of more than 40,000 people in this country each year. And while auto fatalities devastate and often destroy the families of loved ones lost on America’s highways, traffic deaths also elicit an inevitable question of hindsight...what if? Accident prevention has become such an integral part of the American automotive safety landscape because, unlike the grim realities of incurable disease and natural disaster, neither of which are avoidable, many traffic collisions can be eluded and fatalities prevented. Those families of loved ones lost on America’s highways are too often left to grapple with what may have been an avoidable collision and consequently, a preventable death. Numerous studies indicate that drowsy or inattentive drivers are primarily to blame for the nation’s single largest cause of highway fatalities—unintended lane departures. According to the U.S. Department of Transportation (DOT), more than 43 percent of all traffic fatalities are related to unintended lane departures. The findings are backed by research conducted by the National Highway Traffic Safety Administration (NHTSA), which found that nearly half of all fatal traffic accidents reported in 2001 involved a lane or road departure attributed to distraction, fatigue, or some other lapse in driver concentration. In addition to the natural driver fatigue that causes drowsiness, the explosion of cellular telephone usage while driving contributes to yet another accident-yielding condition—driver distraction. Even hands-free dialing and steering-wheel-mounted call answering still engage the driver in conversation, rendering him or her incapable of maximum vehicle focus. Likewise, a large majority of automobiles and heavy trucks today come equipped with advanced audio features, navigation systems, and climate controls that require involved operation, limiting a driver’s ability to maintain road and traffic concentration if the vehicle is in motion. But as technology often can be prone to creating products with attached issues and sometimes-hazardous ramifications, technology frequently and rapidly creates an antidote with an equal level of efficiency. Airbags, lap and shoulder belts, crumple zones, and child safety seats certainly have played a prominent and effective role in not only addressing, but also reducing, the number of fatalities caused by traffic accidents. Yet one issue still lingers over motoring safety like the steam hovering above a smashed radiator...how many traffic accidents can be avoided altogether? Sadly, it is the same question that over 100 American families are faced with each day. If the loss of human life isn’t crushing enough, avoidable accidents devastate on many other levels. While the personal cost due to lost lives and injuries remains incalculable, the total economic cost of traffic accidents in the U.S. stood at $230 billion two years ago, according to data published by NHTSA. The national figures are staggering. Statistics just don’t lie. They are conclusive and indisputable. They also are increasing. There is a light, or this case, a loud awakening sound at the end of the tunnel. Enter technology. As advanced technology plays a significant role in the distraction of drivers, ironically, it will also play a critical role in the solution. According to DOT estimates, a broad range of diverse technologies, known collectively as ITS, ultimately have the capacity to eliminate more than one million crashes per year. In addition, DOT predicts savings of $26 billion in lost productivity, thanks to ITS applications. Obviously, the key to the efficacy of ITS is significant market penetration on national and international levels. Anaheim, CA-based Iteris, Inc. originally developed lane departure warning (LDW) technology for use on commercial trucks because of the long distances typically traveled and the driver’s susceptibility to fatigue and drowsiness that could result in an unintended lane departure. In the simplest of terms, LDW systems installed on trucks have delivered life-saving wakeup calls to inattentive, drowsy, or otherwise distracted drivers in the untimely event of an unintended lane departure. Moreover, the LDW systems are designed to provide the alert to drivers drifting out of their lanes in enough time to correct the situation in a controlled manner. The alert sounded by the LDW system is nearly identical to the sound of a vehicle crossing a rumble strip. In a 1999 report to the U.S. Congress by the National Center on Sleep Disorders, shoulder rumble strips were the only effective devices in alarming or awakening drowsy drivers. In fact, actual rumble strips placed on the outside of the highway have been proven to reduce accidents caused by lane departures by as much as 55 percent. LDW technology has been successful in the European commercial truck market since 2000, when Mercedes began installing LDW technology in its Actros trucks. MAN, a trucking manufacturer also based in Europe, now offers the technology as optional equipment on its new trucks. In the U.S., both Freightliner L.L.C. and International Truck and Engine Corp. offer customers LDW technology as a factory-installed option.
No advance in technology can ever take the place of driver preparedness, concentration, and awareness. But as long as there are automobiles on the highway, there will be those that inevitably become drowsy, distracted, or just purely undisciplined behind the wheel. However, advances in road-safety electronics, especially LDW technology, will go a long way in protecting not just those of us who are lucky enough to have our vehicles equipped with the LDW system, but those who also share the highway with us. The national figures do not have to be so staggering. Statistics may not lie, but they can change to tell a different story. This article was provided by Chester Chandler, Iteris, Inc.

Editorial Corner – A Quantum Leap Forward for Hurricane Evacuation in Florida In 1999, when Hurricane Floyd forced the massive evacuation of two million people in the state of Florida, the State Emergency Response Team (SERT) endeavored to better integrate ITS into its operations at the State Emergency Operations Center (SEOC). That event made the utility of having real-time traffic information for critical segments along the statewide evacuation roadway network even more evident to the state agencies involved with hurricane response. The SEOC also saw the major advantages associated with having the communications capabilities, again using the state’s ITS infrastructure, with evacuating motorists already on the road. Thanks to the experiences from Hurricane Floyd, FDOT and the Division of Emergency Management (DEM) redoubled their efforts to make ITS a viable tool for managing hurricane evacuation operations. The first major step to realizing this goal was to develop an access program to integrate the real-time traffic data collected by the telemetered traffic monitoring system (TTMS). The TTMS was created when FDOT and DEM selected or emplaced 50 traffic counters located specifically to collect data in near real-time at strategic points on the state’s evacuation network. During hurricanes, these real-time sensors provide data for each direction of travel: hourly traffic counts; the hourly average speed; and a historically typical hourly count. The data from up to 30 counters are then assimilated and displayed on a Web site that provides a map of each sensor in relation to the state roadway network. During an evacuation event, each TTMS traffic counter is represented by an icon that, when selected, presents data for every hour of operation in evacuation mode. In a related effort, FDOT’s ITS Program, the Statistics Office, the iFlorida project and the Emergency Management Office, in alliance with DEM, has developed a redundantly operating network of roadway traffic cameras, again, specifically located in support of evacuation operations. These traffic cameras are co-located with a limited number of TTMS sensors and display images on the same Web site. Although this effort is in the early stages of realization, all of the above entities are integrating their efforts to develop a statewide system that utilizes each other’s architecture to collect and transmit this data to the SERT and SEOC. The next step for exploiting ITS data for hurricane evacuation operations is to develop a traffic analysis capability using the real-time roadway data. To accomplish this, DEM, in association with various FDOT offices, is creating a program that develops travel demand forecasts specifically for evacuations and relates those figures against the numbers collected from the roadways during an actual hurricane event. The Hurricane Evacuation Analysis and Decision Support Utility Program (HEADS UP) predicts vehicle demand and the resulting traffic congestion on each segment of the evacuation roadway network based on the evacuation decisions of various counties throughout the state. The program also compares the expected evacuation traffic volumes against the real-time figures captured by the TTMS and furthermore provides data on queue lengths, travel times to host shelter locations, and evacuation shutdown criteria. The FDOT ITS Program currently plans to integrate HEADS UP into the Emergency Evacuation (EE) module of the SunGuideSM Software, the statewide information software for transportation management centers (TMCs) throughout the state.
The ITS capabilities proved absolutely invaluable to the SERT during each of those evacuation events. As evacuations were underway, the TTMS traffic counter and average speed data clearly defined when evacuations began in various regions throughout the state and for how many hours they continued. The counter data also confirmed the anticipated bottlenecks, a result of having the travel demand forecast data, and it provided insights into how long the congestion would last. The average speed figures provided by the counters allowed the SEOC to better prepare counties for their possible roles as host shelter locations. The congestion forecasts, developed for the evacuation roadway segments, were used to create public service announcements and other types of communication to better prepare and inform evacuees of roadway conditions, alternate routes, shelter resources, and other traveler advisories. During Hurricane Frances, the SERT estimated that county officials directed approximately 2.8 million people to evacuate. Despite the possible 1.2 million vehicles on the road as a result of those decisions, all were able to successfully reach their ultimate safe destinations regardless of the distance they traveled on the evacuation roadway network. The other hurricanes in 2004 caused somewhat smaller evacuations in terms of overall numbers, but they also posed serious operational issues with respect to traffic congestion and management. Nonetheless, the same success stories were reported for every hurricane evacuation event in Florida for the 2004 season. The new capabilities provided to the SERT and the SEOC by the ITS infrastructure had an important role in ensuring that the state’s response to the massive travel demand in each event was pro-active and effective. With each new component of the ITS architecture brought on-line, Florida moves closer to realizing its goal of asserting a greater degree of control over evacuations. The addition of more real-time cameras on the evacuation roadway network; the emplacement of the innovative measures included in the iFlorida project; the advent of HEADS UP; the integration of TMCs with the SunGuide Software; as well as the deployment of more highway advisory radios, dynamic message signs, and 511 systems will all revolutionize evacuation operations. Florida’s cooperative and innovative approach of using a wide array of ITS measures to specifically address evacuation and other emergency operations will result in significant enhancements to the safety of citizens and travelers in this state. Florida’s comprehensive ITS deployment plan will also establish the template all other states can use to integrate their traffic operations and emergency functions, regardless of the types of hazards they face.
