Selection of a simulation software to model a small signalized system of a multilane arterial in the southeastern US

Employment of traffic simulation tools has become a popular practice in traffic operations analyses as the transportation system has become more complex and more frequently congested. Most of the commercially available traffic simulation models work best for free-flow or unsaturated conditions. Depending on the type of traffic condition and type of analysis, the performance of simulation models varies and there is little information available to help the analyst to select the most appropriate and accurate model for a given analysis. To address this need, two traffic simulation tools, SimTraffic and AIMSUN, were evaluated and compared for a congested arterial segment. Both simulation packages are designed to model almost any combination of surface street and freeway facilities. In this paper, an arterial segment in Tuscaloosa, Alabama (McFarland Boulevard) between 13th street and 31st street was coded and simulated for AM, Mid day, and PM peak periods. The network was simulated 10 times for each peak period using both simulation models, and average values were taken for comparison. Then the network was evaluated using output measures of effectiveness (MOE) such as Vehicle Hours Travel (VHT), Vehicle Miles Travel (VMT), average speed, and flow rate at the network level, along with delay, travel time, and average speed at the arterial level, and delay and traffic volume at a link level. Using statistical methods and graphical plots for comparison, each simulation model was evaluated for its capability to replicate existing field conditions using default and calibrated traffic parameters. In addition to accuracy, the models were also compared with respect to ease of coding, and quality/usefulness of output. This report documents relevant results and calibration processes used for employing the models in future studies and practices regarding congested arterials.

Transit evacuation planning for Mobile County, Alabama

The main objectives of this thesis research were to: (1) estimate the potential number of transit dependent individuals during a major hurricane event and (2) provide information describing how to effectively communicate with these individuals before, during and after an emergency evacuation. Mobile County was used as a case study. Mobile County is one of the two Alabama coastal counties exposed to the effects of hurricane storm surges, wind and rain. The amount of danger the residents face depends on the intensity of hurricanes, the locations of the individuals, and the amount of prior preparation and planning by emergency agencies. During these events special needs individuals are the primary endangered people since they require special assistance to evacuate and are not usually included in emergency evacuation plans. Since special needs populations are diversified, and mostly isolated, it is difficult to identify, locate and communicate emergency information with them. The study reviewed several reports and guidebooks published by federal and state emergency management agencies. This review was supplemented by contacting individuals working in the area of emergency management and evacuation of special needs populations. The study identified a variety of communication systems which can be applied in emergency information communication. The systems' limitations and strengths in serving the special needs individuals were assessed based on the literature. The number of potential transit dependent populations was estimated in three ways. Each method used a different dataset: (1) Census 2000, (2) 2006 American Community Survey and (3) Harvard Telephone Survey. There were several major findings for this part of the study: 1. There was a general correspondence between the three estimates, but it was not strong enough to make a statistical comparison. 2. The census data and American Community Survey data contain large standard errors, as much as ±30% at a 90th percentile confidence level. 3. The actual numbers of evacuees for previous categories 3 and 2 hurricane events near Mobile County were less than 11% of the average predicted levels. In summary, this study provided information to assist Mobile County prepare evacuation plans to deal with extreme events. (Published By University of Alabama Libraries

Development of the pilot car driver certification program for Alabama

Oversize and overweight loads are an essential part of the economy and current life. Unfortunately, with these loads comes a potential danger to the public. Roads, bridges, and railroad crossings are not built to support these loads or allow for easy access. Pilot car escorts are an essential element to safely and efficiently moving the oversize loads. These escorts have the responsibility of keeping the public and load safe. Yet, only eleven states have training and certification requirements for the driver of the escort vehicle. Alabama is not one of these eleven states. The Alabama Department of Transportation (ALDOT) partnered with the University Transportation Center of Alabama (UTCA) to develop a program. This thesis documents the development of the Alabama Escort Driver Certification Program and focuses on the development of the curriculum. For the escort driver certification program to be effective, The Code of Alabama must be updated to include certification requirements. After extensive research, UTCA staff recommended changes to The Code of Alabama to update the rules and regulations regarding pilot/escort driving. UTCA also suggested course logistics such as course instructors, course availability and locations, class size, budget, proof of certification, and course evaluation. UTCA then developed a one day (eight hour) curriculum based on Florida's current curriculum. Participants must attend the course, demonstrate proper flagging technique, and pass a written exam with a minimum score of 80% to receive certification. The thesis also describes the multi-media presentation, instructor's manual, and participant's manual's content format and content. The development of a website to serve as a media for advertisement and a registration aid is also presented. This report documents relevant information and decisions made in the development of an important and possibly life-saving program. (Published By University of Alabama Libraries
