▼ Ramp metering has been successfully implemented in many states and studies have documented its positive mobility and safety benefits. However, there have been no studies on the use of ramp metering for work zones. This thesis reports the results from the first deployment of temporary ramp meters in work zones in the United States. Temporary ramp meters were deployed at seven work zones in Missouri. Due to lack of crash data, this study uses video data to extract alternative safety measures such as driver compliance, merging behavior, speed differentials, lane changing, and braking maneuvers. This evaluation suggests that temporary ramp meters should only be deployed at work zone locations where there is potential for congestion and turned on only during periods of high congestion. In comparison to over 90% compliance rates of permanent ramp meters implemented in other states, field data showed compliance rates from 40.5% to 82.9% in temporary ramp meter. This suggested that non-compliance could be a major safety issue in the deployment of temporary ramp meters. The use of a three-section instead of a traditional two-section signal head used for ramp metering produced significantly higher compliance rates. This thesis then aggregated the data into groups to further analyze the effects of different factors such as platoons, commercial trucks, work zone type and work zone-ramp configuration. After analyzing general characteristics of mainline and ramp vehicle speed and speed differentials, this study then focused on findings for different comparison groups. The two comparison groups are "between two work zones" versus "before work zone" configuration and "left-lane closed" versus "right-lane closed" work zone type. Results indicated lower mean speeds of mainline and ramp vehicles and higher differentials when ramp metering was turned on. This is expected and again temporary ramp meters are recommended only where congestion occurs. Congestion will lead to lower mainline speeds thus lower speed differentials either with or without ramp metering. Finally, analysis of merging headways showed that temporary ramp meters were effective in separating platoons before vehicles merged into mainline. This produces more single-vehicle merging which requires shorter gaps and causes fewer impacts on the mainline traffic. Advisors/Committee Members: Edara, Praveen K. (Praveen Kumar) (advisor).

▼ [ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Connected vehicle technology is a wireless system to support communication for enhancing safety and mobility. The thesis proposes a single-link connected vehicle probe data (CVPD) model to estimate travel time on urban arterials. This research applies VISSIM to simulate probe vehicles that can generate and assemble snapshots via installed On-Board Unit (OBU). Each snapshot, which can include link identification, instantaneous speed, location and time, is generated by a generation protocol. Generation protocols can be changed by system operators to allow data collection to be tailored to specific situations. In theory, generated snapshots are added to the buffer in OBU and they will not be removed until the snapshots are transmitted to roadside equipment (RSE). However, actually, the space of buffer is limited. If the buffer became full and the probe vehicle does not travel into the range of a RSE, a recorded snapshot must be deleted to make room for a new snapshot. Under snapshots deletion condition, CVPD model may miss some useful data and hence estimate link travel time inaccurately. In order to save buffer's space, the number of recorded snapshots should be as small as possible. A new snapshot generation protocol, the protocol, is proposed in this thesis and its performance is compared with two existing protocols – the fixed observation interval protocol and the society of automotive engineers (SAE) protocol. The core of protocol is to only capture the vehicle snapshots when dramatic changes in acceleration take place. The dramatic changes are defined by predefined acceptable ranges based on different buffer space sizes. In this research, three kinds of buffer spaces are defined, which can provide enough space to save snapshots assembled by fixed observation protocols, including fixed-two-second (F2), fixed-four-second (F4) protocol, and SAE protocol, respectively. Two travel time estimation methods were used to estimate travel times from the generated snapshots – the time-speed plot method and the average speed method. The time-speed plot method relies on interpolation functions to fit time-dependent speed observations obtained from snapshots. Three piecewise different interpolation functions were investigated in this thesis – Linear interpolation, Cubic Spline interpolation and Cubic Hermite Spline interpolation. In this research, ten variations of protocol are proposed. Three of them are selected to compare the snapshots generated by F2, F4 and SAE protocol, respectively. The main objective of protocol selection is the number of collecting snapshots is equal to or less than F2, F4 and SAE protocol, respectively. Comparing F2, F4 and SAE, the number of snapshots recorded by the protocol reduces 30.11%, 26.02% and 4.39%, respectively. Two-tailed p-value and t-statistic are applied to analyze mean absolute relative error (MARE) of entire traffic network link travel time estimated by time-speed plot method and average speed method.

▼ [ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Research shows that a high percentage of crashes that take place on high-speed rural expressways occur at intersections with minor roads. One low-cost alternative design for improving safety of at-grade intersections on such expressways is the J-turn. In the last few years the Missouri Department of Transportation has converted some two-way stop controlled (TWSC) intersections into J-turns. In a TWSC intersection on a four lane divided highway vehicles accessing the major highway from the minor road could make a left turn or through movement at the intersection by crossing the major road movements. On the other hand, in a J-turn design vehicles accessing the major highway from the minor road make a right turning movement and then use a U-turn at a downstream location. The major road vehicles accessing the minor road via a left turning movement may or may not have to use the U-turn for their movements. This study evaluated the effectiveness of J-turn intersection design in Missouri using field studies, a public survey, crash analysis, and traffic conflict analysis. The field studies collected detailed video data at a J-turn site and a control site. The crash analysis included a statistically rigorous Empirical Bayes (EB) before-after safety evaluation. The EB study found that the J-turn design resulted in a 30% reduction in the crash frequency for all crashes and a 47.9% reduction in the crash frequency for all injury and fatal crashes. Both reductions were statistically significant at the 95% confidence level. The disabling injury crashes and minor injury crashes per year decreased by 86% and 45%, respectively. None of the five sites had a fatal crash occur after the J-turn was implemented. The elimination of fatal crashes and a significant reduction in disabling injury crashes are substantial safety improvements offered by the J-turn design. One of the most severe crash types, the left turn right angle crashes was completely eliminated by the J-turn. Rear-end, sideswipe, and passing crashes also decreased post Advisors/Committee Members: Edara, Praveen K. (Praveen Kumar) (advisor).

▼ [ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Incentive/disincentive clauses (I/D) are designed to award payments to contractors if they complete work ahead of schedule and to deduct payments if they exceed the completion time. A previously unanswered question is, "Did the costs of the actual work zone impacts that were avoided justify the incentives paid?" This paper answers that question affirmatively based on an evaluation of 20 I/D projects in Missouri from 2008 to 2011. Road user costs (RUC) were used to quantify work zone impacts and included travel delays, vehicle operating costs, and crash costs. These were computed using work zone traffic conditions for partial‐closure projects and detour volumes and routes for full‐closure projects. Conditions during construction were compared to after construction. Crash costs were computed using Highway Safety Manual methodology. Safety Performance Functions produced annual crash frequencies that were translated into crash cost savings. In considering an average project, the percentage of RUC savings was around 13% of the total contract amount, or 444,389 of 3,464,620. I/D provisions were very successful in saving RUC for projects with full-closure, projects in urban areas, and emergency projects. Rural, non-emergency projects successfully saved RUC but not at the same level as other projects. The I/D contracts were also compared to all Missouri Department of Transportation contracts for the same time period. The results show that I/D projects had a higher on-time completion percentage and a higher number of bids per call than average projects. But I/D projects resulted in 4.52% higher deviation from the project budget and possibly more changes made after the award. A survey of state transportation departments and contractors showed that both agreed to the same issues that contribute to the success of I/D contracts. Overall, in terms of work zone impact mitigation, I/D contracts are very beneficial at a relatively low cost. Advisors/Committee Members: Sun, Carlos (advisor), Edara, Praveen K.

▼ [ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Hurricane evacuation has attracted renewed emphasis since hurricane Katrina in 2005. Every coastal state is establishing their evacuation guidelines and searching new methods to improve evacuations. In this dissertation, first, hurricane evacuation of the Hampton Roads region of Virginia is investigated using large-scale regional mesoscopic traffic simulation models. Fourteen evacuation scenarios consisting of various combinations of storm categories and traffic control strategies are evaluated. The evaluation of scenarios provided information on the clearance time, average travel times, bottleneck locations, and congestion durations. The major findings from scenario evaluations include: (1) The differences in participation rates (100% versus 70%) did not impact the clearance times in a Category 1 storm evacuation, but have significant impact in a Category 3 storm evacuation, (2) The status (open or close) of a critical tunnel crossing, the Monitor-Merrimac Memorial Bridge-Tunnel did not have impact on the evacuation performance in Category 1 and 2 storm. However, opening the tunnel would improve the performance in a Category 3 storm, (3) The clearance times derived from simulations can be used to determine when to issue evacuation orders for various storm intensities, and (4) The bottleneck locations and durations identified for each evacuation scenario can be used to allocate the limited traffic monitoring equipment during an evacuation. The second focus of this dissertation is to investigate the impact of assumptions made regarding evacuee route choice on evacuation performance estimates. In the hurricane evacuation literature, very few studies have documented the realistic route choice behavior of evacuees during a hurricane. Due to this lack of realistic route choice behavior data, modelers make assumptions about the route choice behavior and traffic assignment. User-equilibrium traffic assignment has been extensively used in past evacuation studies. In this dissertation, realistic route choice behavior was determined by evaluating findings of a few published studies. The impact of route choice behavior on evacuation performance, especially travel times, is then investigated using the regional simulation model of the Hampton Roads region. The analysis found that the user-equilibrium traffic assignment significantly underestimates the travel times during an evacuation. The extent of underestimation of evacuation travel times depends on the total evacuation demand (a function of storm intensity), and the percent of evacuees willing to use en-route information to seek alternate routes when facing congestion. For the three en-route percentages reported in the literature i.e., 30%, 50%, and 70%, the UE travel times were 58%, 42%, and 33% lower than actual travel times realized in a Category 1; 94%, 71%, and 57% lower in a Category 2; and 90%, 69%, and 54% lower in a Category 3 evacuation. These findings illustrate the need to collect real-world… Advisors/Committee Members: Edara, Praveen K.

▼ [ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Over the past decades environmental sustainability and mitigating congestion has been a significant challenge in urban areas in many countries. Freeway traffic management systems are aimed to improve traffic conditions by better managing existing freeway facilities. This dissertation presents an evaluation methodology that consists of series of statistical tests to identify the changes in flow-occupancy plot and flow breakdown on freeways. Two-dimensional Kolmogorov-Smirnov test was used to examine the statistical significance of changes in the overall flow-occupancy distribution. Curve-fitting techniques were used to produce before and after flow-occupancy fitted plots. In order to compare the fitted plots, statistical tests were presented to identify if slopes of fitted lines were statistically different. One challenge in creating traffic flow plots is the identification of critical occupancy. An automated procedure based on clustering techniques was presented to alleviate the modeler discretion from identifying the critical occupancy value. The impact of freeway traffic management systems on the probability of flow breakdown was also investigated. A non-parametric product-limit method and parametric Weibull distributions were used to model flow breakdown distributions. The applicability of presented methodologies for evaluating the freeway traffic management systems was illustrated using two case studies; a variable speed limit system in St. Louis, Missouri, and a freeway ramp metering system in the Twin Cities, Minnesota. The two-dimensional Kolmogorov-Smirnov test was illustrated to be useful in identifying the changes in before and after study of flow-occupancy distributions. Clustering techniques were successfully applied to partition traffic data to two regimes and to create flow-occupancy diagrams and to identify flow breakdown. Finally, an examination of the breakdown probability distribution highlighted its values as a more complete performance measure than capacity or critical occupancy.
