Comprehensive Analysis on the Conversion of the Existing HOV Lanes into Hot Lanes in Tennessee

This study analyzed the conversion of HOV Lanes to HOT Lanes in Tennessee. The research applied several approaches including microsimulations of HOV/HOT Lanes that employed data from Greater Nashville Regional Council (GNRC) travel demand model and field collected traffic counts. Microsimulation was conducted through VISUM and VISSIM software by importing TransCAD based GNRC traffic travel demand. Apart from the comprehensive literature review on HOT Lane effectiveness from other states, the study reviewed best practices from other cities and states on conversion of HOV Lanes to HOT Lanes, enforcement, violation and penalty structures, and policy initiatives. A total of four scenarios were evaluated including:(1) the base scenario with HOV Lanes without effective enforcement as it is currently operated (2) HOV Lanes converted to HOT Lanes with no intermediate access (3) HOT Lanes with one intermediate access point and (4) HOT Lanes with multiple access points along the current HOV Lane corridors. The study found that converting HOV Lanes to HOT Lanes without intermediate access performs better (meaning reduced travel time) when compared to HOT Lanes with additional intermediate entrance/exit points. With HOT Lanes, travel time for all traffic along major interstate highways in Tennessee will be reduced by an average of 23% from the current travel times. Travel time for the traffic that will be using the HOT Lanes along major interstate highways in Tennessee will be much reduced compared to other GP lanes from the current travel times. Key findings from the case studies of other regions and Cities with currently operating HOT Lanes view them as effective means to manage congestion. Given the proper commitment by TDOT, HOT Lanes have the potential to be a better and more efficient usage of resources to relieve congestion on highways than the construction of more general-purpose lanes. Study recommends TDOT convert the current HOV Lanes to HOT Lanes without intermediate access (entrance/exit). The entrance/exit points should be only at the beginning and end of the HOT Lanes. Study recommends a toll fee of 10 cents per mile and tolls should be collected electronically (static or dynamic tolls). Study recommends that separation of the HOT Lanes and GP lanes should be through pavement marking (not physical barriers). Only single occupant vehicles (SOV) will be required to pay tolls, and all HOVs (2+) using the HOT Lane will be exempted from toll payment. Dynamic Message Signs should be initially located 1 mile prior to the starting of the HOT Lane to provide travel alerts and incident information. Video cameras installed along HOT corridors must be used for violators\u2019 identification and incident detection

The Unintended Consequences of Flood Mitigation along Inland Waterways \u2013 a Look at Resilience and Social Vulnerabilities through a Case Study Analysis

69A3551747130This project aims to fill such gaps by developing a model for calculating a Social Fabric Index (SoFI) using publicly available data that is both replicable and scalable. To test the model\u2019s applicability and robustness, it was applied to a case study area and subjected to uncertainty analysis and global sensitivity analysis. The overall objective of this project is to evaluate the unintended consequences of flood mitigation activities (i.e., buyout programs) represented as community costs of measures such as residential home buyouts. While buyouts are used in both coastal and inland communities as a mitigation approach, this study is focused primarily on a case study of an inland riverine community because an inland community may have more alternatives for mitigation than coastal areas (i.e., relocation and elevation may be more amenable options in some inland areas)

Designing information literacy instruction for the life sciences

Information literacy for the life sciences differs from other disciplines and requires an approach that addresses the specific needs of the curriculum and its students. This chapter focuses on the important aspects to consider when designing information literacy for the life sciences, including characteristics of the curriculum and students, opportunities to collaborate with instructors to integrate information literacy, and strategies for developing assessment-based approaches. It provides recommended resources, specific guidance, and practical suggestions for librarians responsible for information literacy instruction in the life sciences disciplines

A novel WFS1 mutation in a family with dominant low frequency sensorineural hearing loss with normal VEMP and EcochG findings

Background: Low frequency sensorineural hearing loss (LFSNHL) is an uncommon clinical finding. Mutations within three different identified genes (DIAPH1, MYO7A, and WFS1) are known to cause LFSNHL. The majority of hereditary LFSNHL is associated with heterozygous mutations in the WFS1 gene (wolframin protein). The goal of this study was to use genetic analysis to determine if a small American family's hereditary LFSNHL is linked to a mutation in the WFS1 gene and to use VEMP and EcochG testing to further characterize the family's audiovestibular phenotype. Methods: The clinical phenotype of the American family was characterized by audiologic testing, vestibular evoked myogenic potentials (VEMP), and electrocochleography (EcochG) evaluation. Genetic characterization was performed by microsatellite analysis and direct sequencing of WFS1 for mutation detection. Results: Sequence analysis of the WFS1 gene revealed a novel heterozygous mutation at c.2054G>C predicting a p.R685P amino acid substitution in wolframin. The c.2054G>C mutation segregates faithfully with hearing loss in the family and is absent in 230 control chromosomes. The p.R685 residue is located within the hydrophilic C-terminus of wolframin and is conserved across species. The VEMP and EcochG findings were normal in individuals segregating the WFS1 c.2054G>C mutation. Conclusion: We discovered a novel heterozygous missense mutation in exon 8 of WFS1 predicting a p.R685P amino acid substitution that is likely to underlie the LFSNHL phenotype in the American family. For the first time, we describe VEMP and EcochG findings for individuals segregating a heterozygous WFS1 mutation.NIH grants DC04945 (V.A.S), DC006901 (V.A.S.) and P30 DC04661 (V.M. Bloedel Core)

Team Paper Category - The application of LIDAR and IMU data to monitor an aerospace craft during its entry, descent, and landing on a planetary body\u27s surface

In modern aerospace applications, the autonomous monitoring of a craft’s motion during the EDL stage of an interplanetary mission has become increasingly important for the mission’s success. Descent tracking data can be used to trigger an autonomous craft’s recovery events, adjust a craft’s descent trajectory, map the topology of a planetary body’s surface, or verify the success of a mission. This paper investigates the reliability and robustness of a descent tracking system that incorporates data collected from both a Light Detection and Ranging (LIDAR) module and Inertial Measurement Unit (IMU). An apparatus has been developed and tested which implements the proposed system and demonstrates its accuracy and usefulness. The LIDAR data is utilized to continuously record the tested vehicle’s distance from a surface with high resolution. IMU acceleration data provides valuable information regarding the dynamics of the craft during its EDL stage (e.g. parachute deployments, landing impact). The studies in this paper suggest that this sensor suite and its associated software allow for closed-loop, real-time, autonomous control
