Abstract:

<p> Existing railroad crossing crash prediction and hazard index equations are analyzed and found to inadequately measure safety at light rail crossings. The operational characteristics of common carrier freight and commuter railroads are different enough from the operational characteristics of light rail to affect the ability of existing railroad equations to accurately predict the number of crashes that occur at light rail crossings. These operational differences require light rail specific crash prediction equations to better predict crash numbers at light rail crossings. The goal of this r

<p> Transportation planning is a vital and necessary operation for a metropolitan area to grow. As such, and in order to receive Federal funding for transportation projects, metropolitan areas engage in transportation planning as regulated by MAP-21. One element of meeting MAP-21 requirements is addressing the safety of a region. With new requirements by MAP-21, MPOs must demonstrate some sort of performance measure showing changes in the various elements, making quantitative means of displaying these changes ever more important. </p><p> The goal of this project was to develop a model or se

Abstract:

In this thesis an incident prediction model is formulated and calibrated. The primary idea of the model developed is to correlate the expected number of crashes on any section of a freeway to a set of traffic stream characteristics, so that a reliable estimation of likelihood of crashes can be provided on a real-time basis. Traffic stream variables used as explanatory variables in this model are termed as Ã¢ÂÂincident precursorsÃ¢ÂÂ. The most promising incident precursors for the model formulation for this research were determined by reviewing past research. The statistical model employed

The objective of this research is to evaluate and introduce a new methodology regarding rural highway safety. Current practices rely on crash prediction models that utilize specific explanatory variables, whereas the depository of knowledge for past research is the Highway Safety Manual (HSM). Most of the prediction models in the HSM identify the effect of individual geometric elements on crash occurrence and consider their combination in a multiplicative manner, where each effect is multiplied with others to determine their combined influence.

In 2010, the American Association of State Highway and Transportation Officials (AASHTO) released a safety analysis software system known as SafetyAnalyst. SafetyAnalyst implements the empirical Bayes (EB) method, which requires the use of Safety Performance Functions (SPFs). The system is equipped with a set of national default SPFs, and the software calibrates the default SPFs to represent the agency’s safety performance. However, it is recommended that agencies generate agency-specific SPFs whenever possible. Many investigators support the view that the agency-specific SPFs represent the ag

Abstract:

Recent research has shown that incorporating roadway safety in transportation planning has been considered one of the active approaches to improve safety. Aggregate level analysis for predicting crash frequencies had been contemplated to be an important step in this process. As seen from the previous studies various categories of predictors at macro level (census blocks, traffic analysis zones, census tracts, wards, counties and states) have been exhausted to find appropriate correlation with crashes. This study contributes to this ongoing macro level road safety research by investigating vari

Vehicle crashes at signalized intersections have long been of utmost concern to the transport authorities.

These models are able to calculate the rear-end and lane-change crash risks along the freeway in real-time through the use of static information at various locations along the freeway as well as the real-time traffic data obtained by loop detectors. Since these models use real-time traffic data, they are capable of calculating re

With proper use, VSL can be more cost effective than adding more lanes.

Threat assessment and reliable motion-prediction of surrounding vehicles are some of the major challenges encountered in autonomous vehicles' safe decision-making. Predicting a threat in advance can give an autonomous vehicle enough time to avoid crashes or near crash situations.

Moreover, different driver behaviors pose different kinds of threats. Various driver behavior predictive models have been proposed in the literature for motion predic

Abstract:

The Highway Safety Manual (HSM) estimates roadway safety performance based on predictive models that were calibrated using national data. Calibration factors are then used to adjust these predictive models to local conditions for local applications. The HSM recommends that local calibration factors be estimated using 30 to 50 randomly selected sites that experienced at least a total of 100 crashes per year. It also recommends that the factors be updated every two to three years, preferably on an annual basis. However, these recommendations are primarily based on expert opinions rather than dat

Indiana University-Purdue University Indianapolis (IUPUI)<br>Automotive technology has grown from strength to strength in the recent years. The main focus of research in the near past and the immediate future are autonomous vehicles. Autonomous vehicles range from level 1 to level 5, depending on the percentage of machine intervention while driving. To make a smooth transition from human driving and machine intervention, the prediction of human driving behavior is critical. This thesis is a subset of driving behavior prediction. The objective of this thesis is to predict the possibility of cra

碩士<br>國立中山大學<br>財務管理學系研究所<br>103<br>In this paper, we forecast stock market crashes by innovative EEMD-based neural network approach with stock market indices. The concept of EMD is to decompose nonlinear and nonstationary time series signal for obtaining instantaneous frequency data. In order to predict stock crashes for early-warning proposes, this study uses Ensemble Empirical Mode Decomposition to decompose historical prices into several frequency component and a residual trend, and then take these components as inputs in neural network. The result of our research shows that the prediction

碩士<br>國立政治大學<br>金融學系<br>107<br>This paper analyzes and predicts TAIEX crash events from 2005 to 2018 with JLS model, and increases the predictability by modifying JLS model by including economic factors. After we use the genetic algorithm to optimize the model with economic factors, the result shows that the predictability to a crash and fitting ability are both significantly increased. When analyzing the correlation between error days and stock price features, we find that the length of a period and the growth rate of a stock price are both correlated with the error days. We also find that mo

Accident analysis studies aim at the identification of high rate accident location, safety deficient areas and the accidents prone zones within Rourkela city, using GIS. For this purpose the road accident data for seven consecutive years, pertaining to Rourkela city has to be used. Accident particulars like year, location, type of vehicle involved, are included in GIS database. The buffer function available in the spatial analyst extension of Arc GIS software was to be applied to identify the accident prone areas in Rourkela.

Abstract:

Safety reviews of existing roads are becoming a popular practice of many agencies nationally and internationally. Knowing road safety information is of great importance to both policymakers in addressing safety concerns and travelers in managing their trips. There have been various efforts in developing methodologies to measure and assess road safety in an effective manner. However, the existing research and practices are still constrained by their subjective and reactive nature. The goal of this research is to develop a framework of Road Risk Indices (RRIs) to assess road risks of existing hi
