Stochastic Analysis for Work Zone Crash Safety on Roads

This presentation undertakes a stochastic analysis of crash safety in work zones on roads, examining the critical issue of accidents in construction areas. The research investigates accident patterns, identifies contributing factors such as casual driving and overspeeding, and explores the need for improved safety standards. The methodology includes both qualitative and quantitative approaches, incorporating literature reviews and statistical analysis of survey responses. The presentation outlines the research plan, expected findings (such as the correlation between driving at night, overspeeding, and crashes), and potential outcomes, including a reduction in work zone crashes and enhanced traffic rule enforcement. The study aims to provide a holistic view of the global scenario and offer practical recommendations for minimizing the issue, ultimately contributing to improved safety in work zones.

CRASH SAFETY IN WORK
ZONES ON ROAD

INTRODUCTION
 AS OF 2007, 835 PEOPLE WERE KILLED, AND OVER A TOTAL OF
41,000 INJURED AS A RESULT OF WORKZONE CRASHES,
WORLDWIDE (McAvoy, Duffy and Whiting 2011).
 STUDY SUGGESTS THAT THE MAJORITY OF THE PEOPLE WHO
HAVE SUFFERED THE FATALITIES, LOST THEIR LIVES IN
CONSTRUCTION ZONES (Sorrock, Ranney and Lehto 2016).
 NONE OF THE ACCIDENTS WHICH OCCUR IN SUCH SITUATIONS
CAN BE BLAMED ON THE CASUALTIES OF THE POLICE (Sanford
Bernhardt, Virkler, and Shaik 2017).
 MOST STATES HAVE TRAFFIC RULES AND LAWS, WHICH ALSO
INCLUDE OVERSPEEDING.

INTRODUCTION
 THE RESEARCH PAPER WILL BE BASED ON FIGURING OUT WHY
EXACTLY MOST OF THE ACCIDENTS IN WORKZONES OCCUR.
 SPECIFICALLY, THE RESEARCH WILL ADDRESS THE NEED TO
IDENTIFY THE PATTERNS IN WHICH THE ACCIDENTS OCCUR, AND
AIM AT COMING UP WITH RECOMMENDATIONS TO MINIMIZE THE
SAME.
 METHDOLOGY TO SUIT THE REQUIREMENTS OF THE RESEARCH
AND THE PLAN OF THE RESEARCH WILL BE CHOSEN
ACCORDINGLY.

Risk Analysis Chart

STATISTICS
 380 CRASHES OCCURRED IN 359 WORKZONES IN MARYLAND,
2015 (Sekula et al. 2018).
 DEVELOPING COUNTRIES LIKE PAKISTAN HAVE A WORKZONE
SAFETY STAJNDARD, WHICH IS FAR BELOW THE STANDARDS
ACCEPTED WORLDWIDE (Rashid et al. 2018).
 SPEED CONTROL MEASURES ARE NOT FOLLOWED IN A MAJORITY
OF HIGHWAY WORKZONES, WHICH CALLS FOR INCREASED
NUMBER OF CRASHES IN THESE AREAS (Rashid et al. 2018).
 ONLY ONE IN FOUR PROJECTS HAVE WARNING SIGNS PROVIDED
FOR PEDESTRIANS (Rashid et al. 2018).

AIMS
 TO FIGURE OUT THE TRENDS IN THE ACCIDENTS WHICH OCCUR
IN THE WORKZONE AREAS.
 TO FIGURE OUT THE CHANCES OF FATALITIES RESULTING FROM
WORKZONE CRASHES.
 TO CLARIFY WHETHER THE ACCIDENTS OCCUR DUE TO
CASUALTIES IN THE LAW, THE VICTIMS, OR CANNOT BE
ATTRIBUTED TO ANY.
 TO COME UP WITH A HOLISTIC VIEW OF THE SCENARIO ON A
GLOBAL SCALE.
 TO COME UP WITH RECOMMENDATIONS FOR MINIMIZING THE
ISSUE.

OBJETIVES
 TO FIND OUT THE PERCENTAGE OF WORKZONE AREAS WHICH HAVE MINIMAL
STANDARDS OF SAFETY REQUIREMENTS.
 TO DETERMINE THE NUMBER OF FATALITIES THAT OCCUR IN A HUNDRED
ACCIDENTS THAT OCCUR IN THE WORKZONES.
 TO DETERMINE THE SPECIFIC TIME OF THE DAY WHEN THE ACCIDENTS
OCCUR BIN THE WORKZONES.
 TO CONDUCT AN EXTENSIVE LITERTURE REVIEW TO PROVIDE A HOLISTIC
VIEW OF THE SCENARIO, WORLDWIDE.
 TO DETERMINE THE CORRELATION BETWEEN VARIABLES LIKE TIME OF THE
DAY, CASUAL DRIVING AND LACK OF SAFETY REQUIREMENTS, AND
WORKZONE CRASHES.
 TO ANALYSE THE TRENDS AND FINDINGS OBTAINED FROM THE RESULTS, AND
FORMULATE MITIGATION STRATEGIES TO COMBAT EACH OF THE ISSUES.

METHODOLOGY
 THE METHODOLOGY WHICH WILL BE ADOPTED FOR THE
PURPOSE OF THIS RESEARCH IS MOSTLY QUALITATIVE IN
NATURE.
 QUANTITATIVE ANALYSIS WILL BE USED TO ANALYSE THE
SURVEY RESPONSES TO DETERMINE PATTERNS IN THE
ACCIDENTS, AND CALCULATE OTHER CORRELATIONS.
 LITERATURE REVIEW WILL BE THE MAIN FORM OF QUALITATIVE
ANALYSIS.
 QUANTITATIVE ANALYSIS WILL BE BASED ON STATISTICAL
CALCULATIONS.

JUSTIFICATION FOR THE
METHODOLOGY
 FOR A HOLISTIC VIEW, IT IS IMPORTANT THAT EXISTING
LITERATURE IS REVIEWED IN ORDER TO GET AN IDEA ABOUT THE
SCENARIO ON A GLOBAL SCALE.
 QUANTITATIVE DATA WILL ONLY BE HELPFUL IN ANSWERING THE
“WHAT” FACTOR, AND NOT THE “WHY” FACTOR.
 SIMILARLY, QUALITATIVE ANALYSIS WILL ONLY ANSWER THE
“WHY” FACTOR, BUT NOT THE MAJOR TRENDS AND NUMBERS TO
GIVE SPECIFIC INSIGHTS INTO THE PROBLEM.
 THIS IS WHY, BOTH OF THE METHODOLOGIES WILL BE ADOPTED
FOR THE RESEARCH.

PLANS
 USING RANDOM SAMPLING, PEOPLE WILL BE ASKED IF THEY
KNOW ANYONE OR HAVE PERSONALLY EXPERIENCED WORKZONE
CRASHES.
 RESPONDENTS WHO GIVE A POSITIVE FEEDBACK, WILL BE SENT
A QUESTIONNAIRE.
 THE QUESTIONNAIRE WILL BE DESIGNED IN A WAY THAT
FACILITATES QUANTITTATIVE INFORMATION.
 FOR EXAMPLE: RESPONDENTS WILL PROVIDE DEGREES TO
WHICH THEY AGREE OR DISAGREE TO A PARTICULAR QUESTION.
 BASED ON THE RESULTS, CORRELATION WILL BE CALCULATED ON
EACH CRITERIA TO UNDERSTAND THEIR RELATIONSHIP WITH THE
ISSUE.
