Problem 2 (30%) Visit the Connecticut Crash Data Repository Dashboard at www.ctcrash.uconn.edu. Use the emphasis areas tool to find out how many DUI involved crashes were reported in the town of Mansfield in 2022 and 2023. What is the total number of crashes? How many were fatal? How many involved non-fatal injuries? What time(s) of year did most of the crashes occur? What time of day and day of the week did most of the crashes occur? Show the data you use to answer these questions.

Why is there a need to investigate an incident? How are effective accident reports created? What is the benefit of accomplishing one?

1. Discuss considerations for the design and operation of on or off-road facilities for bicyclists and pedestrians. 2. Given the physical characteristics of an intersection and its crash history, identify important safety problems and suggest methods that can be taken to remedy them. 3. Construct a Haddon matrix to itemize factors relevant to a road crash from a narrative description of a crash and a location diagram or map. 4. Discuss sustainability issues with regard to transportation, especially related to automobile dependency, the brown and green sustainability agendas, and the three revolutions in mobility.

Give a quick summary of the risk assessment methodology used by transportation experts.

3. What are the nine crash factors used in the analysis of a crash event?

The accident investigation is a legal requirement. It also aims to prevent a repetition of the same accident in the future. Point out the information of a good incident investigation report should provide.

Why is it necessary to look into an incident? How do accurate accident reports get written What are the advantages of completing one?

Need type answer a. A section of road has 55 accidents recorded in three years. For the same period, the estimated vehicle travel on the section was 23 mvk. Considering only those sections having the same characteristics as the section under study, the mean rate is 80 accidents per 100 mvk. Is the section hazardous with 90 percent level of confidence? b. Based on the graph of the accidents time per day on ‘explain’, what time makes up the most number of accidents? Discuss and explain why the frequency of accident is high.

Determine the severity number for a section of highway that had 2 fatal crash, 48 personal injury crashes, and 105 property damage only crashes during a particular time period. Use a weighting scheme of 50 for fatal crashes, 25 for personal injury crashes, and 1 for crashes with only property damage. Determine the severity index by dividing the severity number by the total number of crashes, thereby normalizing the severity number by the number of crashes.

The accident rate for 100 million vehicle miles of travel is 9.8. The length of the road is 15 mileswith an ADT of 67,000. Determine the estimated yearly reduction in total crashes if the crashreduction factor is one third.
