Traffic Engineering Multiple Choice Questions on “Accident Studies – 1”.
1. Which of the following is not an objective of accident studies?
a) To evaluate existing design
b) To compute the financial losses incurred
c) To study the root cause of accidents and propose corrective measures at potential location
d) To collect data regarding parking demand
Answer: d
Clarification: To collect data regarding parking demand is not an objective of accident studies. To evaluate existing design, to compute the financial losses incurred, to study the root cause of accidents and propose corrective measures at potential location are some of the objectives of accident studies.
2. What is the first step in the accident study?
a) Accident data collection
b) Accident investigation
c) Accident data analysis
d) Accident reconstruction
Answer: a
Clarification: The first step in the accident study is accident data collection. This data collection is generally done by the police. Motorists accident reports are considered secondary data.
3. Which of the following information does not require an accident data collection report?
a) Identification of spots at which unusually high number of accident happen
b) Development of a method that allows identification of risks before accidents occur
c) Comprehensive functional assessment of critical accident location to identify the causes of accidents
d) Development of parking areas
Answer: d
Clarification: Development of parking areas does not require accident data collection report. Identification of spots at which unusually high number of accident happen, development of a method that allows identification of risks before accidents occur, and comprehensive functional assessment of critical accident location to identify the causes of accidents are some of the information that requires accident data collection report.
4. The development of different statistical measures of various accident-related factors gives insight into which of the following factors?
a) Causes of accidents
b) Location of points at which unusually high number of accident takes place
c) Identification of hazards
d) Driver profiles
Answer: d
Clarification: The development of different statistical measures of various accident-related factors gives insight into driver profiles. It also gives insight into general trends and common casual factors.
5. Which of the following parameters given below is not required in accident data collection?
a) Registration number
b) Details of road geometry
c) Financial losses suffered due to property damage
d) Sight distance
Answer: d
Clarification: Sight distance is the parameter that is not required in an accident data collection report. Registration number, details of road geometry, and financial losses suffered due to property damage are some of the parameters that is required in an accident data collection report.
6. Which of the following are the methods of reporting in accident studies?
a) Motorist accident report
b) Car accident report
c) Road accident report
d) Highway accident report
Answer: a
Clarification: A motorist accident report is a method required for reporting in an accident study. The motorist accident report is filed by the motorist involved in the accident. Another method, police accident report is also used for reporting.
7. A police accident report is filed by _________
a) attendant police officer
b) motorist involved in the accident
c) witnesses of the accident
d) relatives of the motorists involved in the accident
Answer: a
Clarification: A police accident report is filed by an attendant police officer. This report includes fatal accidents that require emergency or hospital treatment or which have suffered massive property damage.
8. Which of the following procedure of accident data collection involves obtaining information such as measurement of skid marks?
a) At Scene-Investigation
b) Reporting
c) Technical Preparation
d) Cause Analysis
Answer: a
Clarification: At Scene-Investigation is the procedure of accident data collection that involves obtaining information such as measurement of skid marks. It also gives information regarding the photograph of the final position of vehicles, the examination of the condition and functioning of traffic control devices, and examination of damage of vehicles.
9. In which procedure determination of critical and design speed for curves is done?
a) At Scene-Investigation
b) Reporting
c) Technical Preparation
d) Cause Analysis
Answer: c
Clarification: Technical Preparation is the procedure in which the determination of critical and design speed for curves is done. This procedure is required for planning and interpretation of the study. It also involves measurement of grades and sight distance.
10. In which of the following procedure accident reconstruction is involved?
a) At Scene-Investigation
b) Reporting
c) Technical Preparation
d) Professional Reconstruction
Answer: d
Clarification: In professional reconstruction process accident reconstruction is involved. In this step, attempt is made to determine from the data available on how the accident occurs from the accessible data.
11. What is the purpose of Accident data analysis?
a) To find possible causes of accident-related to driver, vehicle, and roadway
b) To evaluate existing design
c) To compute the financial losses incurred
d) To collect data regarding parking demand
Answer: a
Clarification: The purpose of Accident data analysis is to find possible causes of accident-related to driver, vehicle, and roadway. Accident analyses are made to develop information such as drivers, pedestrians, vehicle, and roadway.
12. Why is it important to compute accident rates?
a) Because it reflects accident involvement by type of highway
b) Because it reflects accident involvement by type of drivers
c) Because it reflects accident involvement by type of pedestrians
d) Because it reflects accident involvement by type of design conditions
Answer: a
Clarification: It is important to compute accident rates because it reflects accident involvement by type of highway. These rates compare the safety of different highway and street systems and traffic controls.
