A towns public works department is concerned that a certain intersection is dangerous for cars and therefore needs a stop sign. What data could the department collect to prove the need for a stop sign at this intersection?
the number of automobile fatalities per year in the town
the total automobile insurance claims submitted per year by residents of the town
the average number of cars passing through the intersection per hour
the average number of car accidents reported at the intersection per month
Done ->
The average response time for emergency vehicles to reach the intersection from nearby stations.
To prove the need for a stop sign at the intersection, the public works department could collect the following data:
1. The average number of car accidents reported at the intersection per month: This data would provide information on the frequency of accidents occurring at the intersection.
2. The number of automobile fatalities per year in the town: Fatalities related to car accidents can indicate the severity of accidents happening in the town and highlight the need for safety measures like stop signs.
3. The average number of cars passing through the intersection per hour: This data would help determine the volume of traffic at that particular intersection.
4. The total automobile insurance claims submitted per year by residents of the town: Insurance claims can give insight into the frequency and cost of accidents in the town, which can help assess the need for safety measures.
By analyzing the aforementioned data, the public works department can gather evidence that supports the need for a stop sign at the intersection.
To determine the need for a stop sign at a particular intersection, the public works department could collect various data to support their case. Here are some data points that could be useful:
1. The average number of car accidents reported at the intersection per month: This data will help identify if the frequency of accidents at the intersection is higher compared to other intersections in the town. It provides information about the potential danger and the need for traffic control measures.
2. The average number of cars passing through the intersection per hour: This data is important to understand the traffic volume at the intersection. A high volume of cars passing through the intersection can increase the risk of accidents and indicate the need for traffic control measures like a stop sign.
3. The number of automobile fatalities per year in the town: While not directly linked to the specific intersection, collecting this data provides an overview of the overall safety concerns in the town. If the data suggests a concerning number of fatalities, it can be used to argue for additional traffic control measures such as stop signs.
4. The total automobile insurance claims submitted per year by residents of the town: This data can provide insights into the frequency and severity of accidents in the town. If the insurance claims related to accidents near the intersection are disproportionately high compared to other areas, it can strengthen the case for implementing a stop sign as a necessary safety measure.
By collecting and analyzing this data, the public works department can build a solid argument for the need for a stop sign at the intersection. They can present this data to relevant authorities and stakeholders to support the decision-making process.
