Introduction

As a community activist, gathering data to support an initiative to have a traffic light constructed at a busy intersection near a school is crucial. The primary goal is to ensure the safety of students and other road users. In this analysis, we will use mathematical concepts to evaluate the need for a traffic light at the intersection.

Problem Statement

A community activist is gathering data to support an initiative to have a traffic light constructed at a busy intersection near a school. On average, 100 vehicles pass through the intersection every hour. The activist wants to determine the probability of a vehicle passing through the intersection during a specific time frame.

Mathematical Concepts

To solve this problem, we will use the following mathematical concepts:

Probability: The likelihood of an event occurring.
Frequency: The number of occurrences of an event within a given time frame.
Rate: The frequency of an event per unit of time.

Calculating the Probability of a Vehicle Passing Through the Intersection

Let's assume that the activist wants to determine the probability of a vehicle passing through the intersection during a 30-minute time frame. We can use the following formula to calculate the probability:

P = (Number of vehicles passing through the intersection during the time frame) / (Total number of vehicles passing through the intersection per hour)

Step 1: Calculate the Total Number of Vehicles Passing Through the Intersection per Hour

We are given that 100 vehicles pass through the intersection every hour. Therefore, the total number of vehicles passing through the intersection per hour is 100.

Step 2: Calculate the Number of Vehicles Passing Through the Intersection During the Time Frame

Since we want to determine the probability of a vehicle passing through the intersection during a 30-minute time frame, we need to calculate the number of vehicles passing through the intersection during this time frame. We can use the following formula to calculate the number of vehicles passing through the intersection during the time frame:

Number of vehicles passing through the intersection during the time frame = (Total number of vehicles passing through the intersection per hour) x (Time frame in hours)

Step 3: Calculate the Probability of a Vehicle Passing Through the Intersection During the Time Frame

Now that we have calculated the number of vehicles passing through the intersection during the time frame, we can use the formula for probability to calculate the probability of a vehicle passing through the intersection during the time frame:

P = (Number of vehicles passing through the intersection during the time frame) / (Total number of vehicles passing through the intersection per hour)

Solving the Problem

Let's assume that the time frame is 30 minutes, which is equal to 0.5 hours. We can use the following values to calculate the probability:

Total number of vehicles passing through the intersection per hour = 100
Time frame in hours = 0.5

Step 1: Calculate the Number of Vehicles Passing Through the Intersection During the Time Frame

Number of vehicles passing through the intersection during the time frame = (Total number of vehicles passing through the intersection per hour) x (Time frame in hours) = 100 x 0.5 = 50

Step 2: Calculate the Probability of a Vehicle Passing Through the Intersection During the Time Frame

P = (Number of vehicles passing through the intersection during the time frame) / (Total number of vehicles passing through the intersection per hour) = 50 / 100 = 0.5

Conclusion

In this analysis, we used mathematical concepts to evaluate the need for a traffic light at a busy intersection near a school. We calculated the probability of a vehicle passing through the intersection during a specific time frame and found that the probability is 0.5. This result suggests that there is a high likelihood of a vehicle passing through the intersection during the time frame, which supports the need for a traffic light at the intersection.

Recommendations

Based on the analysis, we recommend that the community activist consider the following:

Install a traffic light: The high probability of a vehicle passing through the intersection during the time frame suggests that a traffic light is necessary to ensure the safety of students and other road users.
Monitor traffic patterns: The activist should continue to monitor traffic patterns at the intersection to determine if the traffic light is effective in reducing the number of vehicles passing through the intersection during the time frame.
Adjust the traffic light timing: If the traffic light is installed, the activist should adjust the timing to ensure that the light is synchronized with the traffic flow to minimize congestion and reduce the number of vehicles passing through the intersection during the time frame.

Limitations

This analysis has several limitations, including:

Assumptions: We assumed that the traffic flow is constant and that the number of vehicles passing through the intersection per hour is 100.
Data limitations: We did not have access to real-time data on traffic patterns at the intersection, which may affect the accuracy of our results.
Simplifications: We simplified the problem by assuming that the time frame is 30 minutes, which may not accurately reflect the actual traffic patterns at the intersection.

Future Research Directions

Future research directions may include:

Collecting real-time data: Collecting real-time data on traffic patterns at the intersection to improve the accuracy of our results.
Analyzing traffic patterns: Analyzing traffic patterns at the intersection to determine if the traffic light is effective in reducing the number of vehicles passing through the intersection during the time frame.
Evaluating the impact of the traffic light: Evaluating the impact of the traffic light on traffic flow and safety at the intersection.
