  • 1. Cell Phone Use While Driving By: Amanda Letoski & Joe Dorzinsky
  • 2. Exploration: Cell Phone Use While Driving Facts <ul><li>Cell Phone use while driving is common but controversial. </li></ul><ul><li>Some jurisdictions have made the use of a cell phone while driving illegal. </li></ul><ul><li>Others have enacted laws to ban handheld mobile phone use, but allow use of a hands-free device. </li></ul>
  • 3. Exploration: Cell Phone Use While Driving Facts <ul><li>Handheld Cell Phones: 6 states (Calif., Conn., N.J., N.Y., Ore. and Wash.), D.C. and the Virgin Islands prohibit all drivers from using handheld cell phones while driving. </li></ul><ul><ul><li>All laws are primary enforcement —an officer may cite a driver for using a handheld cell phone without any other traffic offense taking place. </li></ul></ul>
  • 4. Exploration: Cell Phone Use While Driving Facts <ul><li>All Cell Phone Use: No state bans all cell phone use (handheld and hands-free) for all drivers, but many prohibit all cell phone use by certain drivers: </li></ul><ul><ul><li>School Bus Drivers: Bus drivers in 17 states and D.C. may not use a cell phone when passengers are present. </li></ul></ul>
  • 5. Exploration: Cell Phone Use While Driving Facts <ul><li>Text Messaging: 23 states, D.C. and Guam ban text messaging for all drivers. 18 states, D.C., and Guam have primary enforcement. In the other five, texting bans are secondary. </li></ul><ul><li>Crash Data Collection: Many states include a category for cell phone/electronic equipment distraction on police accident report forms. Recently proposed federal legislation would require states to collect this data in order to qualify for certain federal funding. </li></ul>
  • 6. Exploration: Cell Phone Use While Driving Facts <ul><li>The National Safety Council announced today that it estimates at least 28% of all traffic crashes – or at least 1.6 million crashes each year – are caused by drivers using cell phones and texting. NSC estimates that 1.4 million crashes each year are caused by drivers using cell phones and a minimum of 200,000 additional crashes each year are caused by drivers who are texting. </li></ul>
  • 7. Questions <ul><li>Overall Question: Is cell phone use while driving a major problem today that should be strictly enforced? </li></ul><ul><li>Research Question: Will the law on cell phone use while driving reduce accidents if it is strictly enforced? </li></ul><ul><li>Research Hypothesis: Cell phone use while driving does cause accidents. </li></ul>
  • 8. Related Factors <ul><li>Factors that contribute to accidents: </li></ul><ul><ul><li>Cell Phone Use </li></ul></ul><ul><ul><li>Road Rage </li></ul></ul><ul><ul><li>Changing the Radio </li></ul></ul><ul><ul><li>Other – weather, passengers, not paying attention </li></ul></ul><ul><li>89% agreed with the law being put into effect on cell phone use </li></ul><ul><li>71% included cell phone use as a contributer to accidents </li></ul>
  • 9. Data Collection <ul><li>Target Audience: Random sample of 38 employees from FNCB & Olympus </li></ul><ul><li>Sampling Plan: Randomly distributed the survey to business professionals </li></ul><ul><li>Summary of Respondents: Passed out 50 surveys, and received 23 back from FNCB and 15 from Olympus </li></ul><ul><li>Method of Survey: Printed out survey and handed them out </li></ul>
  • 10. Data Preparation-Survey <ul><li>Have you ever been in a car accident? </li></ul>
  • 11. Data Preparation-Survey <ul><li>What is the number one cause of accidents today? </li></ul><ul><ul><li>(a) Road Rage (b) Cell Phone Use (c) Changing the Radio (d) All the above (e) Other______ </li></ul></ul>
  • 12. Data Preparation-Survey <ul><li>Do you ever talk or text while driving? </li></ul><ul><li>How often would you say you use your cell phone while driving? </li></ul><ul><li>(a) Yes (b) no </li></ul><ul><li>(a) always (b) sometimes </li></ul><ul><li>(c) never </li></ul>
  • 13. Data Preparation-Survey <ul><li>What would you say you use your cell phone for the most? </li></ul>
  • 14. Data Preparation-Survey <ul><li>Would you say that a lot of accidents are caused by cell phone use? </li></ul>
  • 15. Data Preparation-Survey <ul><li>Do you agree with the current laws being put into effect to eliminate people using their cell phones while driving? </li></ul>
  • 16. First Hypothesis Test <ul><li>Are more than half the accidents today caused by cell phones? </li></ul><ul><ul><li>Null:  <=.50 More than half the accidents today are not caused by cell phones. </li></ul></ul><ul><ul><li>Alt:  >.50 More than half the accidents today </li></ul></ul><ul><ul><li>are caused by cell phones. </li></ul></ul>
  • 17. Are more than half the accidents today caused by cell phones? <ul><li>Reject the null hypothesis </li></ul><ul><ul><li>T- stat. > T – crit. </li></ul></ul><ul><ul><li>P value <  -level </li></ul></ul><ul><ul><li>Therefore more than half the accidents are caused by cell phone use. </li></ul></ul>
  • 18. One Sample Proportion Test
  • 19. Second Hypothesis Test <ul><li>Do more than half the people agree that enforced laws on cell phone use while driving will reduce accidents? </li></ul><ul><ul><li>Null:  <=.50 More than half the people do not agree that enforced laws on cell phones will reduce accidents. </li></ul></ul><ul><ul><li>Alt:  >.50 More than half the people do agree that enforced laws on cell phones will reduce accidents. </li></ul></ul>
  • 20. One Sample Proportion Test
  • 21. Do more than half the people agree that enforced laws on cell phone use while driving will reduce accidents? <ul><li>Reject the null hypothesis </li></ul><ul><ul><li>T- stat. > T – crit. </li></ul></ul><ul><ul><li>P value <  -level </li></ul></ul><ul><ul><li>Therefore, More than half the people do agree that enforced laws on cell phones will reduce accidents. </li></ul></ul>
  • 22. Simple Linear Regression Test <ul><li>Is there a relationship between individuals that think laws enforced on cell phone use while driving will reduce accidents and the percentage of effectiveness of the law? </li></ul><ul><li>X = individuals that think laws on cell phone use while driving will reduce accidents </li></ul><ul><li>Y = the percentage of effectiveness the law on cell phones will be if enforced </li></ul>
  • 23. Simple Linear Regression <ul><li>Null: There is not a relationship between individuals that think laws enforced on cell phone use while driving will reduce accidents and the percentage of effectiveness of the law. </li></ul><ul><li>Alt: There is a relationship between individuals that think laws enforced on cell phone use while driving will reduce accidents and the percentage of effectiveness of the law. </li></ul>
  • 24. Simple Linear Regression Model
  • 25. Simple Linear Regression <ul><li>R squared = 67.46% </li></ul><ul><li>Standard Error = 0.26 </li></ul><ul><li>Significance Level = 0.00 </li></ul><ul><li>P-value = 0.02 </li></ul><ul><li>Effective (x) = 1.18 </li></ul><ul><li>Intercept (y) = 0.18 </li></ul><ul><li>The p-value is less than alpha (0.05) </li></ul>
  • 26. Simple Linear Regression Conclusion <ul><li>We will reject the null, that proves that there is relationship between the people that agree with the law being enforced on cell phone use while driving and the % of effectiveness the law will be. </li></ul>
  • 27. Effective Line fit Plot
  • 28. Conclusions <ul><li>Based on the tests, there were obvious factors contributing to the fact that cell phone use while driving does cause accidents </li></ul><ul><li>Therefore, enforced laws on cell phone use while driving will help reduce accidents caused by cell phones </li></ul>
  • 29. Suggestions for Improving Study <ul><li>Sample different ages </li></ul><ul><li>Survey different states </li></ul><ul><li>Survey different countries </li></ul><ul><li>Ask a question concerning who had an accident due to the use of a cell phone? </li></ul><ul><li>Ask a question regarding location(city, rural, etc.) </li></ul>
