Hello everyone, I'm embarking on a research journey to Investigate the effectiveness of shoulder rumble strips in enhancing road safety. These strips, commonly installed on the shoulders of roadways, aim to alert drivers through vibrations or noise when they veer off the road. I'm seeking advice and insights on appropriate research methodologies, procedures, and data collection techniques that could effectively measure the impact of these strips. Any suggestions or experiences shared would be immensely helpful in shaping the direction of my study. Thank you in advance for your valuable contributions!"
You can do a pre and post study. How many off the road accidents happened before the shoulder rumble strips were in place and how many occurred afterwards? Also, there should be devises that can detect how many times the rumble strips are touched by car wheels.
Good luck with this study - great question.
