Annotated Summary



Annotated summary:

Lee, J. H., Noh, K. S., Kim, J. M., & Choi, J. S. (2013). The Effects of Pavement Markings on High-risk Drivers' Speeds. International Journal of Highway Engineering, 15(1), 127-134. Retrieved from https://doi.org/10.7855/IJHE.2013.15.1.127



This research article studies the effects of pavement markings on drivers who are negligent on traffic regulations and partake in dangerous road activities. The study focuses on varying pavement markings used internationally that have been known to reduce driving speeds.

The various road markings introduced in the study include “Peripheral transverse lines, transverse lines and dragon teeth”. Lee’s team mentions that these markings showed a significant decrease in average driving velocities after implementation (as cited in Katz (2004))

The research article performed a study with two stages. The first stage was a questionnaire to determine a driver’s negligence towards traffic laws and engagement in dangerous road activities.

The second stage of the study was tested their driving conduct on roads, with and without pavement markings. The study showed that Dragons Teeth were the most effective in decreasing average driving velocity, for drivers who are likely to disobey traffic regulations or engage in dangerous road activities. On the other hand, peripheral transverse lines showed to be the most effective in reducing average velocity for drivers who obey traffic regulations and do not partake in dangerous road activities.

The study concluded that dragon’s teeth and peripheral transverse lines were most effective in reducing speed. It suggests that additional research is needed to provide more data on the success of the pavement markings, as drivers may be too comfortable to pavement markings and develop a negligence towards it in the long run. Additionally, the authors also indicated that “colour contrasts” can be looked into in a future study.

This research article provided a good insight on the effects of dragon’s teeth markings on motorists, as proposed in our research project. Furthermore, the indication that using colour to captivate motorists is a measure that our research project is looking towards, in addition to implementing traffic calming markings.

Commented on Jamie's, Thoufeek's and Tha Zin's blog.

    Hi Syahmi very interesting article and definitely related to your project. One think that interest me is that the markings are there to visually "force" the driver to slow down and is a cheap alternative to prevent accidents. If i understand correctly, the marking works by visually disorienting the driver. Could this effect cause undesirable results to someone very sensitive to visual stimulation?

    And also there seems to be an odd sentence in paragraph 4 "The second stage of the study was tested their driving conduct on roads, with and without pavement markings." Do check it out! Good job!

      Hi Brien,

      Thank you for your comment. I would say that the markings are there to influence the driver, instead of force. And also, the effect would work similar to any road markings you currently see on the road. Any markings implemented on the road will be similar to the markings you see on the road now, and will not be cluttered to prevent confusion.

      And yes, I believe there was a missing word there. I will correct it. Thanks!

      Regards,
      Muhammad Syahmi

    Hi Syahmi,

    Your annotated summary is well written and informative. It is also strongly linked to your research project.

    Just some things to note:

    1. "This research article studies the effects of pavement markings on drivers who are negligent on traffic regulations and partake in dangerous road activities."

    I believe that the phrase should be "drivers who are negligent ABOUT traffic regulations", according to https://www.merriam-webster.com/dictionary/negligent

    2. "(as cited in Katz (2004))"

    Based of APA, I believe the citation should be " (as cited in Katz, 2004).", according to https://apastyle.apa.org/learn/faqs/cite-another-source (remember to add a full stop behind your citation.

    3. "reducing average velocity for drivers" and "decreasing average driving velocity, for drivers"

    I believe "of drivers" would be a better phrase to use as you are referring to the decrease in speed that the drivers are driving at.

    4. "most effective in reducing speed"

    You may want to include what "speed" is being reduced. Although with context it is understandable that you are referring to the speed that drivers are driving at. As a standalone, the sentence is vague about what "speed" is being reduced.

    Otherwise, good job!

    Regards,
    Jamie

      Dear Jamie,

      Thank you for the comment. There were certain flaws in my language and grammar that can certainly be improved. I will take your constructive comments seriously as I edit my annotated summary.

      Again, thank you for the "short" comment!

      Regards,
      Muhammad Syahmi

Learning Portfolio: Critical Reflection (Final)

Before the start of this course, I had a particular perception of my communication skills. While I am proactive, I have learned to work with others in peer reviews or technical report discussions, I have listened to others occasionally and became open to the ideas of others. When pitching an idea for the scope of our technical report, I listened to the ideas of others and in doing so, EyesOnStripes was founded. While it was difficult to be a less proactive team member, I found opportunities where my strengths could be contributed which included report-writing as well as studying literature reviews. Throughout this module, I have accepted the views of others, and my use of language has also improved as I realised that most mistakes surrounding language use are due to common speaking habits. In writing, I have consulted with APA formats more often, and have used paraphrasing to shorten my writing while providing a more concise point to the reader. In week 8, we were tasked to dra...

Learning Portfolio: Letter of transmittal (Final)

Letter of transmittal EyesOnStripes Mr Tan Tee Nee Director Traffic Design & Management Land Transport Authority 1 Hampshire Road Singapore 219428 Re: Proposed implementation of improvised traffic road calming markings (TrCM) at slip road zebra crossing Following a request for a proposal on developing innovative solutions for an engineering problem, a proposal report has been consolidated to implement traffic calming road markings on slip road zebra crossings to improve overall road safety. The proposal comprises the identified problem, which stems from the lack of clarity of road markings at slip road zebra crossings, and how the proposed solution seeks to address the matter of high accident rates at slip road zebra crossings. The benefits and challenges of the proposed solution are presented with great detail in the proposal. The proposed solution intends to improvise on existing traffic calming road markings, such as the “dragon teeth” road markings and yellow checkered markings...
