I had been an industrial electrician for 20 years and decided to take a new job on the utility side of electricity. Found this course online and took it as a fast learning crash course to help me get a good understanding of the basics of a lot of the substation components and relay theory. Very good material and study guide. I highly recommend it.

Fundamental Skills and Knowledge of Cost Engineering

Iowa State University’s Fundamental Skills and Knowledge of Cost Engineering course was very informative. It was presented in a very holistic manner that fostered learning and understanding. The information I learned will be utilized within my occupation because I function within the estimating field, and participate in other projects where the material is usable. I intend to utilize the skills learned to help restructure and develop some policies and other guidelines for our estimating department. After this course, I am now able to join and appreciate the estimating and project management sides within a project, and utilize the appropriate terminologies for various aspects for each stage of a project. I intend on becoming certified as a cost professional which will in turn benefit my organization. This course has put me one step closer to my goal.

A well structured course that would form a good basis for AACE certifications and domain knowledge.

usRAP Data-Driven Safety Analysis and Planning

It was an enjoyable online course with well structured modules, clear presentation slides and videos and good preparation materials for downloading and reading. The quizzes and tests are designed to help better understanding of the subject matter. I intend to use the knowledge and information gained from this course to apply on developing a consistent well thought through road safety program and projects going forward at my workplace. The benefits from this course will enable more confidence for me to deliver those works.
Highly recommended for those who have a passion in road safety.

I found the us-RAP data coding course very useful to get more familiar with iRAP Road Safety Assessment method. Lots of examples helped me to be able to differentiate between similar choices you may select when assessing a real road and after taking this course I’m more confident about select a road attribute including the type of roadside land-use, pavement condition, etc. I’ve used iRAP and RSA methods to assess the safety of roads but I think iRAP is better because after passing courses like this one road engineers are able to assess a road leading to more reliable results. RSA needs highly experienced experts to make sure the assessment results are reliable based on reviewed checklists. Data-driven safety Analysis course is an amazing one that put stress on the importance of evidence-based interventions and mentions the characteristics of high-quality data needed for high-quality analysis to achieve desired goals.

I did the course on usRAP Data driven safety analysis and planning as I am actively searching on online courses which are helpful in professional development and I can actually use that knowledge. I found this course interesting because of its proactive nature and use of ViDA software which proactively suggest what should be done to reduce accident and hence fatalities by the use of photographs and maps. We are in the phase of constructing roads (!) hence some way behind making them safer but this course has given me insights into how to make our completed roads more safer if related organization seek professional ideas about doing something

Thank you so much for providing this unparalleled course, ” usRAP Data-Driven Safety Analysis and Planning”. I am conducting some research on road safety on a route-level scale in Iran as a developing country. This fantastic course broadened my horizon in this field of study, especially in collecting the built environment data.

This course will surely be beneficial to our company as we plan for the ISO 39001 certification as one of the pillars on road safety is having safe road and a proactive approached on addressing road crashes.
