How Wide Should a Travel Lane Be?
DTC’s own Civil Transportation instructor, Dr. Daniel Findley, was recently interviewed by WRAL TV news for an in-depth story about the impact of lane widths on safety. Although no conclusive scientific evidence is available, the results of individual studies show both increases and decreases in crashes after a lane is narrowed. Although somewhat counter-intuitive, the narrowing of a […]
Brooklyn Bridge – Still Standing Despite Everything
Designing and building the Brooklyn Bridge was anything but easy. The death of the lead engineer (and near-death of a second), foundation challenges, a mysterious illness, and the challenge of designing the tallest structures in the western hemisphere. The project was over budget and behind schedule, but over 100 years later, it’s still standing. Check […]
Exploratory Tunnel Saves Time and Money on Brenner Base Tunnel
It’s a railway tunnel connecting Austria to Italy, said to be the longest in the world. I found the exploratory tunnel to be very interesting. Having been party to a handful of tunnel projects, we are often focused on keeping the tunnel as small as possible and as short as possible, due to cost of construction […]
PE EXAM PREP TIP – Put in the Hours
There’s whole lot to learn and retain to succeed on the PE exam! Concepts you need to relearn, problem-solving skills you need to develop, references you must be familiar with. All this takes time. Start too early and your familiarity with the material will fade over time. Start too late, and the information won’t sink […]
Should You Pull In or Back In?
DTC’s Civil Transportation instructor, Dr. Daniel Findley, PE, recently published a journal article that examines the safest way to park. The analysis from this study implies that the pull-in/back-out parking maneuver is more likely to result in a collision and therefore, is associated with a higher crash risk. Further analysis of North Carolina’s parking related fatal and […]
FEATURED TESTIMONIAL – Gave Me a Lot of Self-confidence.
“The most difficult part of preparing for the Civil PE Exam was knowing the precise scope of the morning exam subjects and identifying important concepts. In that respect, the extent of each subject presented in the Dr. Tom’s class, important conceptual explanations, examples that clearly understand the concepts, and especially the various challenges gave me […]
Green Cement
A new electrochemical process for making cement has been developed by researchers at MIT. Although the process isn’t ready to scale yet, the potential to reduce greenhouse emissions from this critical building material is immense. Cement is currently responsible for 8% of global greenhouse gas emissions because the typical process for making Portland cement requires […]
New Trains Run on Hydrogen Fuel Cells – Only Waste Is H2O
I saw recently that a company called Alstom has created working trains that run on hydrogen and produce only water and steam emissions. Right now, the company’s trains have started a pilot program in Germany with two trains currently running. They plan to add 14 more by December 2021 and have announced expansion plans to […]
FEATURED TESTIMONIAL – Have Courage, You Can Pass the PE!
“I was in near disbelief to read “Exam Result: Pass.” Six months of study and it PAID OFF! It had been 12 years since the last time I was in a college classroom and 8 of those years were not doing engineering work. (5 years in seminary and 3 years running a small engine repair […]
