Permanent vs. Temporary Traffic Control for Recurring Events

By Mike Spack, PE, PTOE If you’ve ever dealt with event traffic management, you know the amount of time, money and other resources that go into ensuring safe and efficient traffic conditions before, during, and after the event. But what happens when the event is recurring? At what point does it make sense to implement […]

Mini Roundabout Benefits

By Vern Swing, PE The entire team at Spack Consulting are proponents of roudabouts, and we have written extensively on the topic. But as roundabouts take hold in the US, more design ideas are coming forward on their application to improve traffic flow and improved pedestrian safety. This includes the use of mini roundabouts, which […]

Reduced Conflict Intersections

By Jacob Rojer, EIT Spack Consulting Finding a balance where both safety and traffic operations can be improved when designing an intersection can be a challenge when faced with budget constraints. I recently attended a seminar at the Minnesota Transportation Conference called “Proven Intersection Design for Reduced Conflicts”. This seminar covered alternative intersection design, best […]

Pedestrian Bridges: Safety vs. Convenience

By Max Moreland, PE, Director of Operations at Traffic Data Inc. Large roads are great for moving vehicles through an area.  However, if you are a pedestrian, getting across a wide, busy, high speed road can be daunting.  No one wants to play Frogger in real time with real consequences.  Except for maybe George Costanza. […]

What Should the Scope of a Traffic Study Be (Part 2 of 2)

By Mike Spack, PE, PTOE Part 1 in this series on scoping a traffic study dealt with the appropriate study area. This post (Part 2) discusses how far into the future we need to analyze. The Institute of Transportation Engineers (aka ITE) has developed a Recommended Practice titled Transportation Impact Analyses for Site Development.  It details the study year […]

What Should the Scope of a Traffic Study Be (Part 1 of 2)?

By Mike Spack, PE, PTOE This is a big question because the scope of the study will lead to the physical mitigation measures the developer will be responsible for. Scoping a traffic study is typically based on the size of the development and the type of location it is going into.  On a small development, the developer […]

Speed Kidney: The Ultimate in Traffic Calming Devices?

By Mike Spack, PE, PTOE I first wrote about the concept of the Speed Kidney in 2012.  Basically, it’s three speed humps that are parallel to the traveled way that are curved as a chicane per the diagram.  This doesn’t necessarily reduce the average speed very much, but they reduce the number of vehicles driving […]

Guest Post by Vernon Swing, PE, Traffic Engineering Manager at Spack Consulting. As traffic engineers, we are constantly balancing the mobility goals of the surrounding road network with the access requirements of the land use. For instance, all you need to know when considering convenience store land use is the name – convenience. Customers generally choose […]

Removing a Left Turn Lane to Provide for a Bike Lane

Bicyclist. It is a word that can incite frustration in the minds of both drivers and traffic engineers alike. But, let’s face it: bicycles are good for the environment, they are cost-effective, they are good for our collective and individual health, and the presence of cyclists within a community creates a positive image that says […]
