Getting a red light ticket feels really crummy. When yellow lights ("change intervals") are set long enough, red light runners vanish.

As I review the development of the Lexus RX300, it's easy to see how this particular crossover SUV did more to fuel the sedan apocalypse than just about any other car in recent history. The RX certainly isn't the first crossover. Other pioneers certainly came first -- like the Toyota RAV4, AMC Eagle, and wagons from Subaru. The RX300 proved to Lexus, and to luxury automakers around the world, that not only was a car-based SUV possible, it would also be a hot seller.

Back in the 1950s and 60s, America used to build thousands of miles of Interstate highways each month.

Toll agencies are tearing down staffed booths (cash lanes) because they are dangerous and slow. Instead, we have to start using electronic toll collection (ETC) -- those special transponder passes. But most toll passes won't work out of state. With no toll booths, how do you pay when you are on vacation? I speak with Samuel Johnson, the chief operations officer for a southern California toll road agency (The Toll Roads - TCA), about a cool new technology which will soon make paying a toll easier than ever.

My comparison of research into the proliferation of access near a freeway interchanges (NCHRP Synthesis 332) with real-world case studies presented at Transportation Research Board (TRB) conferences. Presented at Brigham Young University (BYU) on April 5, 2018.

My award-winning student presentation to the Utah chapter of the Institute of Traffic Engineers (ITE). My presentation explores options available to replace the fuel excise tax with public-private toll roads or a vehicle-miles traveled (VMT) tax.

An in-class presentation I gave showing performance benefit from adding flyovers and braided ramps to the SR-201 and I-215 interchange in West Valley City, Utah. This is my term project for CEEn 662 (Traffic Flow Fundamentals).

A set of TV news stories I filmed and edited which show Utah restarting state highway construction projects after a temporary shut down during the recession.

A quick answer to induced demand which can happen when new roadway capacity is added, and why it is probably worth widening roads anyway.

Using VISSIM modeling software, I explored what projected future traffic growth will do to Utah's only urban cloverleaf. The verdict? Not good.
