Glatting Jackson is the internationally-reknowned transportation and walkability consultant whose design guides the new street network plan in the White Flint Sector Plan. Glatting Jackson also designed the “Transitway Option” for Rockville Pike, placing a dedicated transitway in the median of the renovated Pike.
Now Glatting Jackson has issued a “white paper” discussing various concerns about transportation and mobility issues in White Flint, including those suggested by the October 5 letter from County Executive Isiah Leggett.
For example, Glatting Jackson notes that “speed and capacity are not synonymous,” meaning that Rockville Pike can carry significant amounts of traffic without a high speed limit. Similarly, the White Paper offers three examples of congestion measurements from Colorado and Florida to show that the current tests proposed by opponents of the current White Flint Plan draft (which focus principally on how fast cars move through intersections) are not the only, or even the best ways to measure mobility efficiency.
