Some say Level of Service (LOS) is Dead. Its Not.
PRISM Engineering. Analyzing and optimizing traffic flows through signal timing and lane utilization at the intersection level.
All drivers want at least LOS C or better conditions.
Anything less is an aggravation in driving.
California's High Speed Rail Woes. A train now, who's future build is a question mark. At an estimated cost of over $100,000,000,000 (that's $100 BILLION), this improvement did not match the need/demand. There are 1,857 miles of interstate freeways in CA today (I-5, I-8, I-40, I-80 etc), if reconstructed all over today using new materials, would cost much less at $6,000,000 per mile for a 6 lane rolling hills freeway, and so the total cost would be $6M x 1,857 miles = $11,140,000,000. Let that sink in. $11 Billion.
The proposed HSR would cost 9 times more than just building all BRAND NEW interstate freeways from the foundation up, throughout all of California. All new freeways, 10's of thousands of jobs, for 1/10 the cost of the HSR project.

PRISM Engineering highlights HSR progress to date, in Central California on HSR location.
Fully Autonomous Vehicles on Redesigned Roadways with Grade Separations between Pedestrians and Vehicles is the Future Safety Solution that has been Elusive.
1.25 MILLION PEOPLE die each year in vehicle related accidents. 1.25 Million, each year! This default status quo is not acceptable. AV is the obvious near-term solution.
PRISM Engineering discusses why AUTONOMOUS VEHICLES are the answer.
