New studies sees potential for reductions with fundamental shifts in transportation policies
The heat-trapping pollution spewing from trucks, cars, busses, ships and airplanes adds up to a hefty 23 percent of global greenhouse gas emissions — and they are projected to double by 2050.
But with a concerted effort, the transportation sector could cut that amount by half within the next 35 years. Needed is more fuel efficiency and more public transit in cities, along with a large-scale shift to electric cars, according to a new study that took a close look at emissions from transportation.

Can new laws help ease I-70 congestion?
Lack of incentives, limited public awareness has stunted the wide adoption of collision avoidance technology
FRISCO — Federal safety officials blasted the U.S. auto industry in a new report for failing to make progress on using life-saving collision avoidance systems in new cars.
The National Transportation Safety Board report says rear-end crashes kill about 1,700 people every year and injure half a million more. More than 80 percent of those deaths and injuries might have been mitigated had the vehicles been equipped with a collision avoidance system.
“You don’t pay extra for your seatbelt,” said NTSB Chairman Christopher A. Hart. “And you shouldn’t have to pay extra for technology that can help prevent a collision altogether.” Continue reading

New traffic pollution data screams out for better transit planning and improved emissions control technology for motor vehicles
FRISCO — Pollution from auto exhaust can quickly build to dangerous levels at stoplights, where drivers are exposed to about 25 percent of their total exposure during a typical commute.
More and more research is proving that the nanoparticles from exhaust contribute significantly to respiratory and heart disease, so University of Surrey scientists decided to study the exposure. Drivers spend just 2 percent of their journey time passing through traffic intersections managed by lights, this short duration contributes to about 25 percent of total exposure to these harmful particles.
Signalized traffic intersections were found to be high pollution hot-spots due to the frequent changes in driving conditions. With drivers decelerating and stopping at lights, then revving up to move quickly when lights go green, peak particle concentration was found to be 29 times higher than that during free flowing traffic conditions.

FRISCO — U.S. airlines aren’t making much progress in reducing greenhouse gas emissions, according to a new report from the International Council on Clean Transportation. Despite some improvement by individual airlines, the analysis showed there was no net improvement in the fuel efficiency of U.S. domestic operations from 2012 to 2013.
The nonprofit organization also calculated that two of the most fuel efficient carriers — Alaska and Spirit — had the highest operating profit margins in 2013. Meanwhile less-efficient carriers like Allegiant made profits while using old, polluting and less efficient aircraft. The study findings contradict airline industry arguments that fuel costs automatically push airlines to maximize efficiency. Continue reading

Clearing the roads in Frisco, Colorado.
A little bit of salt on your french fries is fine; a lot of salt on the road kills trees and fish
FRISCO — Highway engineers and scientists know that that massive use of chemical road de-icers has significant environmental impacts. Salt and the various derivatives used to keep roadways open kills trees and degrades water quality.
Just last year, the EPA found salt building up in groundwater near highways in the eastern U.S. Across the country, the U.S. spends $2.3 billion each year on the removal of highway snow and ice plus another $5 billion to mitigate the hidden costs associated with the process.
The hidden costs include long-term impacts of salt, sand and chemical deicers on the natural environment and road infrastructure as well as short-term impacts on semi-trailer trucks and other vehicles from rust and corrosion. Continue reading

Installation of fire suppression system in the Eisenhower-Johnson Tunnels could spur discussion on hazmat routing
Hazmat routes are ubiquitous along Colorado’s major highways.
By Bob Berwyn
FRISCO — With $25 million in funding secured for a long-sought fire suppression system in the I-70 Eisenhower-Johnson Tunnels, a debate over hazmat routing through Summit County could heat up again. In a first step, CDOT will start a process to update the 1980s-era rules for the tunnel, potentially opening the door to a petition process that could result in changes to the hazmat route.
Currently, gasoline tankers and nearly all other hazardous materials are routed via U.S. Highway 6 over windy Loveland Pass, where tankers frequently roll over and spill fuel. Most truckers would prefer to haul their flammable, toxic and explosive materials through the tunnel and down I-70 to save time and money, but local emergency responders aren’t sure if the change makes sense from a public safety standpoint.
“This is going to require some very careful evaluation,” said Summit County emergency services director Joel Cochran, acknowledging that there have already been some behind-the-scenes discussions among some stakeholders. Continue reading

Peak-period shoulder toll lane to ease eastbound congestion; CDOT hopes to finish the work by 2015
By Bob Berwyn
FRISCO — As soon as they finish with the current I-70 construction around the Twin Tunnel segment, Colorado Department of Transportation engineers will set their sights on another project aimed at easing eastbound traffic congestion on the busy Colorado east-west interstate.
A nine-mile section of peak-period shoulder lanes from Empire Junction to the Twin Tunnels could loosen up Sunday afternoon traffic jams by providing three lanes from the junction all the way back to Denver, said CDOT mountain corridor manager Jim Bemelen.
The estimated cost for improving the shoulders is about $30 million, and funding for the project has been approved as part of a statewide $560 million slate of upgrades under the Responsible Acceleration of Maintenance and Partnerships (RAMP) program, announced by Gov. John Hickenlooper and CDOT director Don Hunt this week. Continue reading
