Can Carpool Convenience Convert the Solo Driver?

For the relative few who can use them, the looming ramps connecting carpool lanes to carpool lanes may seem like a slice of driving heaven: congestion-free travel virtually guaranteed at some of the busiest interchanges in the country.

In Orange County, home to the most extensive carpool lane system per freeway miles in the state, however, residents say they are less likely to change commuting habits than in other counties where the benefits are fewer.

Even so, county officials have pursued an aggressive carpool lane plan that includes five of the six freeway-to-freeway carpool lane connectors in the state. The five Orange County ramps will cost more than $300 million to complete. The only other such ramps in operation or planned carry car-poolers between the Century and Harbor freeways in Los Angeles.

Orange County’s connector boom comes at a time when carpool lanes are rapidly losing favor elsewhere in the country and few jurisdictions are building the costly connectors. Perhaps more significantly, the connectors completed in Orange County have performed far short of expectations. The one linking the Santa Ana and Costa Mesa freeway carpool lanes is capable of carrying 1,800 cars per hour and remaining free-flowing, but has had peak traffic of 950 cars an hour southbound and 740 cars northbound.

Many transportation experts, even some who support high-occupancy vehicle, or HOV systems, question whether connectors are worth the hefty price tag.

“It’s a gold-plated solution that benefits only a small fraction of the commuting population,” said Kenneth Orski, a transportation consultant based in Washington, D.C. “It’s great for those relatively few commuters who can use them. But from a commuting point of view it’s a waste of money.”

Concern about the cost effectiveness of the ramps led Southern California Assn. of Government officials to ask Orange County planners to reconsider including carpool lane connectors on plans to expand the Garden Grove Freeway. With connectors, SCAG planner Hasan Ikhrata said the cost of the project would double from $200 million to $400 million.

But SCAG and other regional planning groups have remained fierce proponents of an expanded carpool lane system in Southern California as a way to battle gridlock in the face of a projected population boom. By 2015, Caltrans plans to double the number of carpool lanes on freeways--from 305 miles to 680 miles--in Los Angeles, Orange, Riverside, San Bernardino and Ventura counties.

Some Statistics Support Policy

Much of the work will be funded with federal dollars earmarked for pollution-reducing transportation solutions. In support of the policy, officials cite statistics that show California is the only state in the nation not to see a decline in the number of carpools in recent years.

“We aren’t forming as many new carpools as we would like, but the carpool lanes throughout most of the system are well utilized and moving a lot of people every day, “ said Mark Pisano, SCAG’s executive director.

What role carpool lane connectors could play in enticing more riders has yet to seen, Pisano said. The ramps, he said, may go a long way toward making carpools a much faster way for commuters to get to work, the one factor proven to persuade people to change habits.

Without the connectors, moving from one freeway’s diamond lanes to another’s becomes a purgatory of sorts, forcing car-poolers to cross congested lanes of regular freeway traffic, slowing down their trip.

“The longer the distance people can go on carpool lanes the more likely they will change their travel behavior to use them,” said Cheryl Collier, who manages SCAG’s Ride Share program. “Having a seamless commute would make a difference.”

Foes of carpool lanes say the multimillion-dollar flyovers are another example of throwing good money after bad.

“They’d be better off pouring the money down a rat hole,” said Jim Thomas, a Marin County-based activist for the National Motorists Assn., a grass-roots group that backed the abolition of the national speed limit in 1996 and is working to demolish carpool lanes nationwide. “Carpool lanes don’t work, have never worked and aren’t going to work because they build these connectors.”

Orange County-based Drivers for Highway Safety has been fighting the lanes since the mid-1980s and remains one of the most active anti-carpool groups in the nation. Wayne King, the group’s leader, said the connectors are just the latest example that officials are going to go ahead with carpool lanes no matter what.

“It’s not forward thinking to ignore the compelling evidence after 12 years of carpool lane operation,” King said. “They don’t get people out of their cars to share rides with someone else.”

But county transportation officials argue that carpool lane opponents ignore the reality of funding modern road building and improvements. Monte Ward, director of special projects at the Orange County Transportation Authority, said that carpool lanes have been a pragmatic way to fight congestion on Orange County roads.

According to the authority’s figures, at least $95 million in federal funds targeted specifically for carpool lane construction has been used in the county since the mid-1980s.

Work on the last of the currently planned connectors--at the San Diego Freeway-Costa Mesa Freeway interchange--gets underway in November and will last about four years at a cost of about $150 million. Between now and then, carpool connectors are scheduled to open at the Santa Ana and Riverside freeways, the convergence of the Santa Ana, Garden Grove and Orange freeways, and the Orange and Riverside freeways.

County’s Plans Could Change

Still county officials say the ultimate fate of the carpool lane system is not written in stone. Already there is some precedent for reversing course. Last year, New Jersey gave up on carpool lanes on two congested freeways, becoming the first state to do so without having to reimburse hundreds of millions of dollars to the federal government.

Ward said there may be plenty of room to fine-tune the system once it is finished and county officials can judge how well-used the lanes are. When the system is complete, about 85% of Orange County’s 187 miles of freeway will have carpool lanes.

“Once we have it in place I think there will be room to talk about how to maximize the effectiveness of the system,” Ward said.

“There has been talk about considering a HOT (high-occupancy toll) lane system, charging single motorists a toll to use the lanes. Could we use the lanes for trucks only? For some sort of transit system? I’m not sure what the system will look like 20 years from now.”
