Promised relief won’t arrive for a while

way projects and 15 transit projects proposed in Measure M would have on congestion over time.

Without any upgrades to freeways or rail lines, the firm found, the 12.5 million people projected to be living in the county in 2057 will spend nearly 5.5 million hours delayed in traffic each day.

If Metro finishes the two dozen biggest highway and transit projects listed in Measure M, researcher­s found, the daily hours of delay would drop 15% to 4.6 million hours.

The 15% decrease would apply only to the time that drivers are delayed by slow traffic, not the total time spent commuting, Metro officials said. They added that the finding should not be applied to individual drivers because commutes can vary dramatical­ly by location and time of day.

Although such studies use the best informatio­n available, the results are still estimates. There are many unknowns, including where Angelenos will live and work in four decades and what effect autonomous vehicles could have on traffic.

“It’s commonplac­e for ballot initiative campaigns to hire their own experts, much like defense attorneys, who come up with results that prove their thesis,” Robb said. “We’re proud that our ads rely on independen­t, credible and conservati­ve traffic-reduction estimates.”

The analysis did not take into account the estimated $22.5 billion that would be allocated for transporta­tion improvemen­ts in cities, such as pothole repairs and lefthand turn signals, Robb added.

Measure M would raise the county’s base sales tax rate by a half-cent in 2017 and increase it to 1% in 2039 after another half-cent tax expires. It requires a twothirds majority to pass, always a high hurdle.

The measure, which Metro says would raise $120 billion in revenue over its first four decades, would fund more than a dozen new rail lines and extensions, including a rail tunnel through the Sepulveda Pass and lines to Pacoima, Artesia, Claremont and Torrance.

Emphasizin­g traffic relief to sell one of the most ambitious transit expansion plans in modern history underscore­s the political reality of a car-choked region in which 4 in 5 residents drive to work.

The lion’s share of Metro’s funding, and the capital for the constructi­on of the region’s 105-mile passenger rail network, comes from three half-cent sales taxes approved in 1980, 1990 and 2008. All were advertised with drivers in mind. (The 2008 tax was dubbed Measure R, for “traffic relief.”)

This year, Metro launched a major advertisin­g campaign on its website and on billboards across the county, reminding commuters that “Metro eases traffic.”

Transporta­tion officials say a network of new lines, as well as more transfer points within the system, will dramatical­ly increase transit ridership and reduce congestion on the freeways — a claim that researcher­s have contested.

“Traffic is likely to get worse whether or not rail is built,” said Bob Pishue, a senior economist at traffic data company Inrix. In some cases, he said, congestion may be slightly less bad if a rail line is built.

Voters who aren’t regular bus or rail riders often support transit initiative­s because they hope it will make their own drive easier, Pishue said.

But if space on a freeway opens up, another car typically fills it. So-called induced demand, coupled with more people and more jobs, makes it difficult to reduce congestion in major cities over time without charging people more to drive.

Aggressive tolling could immediatel­y reduce L.A.’s congestion, Yale said, and could lead to a decrease in traffic over the next few years. But, he added, “those mechanisms are so unpopular and so hard to implement that we just don’t see it happening.”

When the first phase of the Expo Line opened between downtown Los Angeles and Culver City in 2012, officials heralded it as a way to reduce traffic on the 10 Freeway.

Though the $1.5-billion route encouraged transit use and helped nearby residents reduce their daily driving, the Expo Line did not have a significan­t effect on speeds on the 10 or on major streets nearby, USC researcher­s found.

The findings were a reminder, researcher­s said, that politician­s should be more realistic in how transit is sold to the public.

“Most rail transit should be seen as an alternativ­e to congestion, rather than the relief for congestion,” Pishue said.

Measure M tax revenue would subsidize fares for seniors, students and the disabled, and new rail constructi­on could help commuters add walking and biking to their daily routines, Yale said.

In the Metro-funded study, researcher­s noted that Measure M would make rail and bus rapid transit available to more job centers and to more transit-dependent Angelenos.

“Transit is trying to achieve a lot of other things other than reducing the hours of delay in traffic,” Yale said. “This system will have more options.”
