Traffic is a part of life in Houston. But a new study quantifies just how much time the average Bayou City dweller spends sitting in rush hour gridlock every year—and the results are eye opening.

According to a study released this month by CoPilot, Houstonians lose nearly four days of time each year due to rush hour commuting.

The report found that rush hour extends Houstonians' commute by an extra 22 minutes per day. Annually, that totaled an additional 91.6 hours commuting due to rush hour.

This earned the Houston area (including the Woodlands and Sugar Land) a No. 8 spot on CoPilot's list of cities where commuters lose the most time to rush hour.

Evening commutes saw the highest increase in time in Houston, with the average commuter spending 14 additional minutes on roadways due to rush hour. Morning rush hour in Houston added about eight minutes to commuters' daily drives.

Houston was the only Texas city to make CoPilot's list of the top 15 cities that lost the most time to rush hour traffic. New York drivers lost the most time to rush hour, which adds about 32 minutes to daily commutes and 132 hours a year, according to the report. Los Angeles drivers lost the second-most time, followed by urban Honolulu, Miami, Baton Rouge, Louisiana; and Birmingham, Alabama.

The report found that drivers in Houston spend about eight more minutes commuting during rush hour than the average driver in the county. That totals to about 30 more hours per year than the average U.S. driver.

Commute times have been dropping nationally, reaching a low of 25.6 minutes in 2021 compared to 27.6 minutes in 2019, as more workers have transitioned to hybrid schedules or working from home, according to CoPilot

In 2020, Houston drivers even witnessed a 33 percent drop in traffic compared to in 2019, according to a study from Rice.

Still, Houston roadways are consistently ranked among the most congested in the country. Last year, a similar study found that the typical Houston driver wasted 46 hours due to traffic congestion.

Portions of the 610 West Loop are notorious for being ranked as the state's most congested roadways, and other stretches of roads are known as some of the worst bottlenecks in Texas.

New study drives home how drastically Houston traffic dropped in 2020

data-driven

Houstonians are still gauging all that they have lost during the pandemic, but one thing they gained in 2020 was time — specifically, in traffic.

Drivers who noticed less cars on the roads were witnessing a 33 percent drop in traffic in 2020, compared to 2019. That data comes courtesy of a new study by Rice University's Kinder Institute for Urban Research.

Houston traffic congestion levels dropped from 24 percent to an impressive 16 percent during the pandemic. In April, during the peak of area stay-at-home efforts, Houston's congestion level plummeted to 6 percent, the lowest of the year. February saw the highest congestion level of 2020 at 26 percent.

For some perspective, in 2019, a 30-minute took an extra 37.5 minutes than a trip during less congested conditions, the study notes.

Further illustrating the headache of 2019 commuting, local drivers lost some 119 hours of extra travel time during peak hours. The study also found that in 2019, Houston drivers lost 119 hours of extra travel time driving during peak hours.

Compare that to 2020, where local drivers lost a mere 71 hours of travel time, which is two full days less than 2019. What can one do with an extra two days? Besides the obvious Netflix and chill option, that savings offers enough time to read 3,588 pages of Marcel Proust's 4,211-page whopper, In Search of Lost Time, the study notes.

Less cars on the road was extremely beneficial for the environment, the study adds. U.S. greenhouse gas emission from energy and industry dropped more than 10 percent in 2020 — the lowest recorded level in 30 years.

Thus, the good news is that with more Houstonians working from home, commute times and the local environment benefitted. However, the study notes that with the advent of COVD vaccinations, a subsequent return to work, and with no real policy changes planned, Houston's traffic headaches could soon return.

Houston researchers report promising first in-human trial for implantable cancer therapy

cancer breakthrough

When it comes to cancer remedies, the treatment can be as challenging for the body as its cause. But what if immunotherapy could be localized? That’s precisely what a Houston team may soon make a reality.

Rice University researchers, in partnership with MD Anderson Cancer Center, recently published their findings from the first in-human trial of an implantable cancer-fighting treatment in the journal Clinical Cancer Research. The paper details testing of AVB-001, encapsulated cells engineered to release interleukin-2 (IL-2)—a naturally occurring signaling protein that boosts immunity—in the peritoneal cavities of 14 patients. The goal is to avoid the toxicity usually experienced with less targeted treatments, as well as find a solution to IL-2s’ abbreviated half-lives.

“Traditional IL-2 therapy has shown potent antitumor activity, but its clinical use has been limited by severe side effects and delivery challenges,” Omid Veiseh, director of the Rice Biotech Launch Pad, professor of bioengineering at Rice and a senior author on the study, said in a press release. “This platform allows us to localize and sustain cytokine exposure directly where tumors reside while minimizing systemic toxicity.”

Serous ovarian carcinoma is especially well-suited to the use of AVB-001 because it tends to spread throughout the abdomen. After a minimally invasive laparoscopic procedure, patients implanted with the cells were noted to tolerate the treatment well. Half of the enrolled patients’ cancer was stabilized, with several among them reporting extended signs of benefit. No maximum tolerated dose was reached and there were no life-threatening events tied to the study.

If that sounds like less-than-earth-shaking results, this is only the beginning. The capsules were implanted for about one week because IL-2 activity drops off after that. The researchers now know that further testing should include either higher levels, repeated doses, or a combination thereof, in order to create stronger advances.

The team has already made early headway on this next step. Preclinical studies in nonhuman primates were not only tolerated well, but without added toxicity, the apes had consistent pharmacological effects.

“This is a foundational step,” Veiseh explained. “We now have evidence that the platform is safe, biologically active and potentially scalable. The next phase is optimizing dosing and exploring combination therapies to unlock its full clinical potential.”

The combination would also include a checkpoint inhibitor, which might improve AVB-001’s tumor-fighting power. “What is exciting is that we are not just delivering a drug, we are programming a microenvironment,” added Dr. Amir Jazaeri, professor of gynecologic oncology at MD Anderson, member of the Rice Biotech Launch Pad’s clinical advisory board and a senior author on the study. “This opens the door to combination strategies that could amplify immune responses in ways that have not been feasible before.”
