SAN DIEGO (KGTV) — Caltrans is starting a yearlong pilot program in San Diego to reduce wrong-way driving.The agency has installed markings at 30 locations that include red arrows and "DO NOT ENTER" written across the pavement that are only legible when driving in the wrong direction onto freeway ramps.The markings will stay up until the end of the year, according to Caltrans.The agency says that a previous three-year pilot program helped reduce wrong-way driving by 44% in San Diego. The program utilized special reflectors, sensors, and illuminated signs in early 2018.Now, those specialized reflectors have been installed on hundreds of miles of highways, according to Caltrans."The number of wrong-way drivers decreased significantly during the initial pilot program," said Caltrans Director Toks Omishakin. "The addition of these markings, along with what we have learned thus far, will go a long way as we continue to study ways to deter wrong-way drivers."While wrong-way crashes only account for less than 1% of all crashes on California's highways, they are often among the deadliest, Caltrans said."We are constantly looking for ways to improve safety on the transportation system," said Caltrans (San Diego area) District 11 Director Gustavo Dallarda. "If the testing of this new product is successful, it could provide a new tool to reduce wrong-way driving." 1383

SAN DIEGO (KGTV) — As states continue to count votes, one thing is clear: the pre-election polls were off again.Pollsters underestimated support for President Donald Trump by a wider margin than they did in 2016, prompting a number of theories about what went wrong and why changes adopted after the 2016 election proved ineffective.Heading into Election Day 2020, candidate Joe Biden led Trump nationally by an average of 8.4%, according to FiveThirtyEight’s polling average. We won’t know the final margin until all the votes are counted, but it looks like Trump’s support was underestimated by about 3.5%.That’s wider than the national popular vote miss in 2016, when the polls underestimated Trump’s support by 1.1%.“Polling emerged from 2016 with a black eye. This is fair to say a second black eye in 2020,” said Jay Leve of polling firm SurveyUSA.Leve said the industry thought it had corrected its 2016 mistakes. Polling in the 2018 midterms was very accurate.In 2020, pollsters made sure to weigh for education level and include enough non-college-educated white voters to try to capture a representative sample of the electorate.But state polls show it didn’t work. In Ohio, there was a nearly 8-point miss. In Wisconsin, there was a nearly 10-point miss. In Florida, the polls missed by 5 points and incorrectly showed Biden in the lead.“While pollsters attempted to correct for the mistakes that they made in 2016, President Trump was busy hammering home a narrative that, number one, the media is the enemy of the people. And number two, polls are fake polls,” Leve said.Leve thinks that skepticism and distrust caused Trump supporters to ignore pollsters at a higher rate, causing them to be underrepresented in samples.San Diego State political scientist Dr. Stephen Goggin says there are other theories as well.“Between mail-in balloting, the pandemic, between all the early voting and all the confusion it creates, it’s possible some of that played a role in creating the error we saw this time,” he said.Goggin said the pandemic may have made the models used to predict voter turnout less accurate this cycle. Many surveys heading into the election showed an unusual trend: Biden was polling better among so-called “likely voters” than among registered voters overall. Typically Republicans hold an edge among likely voters, Nate Cohn of the New York Times noted.There’s also some early data suggesting once the pandemic hit, Democrats started responding to surveys more frequently, something that could have shifted the poll numbers.There may have also been issues surveying certain demographic groups. Pre-election polls showed Biden chipping away at Trump’s lead with seniors compared to 2016, but Biden actually did worse than Clinton with that demographic in certain key states. Trump’s support among Hispanic voters in Florida also surprised pollsters. If exit polling data shows that trend continued in other states, it might explain about one-quarter of this year’s polling error, according to the New York Times.“Many of these errors are fixable when they find out what went wrong and you can still get high-quality samples,” Goggin said.Pollsters are planning to do detailed autopsies on the election once they have final turnout data and results by precinct. Polling firms will eventually post detailed data from their results to the Roper Center for more finely tuned analysis.ABC 10News used SurveyUSA this election cycle to poll 11 state and local races. The final polls accurately predicted the winner in all 11 races, although the margins weren’t perfect.The ABC 10News/Union-Tribune scientific polls actually overestimated Trump’s support in California by about 4 points, relative to vote totals as of November 12. 3757

SAN DIEGO (KGTV) -- Caltrans presented five renderings of possible suicide barriers for the San Diego-Coronado Bridge.More than 400 people have killed themselves by jumping from the bridge since it was opened in 1969, making it the second deadliest suicide bridge in the nation behind San Francisco’s Golden Gate Bridge.The possible suicide barriers include a large net underneath the bridge similar to the one to be put on the Golden Gate Bridge, three types of fencing, or 18-inch spikes on top of the existing barriers.Caltrans said one design will be chosen in Spring 2018.They said it will take several years to build the barrier because they need to have environmental impact studies done and get funding for it.  752

  

SAN DIEGO (KGTV) -- California’s superintendent of schools announced a new plan to study the role and impact of police on school campuses.During a Wednesday morning virtual press conference, State Superintendent of Public Instruction Tony Thurmond said he wants to speed up research in examining how police at schools affect students.“We need to set clear standards that police officer should never be dean of students or disciplinarian for student behavior,” Thurmond said.Schools may still need police on campus to respond to situations such as active shooters or bomb threats, Thurmond said, but he was clear that officers should never treat students like criminals.In the wake of protests over the death of George Floyd in Minneapolis and as people across the U.S. call for systemic change in the role police play in all of our lives, Thurmond is organizing a task force to study police presence at schools.“We should have more restorative justice programs, focus on de-escalation, programs that focus on intervention that can be done by those who have the ability to use peacemaking skills to reduce violence,” Thurmond said.San Diego County is no stranger to police-related controversy on local school campuses.In 2016, a fight at Lincoln High School ended with school police using Tasers and pepper spray on students. One officer and four students were hospitalized, and two students were arrested.In 2018, a campus police officer slammed a student at Helix High School onto the ground. That student later filed a lawsuit over the incident.Now, a Change.org petition is calling for the San Diego Unified School District to close its district police department, saying, “Policing schools creates a toxic school climate that attenuates the school-to-prison pipeline and is not necessary to cultivating school safety.”As of Wednesday, the petition has just over 1,800 signatures.Federal data shows a slightly disproportionate amount of arrests of minority students within San Diego Unified School District. Data shows 66 percent of arrests are of Black or Hispanic students, even though they only make up 56 percent of the school population.Thurmond said he wants to look into that issue specifically.“To make sure that any police officer who is on campus is someone who wants to be on campus, who has chosen to be there, not just been assigned. And there will be training for them in implicit bias, de-escalation and understanding youth development,” Thurmond said.SD Unified officials have not responded to the petition or Thurmond’s comments, but on the district website, officials said having officers on campus allows them to build relationships with students, teachers, and staff, and better serve the school community. 2737

  

SAN DIEGO (KGTV) -- Authorities are investigating after an inmate died at the George Bailey Detention Facility. According to the San Diego County Sheriff’s Department, deputies were notified that an inmate identified as 63-year-old Dennis Lee Curry needed medical help inside his cell on May 11. Deputies say when they arrived, Curry complained of pain to his head and chest, but had no visible injuries. Curry was taken to a local hospital where his condition worsened and he was placed on life support before he died on the morning of May 13. Following an autopsy, it was discovered that Curry died of natural causes. The Sheriff’s Department’s homicide unit was called in to investigate, as they do with all in-custody deaths. Curry was in custody for outstanding warrants related to prior DUI and drug-related charges, according to the department. 860
