Community Safety Zones

Community Safety Zones are typically located near schools, senior communities, busy neighborhood streets, transit stops and areas with a history of serious crashes. Inside a zone, the Polk County Roads and Drainage Division may use tools like lower speed limits, brighter crosswalks, flashing beacons, speed feedback signs or targeted enforcement. Zones are chosen using real crash data and community feedback, and the improvements protect everyone, drivers included.

Speed and street design decide whether a crash becomes a life-changing event. A pedestrian struck at 20 mph has a strong chance of surviving. At 40 mph, the risk of death rises sharply. At 60 mph, survival is highly unlikely. Slower speeds give drivers more time to react and make it far more likely that a person walking or biking survives. These zones ensure safer and more walkable neighborhoods.

School Safety Zones

Children are among the most vulnerable road users. Their height, reaction time and ability to judge vehicle speed put them at greater risk. School Safety Zones are designed to add extra protection to keep students, families and faculty safe. Around schools, bus stops and student walking and biking routes, the county may use lower speed limits, flashing school beacons, high-visibility crosswalks, crossing guards, speed feedback signs and improved sidewalks to create a safer environment during arrival and dismissal times.

These zones exist to protect children, not to penalize drivers. Speed limits are based on state law and crash data, beacons are timed to match school schedules and community feedback helps identify unsafe routes.

Senior Safety Zones

Reaction times slow, mobility changes and visibility challenges increase with age. That makes older adults more vulnerable as pedestrians, transit riders and drivers. In 2021, adults 65 and older made up 18% of the U.S. pedestrian deaths but only 15% of the total population.

Senior Safety Zones help in areas including near senior living communities, care facilities, medical centers, and transit stops. These zones have reduced speed limits, brighter lighting, longer pedestrian crossing times, curb ramps and clearer signage.

These zones support Vision Zero by focusing on safety improvements for older adults, who are more likely to be seriously injured as pedestrians, and help them stay active, connected and independent.

Traffic Signals and Pedestrian Crossings

Traffic signals and pedestrian crossings are how Polk County manages the way people move through intersections, whether they drive, walk, bike or use a mobility device. Serious crashes are more likely to occur at intersections due to multiple travel paths crossing at the same point.

Safety tools include standard traffic signals, pedestrian crossing signals, countdown timers, high-visibility crosswalks, push-button crossings, pedestrian-only phases and Leading Pedestrian Intervals (LPI), which give people walking a 3 to 7 second head start before cars move. LPI’s can cut pedestrian crashes at intersections by 13% and better crosswalk visibility can reduce pedestrian injury crashes by around 40%. Also remember that drivers must stop for people in marked crosswalks, even when turning.

These signals and crossings are placed based on traffic volumes, crash history and community needs. They are designed to protect everyone by reducing confusions and improving visibility.

Accessible Pedestrian Signals (APS)

Crossing a busy street is hard for anyone who cannot rely on visual cues alone. Accessible Pedestrian Signals (APS) are devices that help people who are blind, have low vision or have other disabilities cross the street safely. They use audible tones, spoken messages like “walk sign is on,” surfaces that vibrate when the walk signal begins, tactile arrows pointing toward the crosswalk and push buttons placed within easy reach. The audible message begins only when the walk signal is active, and vibrating surfaces help people who are deaf-blind.

APS devices are installed to support people with disabilities and locations are chosen based on community needs, crash history and accessibility standards. Equitable access and safety go hand in hand.

Red Light Cameras

Red light cameras are automated safety devices placed at intersections to record vehicles that run a red light. When a driver enters the intersection after the signal has turned red, the camera captures a photo of the vehicle, a short video clip of the violation and the license plate number. The goal is not surveillance, but rather preventing dangerous crashes caused by drivers who fail to stop at red lights.

Running red lights is one of the leading causes of severe intersection crashes. These collisions are often high‑speed, side‑impact crashes that result in serious injuries or deaths. Red light cameras help reduce these risks by encouraging drivers to stop instead of speeding through yellow or red lights, reducing dangerous T‑bone and angle crashes, making intersections more predictable for everyone, supporting law enforcement with consistent, unbiased enforcement and improving safety for pedestrians, cyclists and turning vehicles. For Polk County, red light cameras are a proven Vision Zero tool that helps prevent the most severe types of intersection crashes.

Cameras only activate when a vehicle enters the intersection after the light turns red, and violations are reviewed by trained staff before a citation is issued. The purpose is safety, not revenue. Cameras reduce severe crashes, especially where speeding and red‑light running are common. Signs are posted to let drivers know cameras are in use, and these systems help protect children, seniors and families who walk or drive through busy intersections. Red light cameras make intersections safer by encouraging responsible driving.

LED Blank‑Out Signs

LED blank out signs are electronic traffic signs that stay dark until they need to display a specific safety message. When activated, the sign lights up with a bright, easy to see symbol or instruction. These instructions include “No turn on red,” “No left turn,” “Yield to pedestrians,” or “Do not enter.” Because the sign is blank when not in use, drivers are less likely to overlook it when it turns on. When it is on, the message will be clear, noticeable, and when it is lit, the instruction is mandatory not optional.

Many serious crashes happen when drivers miss or ignore traditional signs, especially at busy intersections or during turning movements. LED blank‑out signs improve safety by making critical warnings highly visible in all lighting conditions, reducing confusion at complex intersections, helping drivers understand when turning is temporarily unsafe, protecting pedestrians during crossing phases and supporting enforcement by making the rule unmistakable. For Polk County, these signs are a smart Vision Zero tool because they reduce high‑risk turning conflicts and improve compliance with safety rules.

These signs are used at intersections with a history of crashes or near schools, senior areas and busy pedestrian routes. The goal is safety, not enforcement or penalties. LED blank‑out signs make intersections more predictable and safer for everyone.
