Rumble Strips, Protected Bike Lanes, and 7 Completely different Efforts to Make Roads Safer

Whereas the COVID-19 pandemic may already be throughout the rearview mirror for some, its legacy on America’s roadways continues to be acutely felt as we converse.

In line with the Nationwide Freeway Web site guests Safety Administration, the nationwide public nicely being emergency changed driving patterns drastically, with “drivers who remained on the roads engaged in extra harmful habits, along with dashing, failing to placed on seat belts, and driving beneath the have an effect on.” The sample ultimately led to a record-high number of better than 43,000 fatalities in 2021, a dramatic 10.8% improve from the sooner yr.

Whereas 2023’s virtually 41,000 freeway fatalities signify a modest decrease from 2021’s extreme, that decide stays stubbornly better than pre-pandemic ranges.

For basically probably the most half, behaviors corresponding to distracted driving and the aforementioned harmful behaviors proceed to be the precept drivers of fatalities, in accordance with TRIP, a nationwide nonprofit transportation evaluation group.

To ascertain 9 confirmed measures being adopted to boost American freeway safety—and counteract such risk components—The General consulted a Federal Highway Administration report and totally different sources to give attention to safety countermeasures that present measurable impacts.

Some, corresponding to the making use of of rumble strips, are extraordinarily simple and provide a 44% low cost in crashes between two vehicles moving into reverse directions, head-on collisions, and sideswipe accidents. Others, corresponding to roundabouts, might require a much bigger funding nonetheless promise a jaw-dropping 82% low cost in crashes.

These cameras could also be utilized in some methods, from one fixed digital digital camera concentrating on a specific location to a lot of cameras that calculate a automobile’s widespread velocity over a certain distance. The experience is environment friendly, with fixed objects leading to as a lot as a 54% low cost in crashes on foremost metropolis roads.

Rumble Strips

Newer automotive fashions in the present day are equipped with “lane departure warning methods” that sound an alarm when automobiles steer away from their lanes. Rumble strips work equally; the raised and textured strips of pavement alert drivers by the use of tactile and auditory ideas that they’ve left their lanes. Whatever the rumble strip’s low-tech composition, the bodily element of the raised freeway patterns implies that drivers can solely “flip them off” by correcting their lane positioning. The end result? A 44 to 64% low cost in head-on, flawed method, and sideswipe crashes.

Median Boundaries

There’s not a great deal of room for error in slender, high-speed roads. That’s the place median limitations can be found. Designed as each cable, concrete, or beam guardrails, limitations in the reduction of the severity of cross-lane accidents, often stopping full, head-on collisions. When utilized on rural four-lane highways, these limitations resulted in a 97% low cost in cross-media crashes. Furthermore, they supply a stage of psychological assist for drivers who’re intimidated by such fast streets.

Roundabouts

Roundabouts are one of many very important environment friendly measures for decreasing automotive crashes, boasting an 82% low cost in excessive crashes. Utilized as substitutes for standard intersections and alerts, roundabouts work by organically “transitioning guests from high-speed to low-speed environments.” Together with working with out the need for police, yearly maintenance, or guests alerts, roundabout islands moreover finish in safer roads for pedestrians and bicyclists, along with beginner or aged drivers. That’s a win-win-win in commerce for a smaller intersection.

Pedestrian Crossing Head-Start

It’s frequent for pedestrians crossing high-volume intersections to actually really feel a slight sense of trepidation and doubt sooner than crossing intersections. Pedestrian head-start alerts instantly deal with the power imbalance between automobile and pedestrians. Offering the latter a three- to seven-second head start to start out crossing sooner than automobiles see a inexperienced mild, these alerts allow pedestrians to find out themselves throughout the crosswalk and assert their right-of-way.

It’s mandatory, nonetheless, to note that islands aren’t basically environment friendly on high-speed, multilane roads, the place totally different safety measures corresponding to alerts and a reduction in lanes might finish in further fast change.

Protected Bike Lanes

Bikers who share the freeway with drivers don’t often see that favor returned. Protected bike lanes, or lanes that are separated and guarded by means of posts or totally different bodily limitations, provide cyclists a strategy to pedal in peace, with out the concern of encroaching vehicles. Nevertheless that’s not all: One study from the Faculty of Colorado Denver of 13 years of knowledge from a lot of American cities found that bike lanes act as “calming mechanisms on traffic, slowing cars and reducing fatalities.” Most prominently, lethal crash prices dropped by 61% in Seattle and 49% in San Francisco. What’s further, protected bike lanes finish in further bikers on the street, a boon for native climate activists and longer lifespans alike.

Curved Roadside Enhancements

The very fact of curved roads makes them harmful: They comprise sharp angles, in the reduction of visibility, and would possibly act in your automobile’s velocity and movement in sudden strategies. Nevertheless improved roadside designs—ranging from widened shoulders to clear zones —can remarkably improve a driver’s potential to recuperate after by chance leaving the roadway.

Similar to rumble strips, enhancements corresponding to flatter slopes and shoulders transition drivers from clear pavement to rougher terrain, signaling imminent hazard whereas giving them home to course-correct.

From web site traits, corresponding to flooring circumstances and limitations, to human components, corresponding to freeway particular person habits, elements observed in an audit come collectively to answer the question of what might very nicely be executed to take away or mitigate safety concerns. What makes the audit so incisive can also be the reality that freeway householders can’t merely neglect such findings—they’re actually mandated to arrange a correct response.
