Wrong-way crashes have become a pressing issue in the U.S., with an alarming increase in fatalities over the past decade. A study by the National Transportation Safety Board (NTSB) estimates an average of 500 people die in wrong-way crashes in the U.S., and with impaired driving among a leading cause, it is crucial to address other factors such as unlicensed or suspended motorists, solo drivers, and elderly drivers.
To ensure the safe navigation of American roadways, it is essential to consider a comprehensive range of solutions that prioritize road safety.

Leveraging Technology for Enhanced Safety
Transportation authorities at the state and local levels have begun to implement alerting technologies to prevent impaired drivers from causing wrong-way crashes. These technologies include flashing signs or dynamic message signs, to warn drivers about the presence of a wrong-way driver and promote awareness that enables motorists to exit the roadway or choose a different route.
In addition, traffic management systems, such as vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication, utilize onboard networking capabilities, sensors, radar, and cameras to share real-time information about traffic slowdowns, sudden stops, and potential collisions.
Further, vehicle-to-everything (V2X) technology extends communication to pedestrians, bicyclists, traffic signals, and more, facilitating proactive measures to enhance road safety.
Improving Visibility and Detection
There are other, more advanced detection systems in use in cars, such as LIDAR, which utilizes light detection and ranging technology to aid in recognizing pedestrians that may be obscured from a driver's view.
By equipping vehicles with LIDAR, the machine can detect the presence of individuals crossing intersections, and potentially prevent accidents, and offer vulnerable road users more protection from moving vehicles.

Low-Tech Solutions for Effective Road Safety
While technology plays a crucial role, low-tech solutions have also proven effective in preventing wrong-way crashes. One such solution involves utilizing yellow collapsible traffic bollards or poles, along with alerting systems, at intersections prone to high pedestrian fatalities.
This combination helps regulate traffic flow, reducing incidents and fatalities. Lighted pedestrian push buttons, similar to elevator indicators, provide visual cues to ensure pedestrians remember to activate pedestrian crossings.
Rethinking Traffic Engineering and Roadway Design
Beyond technological and low-tech measures, traffic engineering and urban design play vital roles in enhancing road safety. The creation of dedicated cycling infrastructure separate from vehicle lanes reduces the risk to cyclists and promotes their safety. Similarly, car-free downtown spaces can protect pedestrians, cyclists, and scooter riders from the potential hazards posed by vehicles.
Roadway design can incorporate various strategies to prevent wrong-way crashes. Painting arrows on the asphalt, installing spikes or barriers, and implementing lighted and flashing reflectors directly into the road are effective visual cues that improve safety, particularly in poorly lit or competing light conditions. However, developing durable solutions that withstand constant exposure to the elements and heavy traffic remains a challenge.
Tailoring Solutions to Local Needs
The beauty of addressing this problem lies in tailoring solutions to the unique characteristics of each town or state. With individual agencies responsible for selecting the most suitable strategies for their areas, there is room for diverse high-tech and low-tech methods to safeguard drivers and pedestrians.

While the task is challenging, the pursuit of effective solutions carries immeasurable rewards. By reducing risks and implementing the right measures, substantial progress can be made towards achieving safer roads.
Did you know that there are literally tens of millions of people worldwide with hearing loss, many of whom will use some form of public transit at some point?
Thirty-five years after the passage of the Americans with Disabilities Act of 1990 (ADA), the impact of this landmark piece of civil rights legislation cannot be overstated.
Safety, on-time performance, and customer experience are critical elements in intercity bus operations. But getting them right doesn’t come down to plans or protocols alone. It comes down to execution. How well your team performs on the ground, in real time, is what defines success.
With Data Privacy Day Jan. 28, I want to spotlight a critical challenge faced by service providers in the mass transit sector: managing personal information responsibly in an era of rapidly evolving privacy regulations.
Retrieving and reviewing data and video can be a cumbersome process for fleet managers. Each system or tool provides a piece of the puzzle, but seeing the complete picture requires tedious manual synchronization.
In today’s highly connected world, cybersecurity is of utmost importance, particularly for transportation agencies overseeing transit bus systems that rely increasingly on sophisticated technologies, including the use of data analytics in traffic signal networks, to manage and operate their systems.
In the daily hustle and bustle of city life, transit buses serve as the backbone of urban transportation, allowing millions of city dwellers to get from point A to point B each day reliably.
Thirty years ago, drivers not only had to drive the bus and navigate heavy traffic, but they were also responsible for tasks like supervising passenger loading and unloading, selling tickets, and providing passengers with various kinds of information, all while sitting in an often ill-fitting workstation.
