Using cameras on transit buses to monitor traffic conditions
Newswise — COLUMBUS, Ohio – Researchers have proposed a novel method for counting and tracking vehicles on public roads, a development that could enhance current traffic systems and help travelers get to their destinations faster.
Using the cameras already installed on campus buses at The Ohio State University, researchers demonstrated that they could automatically and accurately measure counts of vehicles on urban roadways, could detect objects in the road, and could distinguish parked vehicles from those that are moving.
In previous studies, Ohio State researchers found that using these mobile cameras provides much better spatial and temporal coverage than relying on sparsely and often temporarily placed sensors that don’t provide a view of many streets and roads in a city.
“If we collect and process more comprehensive high-resolution spatial information about what’s happening on the roads, then planners could better understand changes in demand, effectively improving efficiency in the broader transportation system,” said Keith Redmill, lead author of the study and a research associate professor of electrical and computer engineering at Ohio State.
Whereas researchers previously used human observers to manually identify the vehicles in the videos, this study, published in the journal Sensors, automates the process using AI.
According to co-authors of the study Mark McCord and Rabi Mishalani, both professors of civil, environmental and geodetic engineering at Ohio State, their team chose to utilize the traffic cameras on the Campus Area Bus Service partly because Ohio State’s large, interconnected campus resembles a small city and their relationship with CABS operators gave them ready access to the collected videos.
“Sharing access to our bus cameras for traffic monitoring is a great example of how university operations can support research and learning,” said Tom Holman, Ohio State’s director of Transportation and Traffic Management. “We are happy to share existing resources that can generate helpful data for long-term traffic planning purposes on campus and beyond.”
But what sets this study apart from similar traffic-related studies is that it utilizes available resources at no extra cost: bus cameras that have already been installed for other safety and security purposes. This allows it to be easily integrated into how other cities manage their traffic monitoring, said Mishalani.
“If we can measure traffic in a way that is as good or better than what is conventionally done with fixed sensors, then we will have created something incredibly useful extremely cheaply,” he said. “Our goal is to start building a system that could do this without much manual intervention because if you want to collect this information over lots of potential vehicles and lots of time, it’s worth fully automating that process.”
The system works by utilizing a state-of-the-art 2D deep learning model called YOLOv4 to automatically detect and track objects. The program is also uniquely adept at recognizing multiple objects in a single image frame, said Redmill.
While still a long way from total implementation, the study suggests the system’s results bear promise for the future of intelligent traffic surveillance. For example, besides counting vehicles, their algorithm is also able to project real-world bird’s-eye-view coordinates of the road network by taking advantage of streams of images, GNSS measurements, and regional information from 2D maps. It’s so precise, the system was also able to detect if the bus veered off from its planned route – and then report it to a map database that logs detailed information about the roadways, said Redmill, who is also a member of Ohio State’s Control and Intelligent Transportations Research Lab (CITR).
With widespread deployment and integration of their proposed approach, the vast collection and complete automation of processing of this data over time would allow for more effective planning, designing and operation of roadways to mitigate heavy traffic across the country.
As for the benefits the public might see, such advancements in traffic surveillance could mean reduced travel times and greater travel choices when trying to get from point A to point B.
“Transportation planners, engineers and operators make vital decisions about the future of our roadways, so when designing transportation systems to work over the next 30 to 50 years, it’s imperative that we give them data that allows them to improve the efficiency of the system and the level of service provided to travelers,” said Mishalani.
The research was supported by the United States Department of Transportation’s Mobility21 University Transportation Center program. Other co-authors are Ekim Yurtsever and Benjamin Coifman, both of Ohio State.

Embracing Armchair Urbanism: Understanding the Built Environment
Armchair urbanism: Exploring urban areas, their design, and the interaction between people and the built environment. #Urbanism #ArmchairUrbanist
In today’s rapidly urbanizing world, the study of urbanism has become increasingly relevant. As an armchair urbanist, I find myself captivated by the intricate dynamics between inhabitants and their built environment. This term refers to individuals who take a keen interest in urban areas, their design, and the way people interact with them. In this blog post, we will delve into the concept of armchair urbanism, exploring its significance and the factors driving urbanization worldwide.
Understanding Urbanism:
Urbanism encompasses various disciplines, including urban planning and urban sociology, which aim to comprehend the complexities of urban life. Urban areas, such as cities, towns, conurbations, and suburbs, are the products of urbanization, marking a contrast to rural environments. Modern urban planning has evolved from the ancient urban revolution, shaping human civilization and leaving a lasting impact on the environment.
The Global Shift:
The growth of urban areas has been remarkable over the past century. In 1950, 764 million people lived in urban areas globally, while by 2014, this number had skyrocketed to 3.9 billion. The surge in urban population is a result of both overall population growth and an increased percentage of people residing in urban areas. In 2009, urban dwellers outnumbered their rural counterparts, marking a pivotal moment in human history. Projections indicate that the urban population will comprise 68% of the global population by 2050, with substantial growth expected in Africa and Asia.
Drivers of Urbanization:
Urbanization is fueled by various factors, including economic opportunities, improved infrastructure, and access to better services. Countries such as Argentina and Japan boast urbanization rates exceeding 90%, while Australia, Brazil, Canada, Mexico, and the United States fall within the 80-90% range. These nations demonstrate how urbanization has reshaped societies and economies, creating interconnected metropolitan areas that extend beyond city boundaries.
The Armchair Perspective:
As an armchair urbanist, I find inspiration in observing, analyzing, and discussing the built environment from a distance. It involves exploring the evolution of urban spaces, understanding architectural styles, and contemplating the social, economic, and environmental implications of urban development. While not actively involved in urban planning or research, armchair urbanists contribute to the broader conversation and raise awareness about the importance of sustainable and inclusive cities.
Armchair urbanism provides an avenue for individuals to engage with the world of urbanism from a personal perspective. It allows us to appreciate the complexities of urban areas, their growth, and their impact on societies and the environment. By embracing this role, armchair urbanists contribute to shaping a future where cities are designed to meet the needs of their inhabitants while fostering sustainability and inclusivity. As our world continues to urbanize at an unprecedented rate, armchair urbanism becomes an increasingly valuable lens through which we can understand and appreciate the ever-changing urban landscape.

Putting Jobs First: California High-Speed Rail Crosses 13,000 Construction Jobs Milestone
In a significant milestone for the nation’s first high-speed rail project, the California High-Speed Rail Authority (Authority) announced that it has successfully created over 13,000 construction jobs since 2015. This accomplishment not only signifies progress for the ambitious high-speed rail system but also highlights the positive impact it has had on the local Californian workforce.
Central Valley Takes the Lead:
With over 70 percent of these jobs going to residents of California’s Central Valley, the project has played a vital role in providing employment opportunities for individuals in the region. It is worth acknowledging the efforts of nearly 1,400 workers dispatched each day to various high-speed rail construction sites. These jobs have injected economic vitality and growth into communities across the Central Valley.
Regional Breakdown:
- Fresno County: 4,222 jobs
- Kern County: 2,538 jobs
- Tulare County: 1,282 jobs
- Madera County: 580 jobs
- Kings County: 462 jobs
- Merced County: 189 jobs
- Remaining California Counties: 3,387 jobs
- Out-of-State: 369 jobs
A Decade of Strong Partnerships:
The Authority has had a longstanding partnership with the California State Building Trades, which has facilitated the creation of thousands of good-paying union jobs. Notably, during the past five years alone, over 10,000 construction positions have been generated through these collaborative efforts. Moreover, a significant focus has been placed on directing employment opportunities towards individuals from disadvantaged communities, further promoting inclusivity and economic upliftment.
California Jobs First Council:
To bolster job creation even further and ensure economic prosperity for all Californians, the California Jobs First Council was established. This council aims to align economic resources, expedite job creation, and enhance opportunities throughout the state.

What is California High-Speed Rail?
The California High-Speed Rail (CAHSR) is a state-funded project led by the California High-Speed Rail Authority. Currently under construction, Phase 1 is planned to cover 494 miles from San Francisco to Los Angeles, passing through the Central Valley. There are plans for Phase 2, which would extend the system to Sacramento and San Diego, totaling 776 miles. Authorized by a 2008 ballot, this ambitious project aims to connect major urban areas, significantly reducing travel times. The goal for Phase 1 is to achieve a travel time of 2 hours and 40 minutes between San Francisco and Los Angeles, a vast improvement from the existing Amtrak service, which takes around nine hours.
Construction of Phase 1 began in the Central Valley back in 2015. The project is being built in sections due to limited funding. The state aims to complete a 171-mile (275 km) long Initial Operating Segment (IOS) connecting Merced and Bakersfield by 2024. The IOS is expected to begin its revenue service as a self-contained high-speed rail system between 2030-2033, at an estimated cost of $28–35 billion. CAHSR trains running along this section would be the fastest in the Americas, with a top speed of 220 mph (350 km/h).
Between January 2015 and December 2023, a whopping amount of $11.2 billion was spent on the IOS project, which includes 119 miles (192 km) currently under construction, alongside upgrades to the existing rail lines in the San Francisco Bay Area and Greater Los Angeles. The plan is that Phase 1 will share tracks with conventional passenger trains. However, the Authority has not yet secured funding to connect the Central Valley section with either the Bay Area or Los Angeles, which involves crossing several major mountain passes. As of 2024, it is estimated that Phase 1 will cost a total of $106.2 billion.n.
Supporters of the California High-Speed Rail project emphasize the potential benefits it offers, including the reduction of air traffic and highway congestion, decreased pollution and greenhouse gas emissions, and the promotion of economic growth by connecting inland regions to coastal cities. However, opponents argue that the project is too expensive and advocate for directing funds to other transportation or infrastructure initiatives. The choice of route and the decision to initiate construction in the Central Valley, rather than more densely populated areas, have been points of contention. The project has encountered notable challenges such as delays and cost overruns due to management issues, legal disputes, and a lack of complete funding commitment.
