Paving the way for green roads

The University of New Hampshire's Recycled Materials Resource Management Center is developing criteria for green roads, which could lead to sweeping reforms in the construction industry. The center's research focuses on reducing the environmental impacts of road-building, such as carbon footprint and stormwater runoff generation.

Forest elephants at risk from the illegal ivory trade

A new study warns that forest elephants are facing intense poaching pressure due to the illegal ivory trade. The researchers found only 1,900 elephants remaining in Salonga National Park, with the probability of encountering them increasing with distance from roads.

Elephant highways of death

A new study reveals that forest elephants are being pushed into remote depths of national parks due to heavy poaching for ivory near roadways. Protected areas, however, are critical to elephant survival, with some areas experiencing increased abundance despite road access.

New highways carry pathogens and social change in Ecuador

A new study by the University of Michigan found that the construction of new highways in rural Ecuador is linked to higher rates of diarrheal diseases and a breakdown of traditional social structures. The roads, which connect previously isolated villages, bring new people and bacteria, leading to increased infection rates.

A road is more than a road

The University of Vermont is introducing a new systems education project to reform its engineering curriculum, emphasizing the connection between traffic and social, environmental, and economic factors. The project aims to equip students with skills to analyze complex problems and provide solutions that consider multiple perspectives.

Car manufacturers acting in the interest of profits rather than safety in poor countries

A recent study published in Injury Prevention calls for increased vigilance on car manufacturers' commitment to road safety initiatives. The research analyzed word frequency analysis of road safety documents from the Global Road Safety Partnership and found that commercial interests often conflict with evidence-based recommendations.

New easy-read road signs based on PSU research

A new typeface called Clearview has been approved by the Federal Highway Administration (FHWA) for use on public roads in the US and Canada. The Clearview typeface offers a 20% improvement in legibility and recognition with the same size sign as currently used, reducing driver confusion and increasing safety.

'Aggregate and the Environment'

The book provides detailed explanations of procedures used to manage and minimize environmental impacts of aggregate mining, processing, and transportation. It also highlights successful reclamation projects that convert mined areas into beneficial uses such as recreation areas and natural habitats.

Jays and cars don't mix

Researchers found that Florida scrub-jays nesting along roadsides die at a higher rate than those on non-road territories, with up to half of new breeders dying in their first two years. The roadside death rate is particularly high for young fledglings and newly arrived breeders.

Roads affect 20% of U.S. land

A study by Harvard University's Richard Forman estimates that US roads directly affect the ecology of nearly 20% of U.S. land, blocking animal migrations and spreading non-native species. Traffic noise also reduces bird populations, making it harder for them to communicate with their young.

Tire Chip Research Focuses On Fire And Ice

Researchers are finding ways to repurpose old tires by using them in the construction of roads and retaining walls. Tire chips have been used successfully in three major new bridges in southern Maine and sections of three Maine roads, showing significantly less frost heave than conventionally built sections.
