in the past, forest road network designing was mainly done for its main goals-management and exploitation. this study was performed to pay attention for multilateral goals of forest roads, especially its role in forest villages’ development, in estakhr-posht of neka (6 villages) in series 2, section 6 of neka-zalem rood forest management plan. at first, constructed forest roads and suggested ro...

China was quite behind the United States, Germany, and some other countries when it comes to permitting testing of self-driving cars on public roads. However, this is no longer case as now leads way by commercial operations vehicles.

Efforts to mitigate road effects are now common in new highway construction projects. For effective mitigation of road effects it is important to identify the species whose populations are reduced by roads, so that mitigation efforts can be tailored to those species. We conducted a meta-analysis using data from 75 studies that quantified the relationship between roads and/or traffic and populat...

Road traffic accidents account for approximately 3000 deaths on a daily basis, and 50 million injuries and 1.2 million deaths each year. In low-income and middle income countries, road traffic accidents account for 85% of deaths and 90% of annual disability. Casualties of this magnitude are a serious problem throughout the world and create a significant impact on society. In addition, neurologi...

In this study an attempt has been made to assess the potential of land as a municipal financing tool in four Indian cities, to enable better public service delivery and attainment of the MDGs. The institutional arrangements for land use are fragmented in India’s cities between the urban development authorities, which are state agencies, and the cities. To determine whether or not transfer of re...

We have developed a lane change aid system (LCAS), which detects vehicles behind in adjacent lanes with multi-line CCD sensors and informs the driver of vehicle location with a head-up display (HUD). Instead of processing camera images directly, a multi-line CCD sensor contains the pairs of line CCDs and measures two-dimensional distance distribution by comparing the brightness on line CCDs. To...

The effects of crime are diverse and complex, ranging from psychological and physical trauma faced by victims to the negative impacts on the economy and external image of a country. From a criminological perspective, the commission of a crime is caused by a combination of factors such as situational circumstances, social and individual-level factors. In this paper, a new 3D real-time simulation...

Prioritizing public investments requires information on relative returns that are difficult to derive from disparate evaluation studies. This paper presents a ‘hybrid’ approach that combines ex post evaluation data with an economy-wide model for experimenting ex ante with alternative investment portfolios within a consistent, structural framework. The approach is used to evaluate rural investme...

Situation awareness for vehicular safety and autonomy functions includes knowledge of the drivable area. This area is normally constrained between stationary road-side objects as guard-rails, curbs, ditches and vegetation. We consider these as extended objects modeled by polynomials along the road, and propose an algorithm to track each polynomial based on noisy range and bearing detections, ty...
