“…The quality of habitat surrounding the road may affect the likelihood of AVCs [15]. Other important factors relate to the road type, vehicle speed, and traffic volume [16][17][18][19]. Recent studies suggest that drivers deliberately kill animals on roads.…”

Roads are a major cause of wildlife mortality by animal-vehicle-collisions (AVCs). We monitored the patterns and frequency of AVCs on two sections of a major highway in Northern Tanzania and compared these patterns to the knowledge and perceptions of drivers who frequently use the roads. While actual field survey showed that more birds were killed by AVCs, mammals were perceived by the drivers to be the most common AVC. Drivers were indifferent to whether AVCs were a major problem on the road, and 67% strongly felt that AVCs were mainly accidental, either due to high vehicle speed or poor visibility at night. There was a negative correlation between the likelihood of a species being hit by vehicles and its average body mass. Only 35% of drivers said they had attended an educational program related to the impact of roads on wildlife. This study highlights a need for collaborative efforts between the wildlife conservation and road departments to educate road users on the importance of driving responsibly and exercising due care for wildlife and human safety. This should be coupled with effective mitigation measures to reduce the extent of AVCs.

“…For three decades now the field of road ecology has brought to light the impacts that roads and road networks have on the landscape, its wildlife, and subsequent ecosystem stability [1,2]. This paper presents seminal reviews from associating the presence of roads with the direct mortality of wildlife, hindering wildlife movement both physically and behaviorally, and the loss and degradation of habitat, all of which can have farreaching implications for regional population dynamics, species diversity, and ecosystem function [3][4][5].…”

The development and presence of roads can reduce landscape permeability, lead to habitat loss, and increase habitat fragmentation. It is these fundamental changes in landscape structure that can have both direct and indirect impacts on the conservation of species and biodiversity. In this review, I examine 215 research studies conducted between 2011 and 2015 that explore the impacts of roads and road networks on a wide range of species. I divided these studies into four main categories: 1) the direct effects of roads on wildlife, 2) the indirect effects of roads on wildlife, 3) the consequences of road networks on wildlife populations, and 4) survey design and mitigation including both innovations and evaluations. I found that the majority of studies (38%) explored the indirect effects of roads on wildlife, including displacement, fitness consequences, and road crossing ability of wildlife. Nevertheless, despite there being a pressing need to understand how existing road networks impact wildlife and how increasing road density may influence local and regional population persistence, only 10% of the studies considered the implications of road networks on wildlife. However, there is an increasing trend towards the development of predictive models that can be used for a better understanding of road network impacts, assess landscape connectivity, and devise mitigation. This review also highlighted the continued need to devise and evaluate mitigation measures so transportation authorities and conservation practitioners may be better equipped to address the ecological implications of roads and proposed road development.

Perception of the Impacts of Urban Mobility Interventions in the Niterói Oceanic Region, Brazil

et al. 2020

In a context of expansion and densification of cities, themes related to mobility and the improvement of the quality of life have aroused the interest of researchers and county managers. Using the case of the main urban mobility intervention in Niterói, the TransOceânica Road Corridor (CVT), this work aims to identify the perception of the population affected by the project in relation to the occurrence of the impacts predicted in the project planning phase, as well as to identify which of these impacts most influenced the standard of living and mobility of this population. The survey results showed that the respondents’ perception of the impacts—as the change of air quality, the change of noise levels, the alteration of the local dynamics and neighborhood disturbance—did not confirm the scenario envisaged when planning the project.
