“…Thermal infra-red images confirmed that the albedo significantly contributes to the urban microclimate (Baldinelli and Bonafoni, 2015). Comparison of air temperature above reflective concrete, porous asphalt, porous concrete and conventional asphalt pavements (Coseo and Larsen, 2015) shows the difference between these materials in terms of heating an urban landscape.…”

In the present century, there has been increasing global pressure on governments to implement policies to incentivize reductions in CO 2 emissions based on the devastating effects of global climate change. Researchers generally have established the fact that the automobile sector generates more than 50% of the atmospheric carbon concentration. It has also become obvious that FCC-Abuja Nigeria is merely a replica of Lagos transport-wise in all ramifications. The Abuja master plan as of 1979 specifically recommended the development of mass transport by light-rail when the city's inhabitants are about 1.6 and 3.1 million for airport. The non-implementation of the light rail in the city has aggravated the flood of vehicular traffic that generates a lot of Green House Gas that in turn swells up the city's ambient temperature. This research therefore used the handheld outdoor thermometer to measure the traffic corridors in Abuja in relation to the WHO and FEPA tolerance threshold standard. This is compared with the modern electric rail that is environmentally friendly, and the result reveals that the present transport system in the city negates the global crusade for Green Mobility. It is therefore recommended that the Federal Government of Nigeria should as a matter of urgency cease from her lip-service to the global SDGs and fully implements the overdue Abuja light rail that will positively woo the other cities of the federation.

“…The average mean temperature from May to September is 25.9 • C (1961-1990) [50]. Since the 1995 Chicago heat wave, when up to 800 perished due to the heat [51,52], the City of Chicago has worked with researchers and sought policies to document the urban heat island drivers and address heat vulnerability [4,40,53,54]. Thus, Chicago has been a leader in bridging research and policy on urban-induced heating.…”

Urban heat islands (UHI) increase summer temperatures and can threaten human well-being during extreme heat events. Since urbanization plays a key role in UHI development, accurate quantification of land cover types is critical to their identification. This study examines how quantifying land cover types using both two- and three-dimensional approaches to land cover quantification affects an UHI model’s explanatory power. Two-dimensional approaches treat tree canopies as a land cover, whereas three-dimensional approaches document the land cover areas obscured under tree canopies. We compare how accurately the two approaches explain elevated air temperatures in Chicago, Illinois. Our results show on average 14.1% of impervious surface areas went undocumented using a two-dimensional approach. The most common concealed impervious surfaces were sidewalks, driveways, and parking lots (+6.2%), followed by roads (+6.1%). Yet, the three-dimensional approach did not improve the explanatory power of a UHI model substantially. At 2 a.m., the adjusted R2 increased from 0.64 for a two-dimensional analysis to 0.68 for a three-dimensional analysis. We found that the less time consuming two-dimensional quantification of land covers was sufficient to predict neighborhood UHIs. As climate change exacerbates UHI, more cities will map urban hotspots and this research increases our understanding of alternative approaches.

“…The different thermal characteristics of these materials are recognized by Doulos et al [31] as a strategic challenge in cooling urban spaces. Comparison of air temperature above reflective concrete, porous asphalt, porous concrete, porous concrete pavers pavement, and conventional asphalt pavements [32] shows the difference between these materials in terms of heating an urban landscape. Thermal infrared images confirmed that the albedo significantly contributes to the urban microclimate [33]: If compared to bituminous pavements, the concrete ones have lower surface temperature, as confirmed by several researches (e.g., References [34,35]).…”

Transport infrastructures are lifelines: They provide transportation of people and goods, in ordinary and emergency conditions, thus they should be resilient to increasing natural disasters and hazards. This work presents several technologies adopted around the world to adapt and defend transport infrastructures against effects of climate change. Three main climate change challenges have been examined: Air temperatures variability and extremization, water bombs, and sea level rise. For each type of the examined phenomena the paper presents engineered, and architectural solutions adopted to prevent disasters and protect citizens. In all cases, the countermeasures require deeper prediction of weather and climate conditions during the service life of the infrastructure. The experience gained supports the fact that strategies adopted or designed to contrast the effects of climate change on transport infrastructures pursue three main goals: To prevent the damages, protect the structures, and monitor and communicate to users the current conditions. Indeed, the analyses show that the ongoing climate change will increase its impact on transport infrastructures, exposing people to unacceptable risks. Therefore, prevention and protection measures shall be adopted more frequently in the interest of collective safety.
