This study assesses changes in mobility behaviour in the City of Barcelona due the COVID‐19pandemic and its impact on air pollution and GHG emissions. Urban transport is an important sourceof global greenhouse gas (GHG) emissions. Improving urban mobility patterns is therefore crucial formitigating climate change. This study combines quantitative survey data and official governmentdata with in‐depth interviews with public administration officials of the City. Data illustrates thatBarcelona has experienced an unprecedented reduction in mobility during the lockdown (a 90%drop) and mobility remained at comparatively low levels throughout the year 2020. Most remarkableis the decrease in the use of public transport in 2020 compared to pre‐pandemic levels, whereas roadtraffic has decreased to a lesser extent and cycling surged at times to levels up to 60% higher thanpre‐pandemic levels. These changes in mobility have led to a radical and historic reduction in airpollution, with NO2 and PM10 concentration complying with WHO guidelines in 2020. Reductions inGHG emissions for Barcelona’s transport sector are estimated at almost 250.000 t CO2eq in 2020 (7%of the City’s overall annual emissions). The study derives policy implications aimed at achieving along‐term shift towards climate‐friendlier, low‐emission transport in Barcelona, namely how torecover lost demand in public transport and seize the opportunity that the crisis brings for reform byfurther reducing road traffic and establishing a 'cycling culture' in Barcelona, as already achieved inother European cities.

Transit Performance

The need for an efficient public mass transportation system in the context of developing countries can well be overemphasized since a majority of the urban population continues to be either captive walkers or users of the public transport facility. In Addis Ababa, inadequacy of public transit and improper traffic management issues are dominant problems. Evidence indicates that solutions related to traffic congestion and accidents are still left behind the city. However, it is expected that the recent project interventions and initiatives will enhance the capability of the public transit to deliver effective and sustainable transportation. This chapter evaluates the public transit performance, the initiatives towards terminals, and the future models for implementation. It concludes that an integrated public mass transit system is vital to a sustainable future public transport in developing cities in general and in Addis Ababa in particular. Recommendations are forwarded in the chapter.

The Time Domain

For some time residents of big cities have been encouraged to change their means of transport, that is, to swap passenger cars for public transport vehicles. This is meant to help to reduce the problems associated with heavy traffic and air pollution. The authors of the article decided to check if such a change is also beneficial from the point of view of comfort and health of a person who uses public transport. For this purpose values of vibration acceleration and sound pressure level to which Cracow’s commuters are exposed to have been analyzed, depending on the type of vehicle they choose. In this respect measurements have been carried out for passenger cars, buses and trams. Two vehicle models of each type, significantly different from each other (old and new) have been selected for the tests. The measurements during a few trips in each type of vehicle on a predetermined route have been conducted. This article presents a comparison of measured values of vibroacoustic parameters in the time domain. It attempts to assess vibration and noise parameters, taking into account their impact on the health and comfort of the traveler.

Ecological Aspects

The article presents ecological aspects in road public transport. There were described main sources of smog and the percentage of air pollution (produced by road vehicles) was also showed. Details connected with the Euro emission standards (concerning buses used in public transport) were characterized and types of bus engines were also described. At the end of the article conception of current buses exchange was contained.

SMOG is a form of horrible air pollution that has recently been declared as a public health emergency in Southeast Asia. This article will talk about the drawback of smog pollution and its outcomes on human health. Smog has become the most important issue for Pakistan, from some past years. Since 2011, nearly all areas of Pakistan especially Lahore has been repeatedly affected by smog. In Many previous types of research, the focus is on Smog and, its source, alarm systems, and safeguard, when a risky Environmental event like smog, the conclusion may be riskier than the event itself will cause if people take irrational actions due to lack of relevant awareness. So, examine people's attitudes and a reaction to smog is theoretically and realistically meaningful. Recent projects of coal as a source of energy, high rates of outpouring from unmonitored industries, a large number of automobiles on roads, play a major role in trends of deforestation to construct new roads and recently the burning of crops leftovers has added fuel to the fire. Vehicles increase by 9% compared to the last five years due to a lack of public transport systems. Pakistan, India, and Bangladesh emit the most hydrocarbons in their fuel emissions compared to SAARC (South Asian Association for Regional Cooperation) countries. As a result of these problems, Pakistan is facing its relatives, losses and various dangerous human diseases.
