The role of Street condition and forms on the amount of carbon emissions released from vehicles
In the last two decades, the percentage volume of carbon emissions has increased from 280 to more than 380 parts per million in the atmosphere, the problem is that it is still increasing daily in which it caused many environmental hazards that has been seen the last couple of years. The end of this century, It is expected that the uncontrolled amount of emissions emitted to the atmosphere will increase the surface temperature of plant earth by 3.4oC. Worldwide, the percentage of carbon emissions in the atmosphere and its effect on air quality has been the main concern of scientist and researchers in the past decade. Egypt is one of the biggest emitters that surfer from atmospheric pollution, almost 24% of the atmosphere pollutants in Egypt is from the transportation sector due to the heavy use of fossil fuels. Reducing the roads carbon emissions through streets design and form is the main scope of this research. This research intends to control the amount of carbon emission released in air by vehicles through controlling vehicles speed and motion, which affected by the street design and form. The presented research analysis the relation between carbon emissions and streets condition and forms, through measuring the amount of CO2 and CO emission produced in one of the Egyptian roads from different types of vehicles in road with three different conditions. El-Shuhada Street has been chosen to be the study area of this research. The researchers used Testo 315-3 to measure the Carbon emissions in the street and to identify the relation between CO2 emission and street condition and form. The results revealed that straight route with vehicle speeds ranged between 80 to 100 kn/h produces less carbon emissions then straight routes with street bumps and vehicle speed ranged between 26 to 19 km/h. Moreover, curved routes emitted more emission than straight routes.
