چکیده
15. Supplementary Notes Research performed in cooperation with Texas Department of Transportation and the U.S. Department of Transportation, Federal Highway Administration. Research Project Title: Emissions Due to Construction Equipment and Traffic Delays 16. Abstract Task 6 modeled an array of possible construction work zone projects with respect to facility demand (low, medium, and high average annual daily traffic [AADT]); facility cross section (two to five lanes); number of lanes closed (one to four lanes); and work zone schedule (seven different schedules modeled). The work zone schedules included a base or typical schedule, overnight schedule, and schedules to accommodate the proposed construction bans in Dallas, Texas (banned from 06:00 to 10:00), and Houston, Texas (banned from 06:00 to 12:00), for peak and off-peak directions of flow.

Driving patterns as a contributing factor to light-duty vehicular emission in the Kumasi metropolis
Exhaust emissions contribute greatly to air pollution, the social cost of which may occur as danger to human health, attracting huge medical expenses, causing absenteeism and hence loss of productivity. These are incentives to reduce exhaust emissions to the barest minimum. Two major cities in Ghana, Accra and Kumasi, are struck by vehicular traffic jams especially during rush-hours and are gra...

Although these options look promising, they are unlikely to make a great impact in the near term. Some of them (e.g., fuel-cell vehicles) are still in their early stages of technology development and probably will need a dramatic breakthrough before they can be fully implemented. For those that are technology-ready and have started to enter the market (e.g., hybrid vehicles and alternative fuel...
