M.P.H., Faculty of Health, University of the Witwatersrand, 2011 / In South Africa, injury remains one of the major causes of death. International data also suggests that intentional and unintentional deaths are on the increase globally with highest increases noted in the middle and low income economies. The National Injury Mortality Surveillance System (NIMSS) which captures only 40% of all annual nonnatural deaths revealed that 27% of these deaths occurring mainly in adults and children are motor vehicle related. 58% of these are pedestrians. The rationale of this study stems from the findings for the National Injury Mortality Surveillance System (NIMSS) of 2002, which indicated a high pedestrian mortality. This study is a descriptive cross sectional analysis of pedestrian related mortality data from an existing NIMSS database. Continuous variables were summarised using means and standard deviation while categorical variable were summarised using proportions. Summary data were presented in graphs and tables. This was conducted using a statistical programme STATA10. Between 2001 and 2005, motor vehicle transport related deaths comprised 11.32% of all recorded un-natural deaths in Soweto with pedestrians accounting for 50% of deaths. The Pedestrian mortality comprised the dominant proportion of all motor vehicle related mortality from 2001to2005 (compared to drivers, passengers and unspecified road user categories). From the results of the study, it was shown that most pedestrian deaths occurred in the black population group, followed by coloureds. It also confirmed that the majority of pedestrian deaths were of the male gender group. With regards to time and day of death, it concluded that pedestrian deaths occurred in between 1800h and 2400h, mainly over weekends, whereas by age group, age group, most pedestrian fatalities were adolescents and young adults followed by children. When it came to access to emergency medical care, the study showed that the majority of dead pedestrians were never attended to by Emergency Medical personnel. Blood alcohol concentrations were raised in a high percentage of those fatalities in whom it was possible to measure such concentrations, suggesting that alcohol played a significant role in pedestrian deaths. A number of preventative and advocacy initiatives are recommended, with emphasis on broad based stake holder participation, education, engineering, as well as targeted interventions that address specific issues that were identified as major contributing factors to the observed increased vulnerability in those specific categories of pedestrians.

Bermudagrass is the predominant turfgrass used for athletic fields in the southern United States. Numerous bermudagrass cultivars are utilized for sports field use. Two frequent variations in management among facilities include mowing and nitrogen fertility regimes. Research is needed to determine the influence of bermudagrass cultivar, mowing regime, and nitrogen fertility on traffic tolerance. Research conducted at Texas A&M Univeristy studied the traffic tolerance of Tifsport, GN-1, Princess, and NuMex Sahara bermudagrasses. These grasses were mowed once weekly at 3.80 cm and three times weekly at 1.90 cm and fertilized with 146, 292, 585, or 1171 kg ha-1 yr-1. Digital images were taken before and after simulated traffic to provide a quantitative value for percent coverage. Images were analyzed for percent green canopy coverage using Sigma Scan Pro. The number of green pixels was divided by the total image pixels a yielding a percent coverage value. Shoot density, visual quality, tissue water content, and tissue dry mass values were taken monthly. Percent tissue nitrogen was taken for three months. Analysis of digital images revealed variability in traffic injury tolerance between varieties. Tifsport, GN-1, and Princess maintained higher percent coverage than NuMex Sahara. GN-1, Princess, and Tifsport were able to tolerate traffic but did not maintain acceptable quality. Lower and more frequent mowing increased shoot density and visual quality for all grasses. Increased nitrogen fertility levelsincreased tissue succulence and tissue dry mass but did not affect the traffic tolerance of any variety. Increasing nitrogen fertility above 585 kg ha-1 yr-1 showed no benefit other than increasing visual color. This research provides a guide for managers to make informed decisions on cultivar selection and management practices under traffic conditions.
