This report analyzes factors contributing to bus operations safety incidents at TriMet, the transit provider for the Portland Oregon metropolitan region. The analysis focuses on 4,631 collision and non-collision incidents that occurred between 2006 and 2009. Empirical analysis of these incidents draws on a wide array of operator-level data recovered by transit ITS technologies in combination with information from TriMet's human resources, scheduling, and customer relations databases. Incident frequencies are estimated in relation to operators' demographic characteristics, employment status, assigned work characteristics, service delivery and performance indicators, temporal factors, and customer information. Apart from identifying factors that are empirically related to the frequency of safety incidents, the findings offer insights into operations policies and practices that hold promise for improving safety.
The incidence of bus crashes in the US have been trending upwards, with accident, injury and fatality rates increasing 171%, 37.8%, and 5. responsive action events and customer complaints about unsafe bus operation. These findings make some contributions to the understanding of the factors that are empirically related to the frequency of safety incidents as well as offer insights into operation practices and policies that hold promise for reducing bus safety incidents.ii Acknowledgment
This study assessed the influence of quality improvement practices on creative governance success in Tier four public hospitals in Kenya. The study adopted a descriptive correlation research design. The target population was 200 composed of Administrative officers and Mid-level employees from each hospital. A census survey of 200 respondents was used. A Questionnaire yielding an acceptable reliability coefficient 0.7 and response rate of 157 respondents was attained during data collection. The background information was analyzed using descriptive statistics such as frequencies and percentages. The hypothesis testing was done using linear regression analysis. Quality Improvement (QI) practices assessed entailed: Establishment of dedicated quality improvement teams, holding of regular quality improvement meetings, establishing QI procedures/models, evidence of QI data collection and analysis and, monitoring to measure change. Overall, there is implementation of QI practices to some extent in the Tier four hospitals in Kenya. Correlation analysis between QI practices and creative governance indicated a strong positive significant relationship (r= 0.672 p= 0.00,). Creative governance was measured by innovative ideas/products, creative designs of processes, learning new skills, attainment of organization goals, motivated staff and satisfied clients. On testing the study hypothesis, results showed that quality improvement practices influenced creative governance (β= 0.55; p=0.000) but to mere 55% in the case of these selected public hospitals. The study results therefore inform hospital managers on the need to pay more attention to quality improvement practices so that the hospitals may reap the benefits of creative governance which then leads to superior delivery of services.
