“…Many transportation agencies divide pavement performance measurements into two categories: pavement roughness (e.g., IRI) and pavement distress (e.g., Pavement Distress Index). The Pavement Quality Index (PQI), which integrates both roughness and distress, is used to represent the overall pavement health conditions [35][36][37][38]. Although those sophisticated techniques and data analytics can establish the pavement condition accurately, their applications are quite limited by the data collection.…”

Monitoring pavement conditions is critical to pavement management and maintenance. Traditionally, pavement distress is mainly identified via accelerometers, videos, and laser scanning. However, the geographical coverage and temporal frequency are constrained by the limited amount of equipment and labor, which sometimes may delay road maintenance. By contrast, crowdsourced data, in a manner of crowdsensing, can provide real-time and valuable roadway information for extensive coverage. This study exploited crowdsourced Waze pothole and weather reports for pavement condition evaluation. Two surrogate measures are proposed, namely, the Pothole Report Density (PRD) and the Weather Report Density (WRD). They are compared with the Pavement Quality Index (PQI), which is calculated using laser truck data from the Tennessee Department of Transportation (TDOT). A geographically weighted random forest (GWRF) model was developed to capture the complicated relationships between the proposed measures and PQI. The results show that the PRD is highly correlated with the PQI, and the correlation also varies across the routes. It is also found to be the second most important factor (i.e., followed by pavement age) affecting the PQI values. Although Waze weather reports contribute to PQI values, their impact is significantly smaller compared to that of pothole reports. This paper demonstrates that surrogate pavement condition measures aggregated by crowdsourced data could be integrated into the state decision-making process by establishing nuanced relationships between the surrogated performance measures and the state pavement condition indices. The endeavor of this study also has the potential to enhance the granularity of pavement condition evaluation.

This study investigated the effectiveness of Balanced Scorecard (BSC) on provision of quality services in selected public organizations in Tanzania. The objective was to investigate the effective of balanced Scorecard on quality services in selected public organizations. The study reveals that BSC tool is more effective compared to previously used tools. Also, the employee’s perception on effectiveness of BSC tool on provision of quality services is positive. The findings of ordinal logistic regression analysis show that the effectiveness of BSC tool increases the likelihood of employees to provide quality services. Further, extended regression namely structural equation modelling shows that the relationship between effectiveness of BSC tool and provision of quality services is distorted by high level of autocratic management style while not distorted by rules, policy and regulations. The study is strongly recommending that there is a need for government and private organisations to adopt BSC as an effective tool for provision of quality services; There is a need of introducing transformational and collaborative management styles in order to account for quality of services; Organizations should continuously enforce regulations, rules and policies; The study should be used by decision makers to set standards of introducing viable and vibrant performance management tools which are result oriented and further studies on uncovered areas on BSC to be undertaken in future.
