Abstract: Limited capacity of the power system infrastructure has a limiting effect on the quantity of electrical power that can be transmitted thereby resulting in the system been congested which also affects the quality of electrical energy supplied. Congestion is an undesired effect in power system with serious economic, reliability and security effect on power system infrastructure, which are yet to be adequately quantify in term of cost. Congestion occurrence and management on the power system network has been studied extensively, causes of congestion and various management techniques have been proposed which are at great financial consequences. While setting transmission wheeling prices, congestions are not adequately considered, nor are the management methods accurately financially compensated. Some wheeling pricing techniques however recognises the short coming and takes into consideration the financial cost of congestion and it’s management methods when setting their transmission wheeling costs. This paper is a review of wheeling methods that takes into consideration the cost of congestion and the management techniques when setting wheeling prices and makes a recommendation using financial and economic implication of the occurrence of congestion and the management techniques adopted in reducing the impact when setting wheeling prices, in order to encourage investment into the transmissions system infrastructures.

Abstract: This study investigated the impact of side friction factors on the reduction of effective carriageway width in urban road links in Nakuru Town, Kenya. Linear regression models were developed for each road link, revealing a strong positive relationship between the frequency of side friction factors and the average carriageway width reduction (AVWR). The prediction models highlighted the varying influence of specific side friction factors, such as pedestrians, entry and exit maneuvers, parked vehicles, motorbikes, and bicycles, on AVWR across different road segments. The findings emphasize the importance of context-specific analysis and tailored interventions to effectively address traffic congestion in urban areas, as the complex interplay of side friction factors necessitates comprehensive approaches to traffic management. Regression analyses were conducted on data from 11 major arterial roads, considering factors like pedestrian activity, entry/exit maneuvers, parking situations, and presence of motorbikes, bicycles, and tuk-tuks. Results showed significant positive correlations for most links, with pedestrians, entry/exit maneuvers, and parked vehicles consistently contributing to carriageway width reduction. However, the impact of motorbikes and bicycles varied across locations, underlining the need for location-specific strategies. The study also revealed the intricate interplay among side friction factors, necessitating a holistic approach to traffic management. By understanding these relationships, urban planners and traffic managers can develop targeted strategies to mitigate the impact of side friction factors, improve traffic flow, and enhance overall road network efficiency.
