“…Zhan and Noon (1998) compared various shortest-path algorithms using real road network data and concluded that Dijkstra implementations perform the best while computing a one-to-one shortest path or the shortest paths from a source node to a subset of the nodes (one-tosome). Goodrich and Tamassia (2002) also claim that Dijkstra's algorithm provides the best solution in two situations: (i) computing shortest paths and (ii) constructing minimum spanning trees. Dijkstra implementations have the advantage that they can be terminated as soon as the destination node(s) become permanently labeled, which yields significant computation savings if the destination nodes are in relatively close proximity to the source node (which is the case for any urban scenario).…”

Developing countries are majorly resourceconstrained societies which do not have the financial power to invest in meeting all infrastructure needs. Although there are multiple types of emergency response systems (ERS), the most important ones are the basic essentials-fire, medical and police. Along with emergency response planning for man-made emergencies in an urban scenario, there is a gap in the recent literature about integration of basic ERS into a single framework. We propose a novel framework that first evaluates the existing ERS in place and then provides solutions for improvement with the inclusion of additional facilities at optimal locations. Keeping in mind dynamic congestion patterns and land use resource constraints in different areas of the urban space, the proposed facilities are labeled as either permanent or floating. We also propose three different schemes, each with two competing strategies that cater to a specific type of constraint common to developing nations. Through comparison of system performance metrics like first response time, area coverage, and average response time, the ERS pre-and postimplementation of the framework are compared to check for degree of improvement. A case study of the framework is shown using the city of Chandigarh in India as an example. The framework proposed in the paper takes into account the growth and compactness of urban spaces and can be used to continually assess and improve ERS in mixed use urban spaces after fixed periods of time.

“…Table 1 summarizes the barriers considered in this study that formed the basis for the development of the survey questionnaire. We recognized that asset management systems are expected to play an increasingly essential role in developing countries given the estimated population growth and infrastructure needs within these countries (Ofori 1994;Gwilliam 2003;Lizarralde et al 2013). However, we also found that they have rarely been considered in the academic literature (Rasolonjatovo et al 2015), with the notable exception of Pinard (1987) who identified barriers to implementing pavement management systems in developing countries.…”

“…To establish an asset management system, practitioners in both groups emphasized that organizations should determine and evaluate the conditions of their current management systems. Identifying the strengths and weaknesses of the current management system is a critical step to build upon current systems (Dewan 2004;Gwilliam 2003;Lord-Attivor and Jha 2009;Razak 2009). In addition, top management support has an essential role in enhancing the success of the asset management systems' establishment (FHWA 2007;Hawkins and Smadi 2013;Smith 1992).…”

“…Despite the tremendous current and future growth of infrastructure assets in developing countries, many developing country agencies do not yet have a systematic process to manage their assets (Alkilani and Jupp 2012;Gwilliam 2003;Heravi and Hajihosseini 2011;Mushule and Kerali 2001;Pinard 1987;Sohail et al 2002;Wijnia 2009). However, as these countries develop asset management systems, they need to understand the barriers they may face when implementing these systems.…”

Purpose -The increased need for, and maintenance of, infrastructure creates challenges for all agencies that manage infrastructure assets. To assist with these challenges, agencies implement asset management systems. This exploratory research investigated and compared the importance of barriers faced by agencies establishing transportation asset management systems in the US and Libya to contrast a case of a developed and developing country.Design/ methodology/approach -A literature review identified twenty-eight potential barriers for implementing an asset management system. Practitioners who participated in decisionmaking processes in each country were asked to rate the importance of each barrier in an online survey questionnaire. Descriptive statistics, Kendall Concordance W, and Mann-Whitney were used to analyze the collected data.Findings -Through an analysis of 61 completed questionnaires, 14 barriers were identified as important by both the US and Libyan practitioners. Eleven additional barriers, primarily in the areas of political and regulatory barriers, were determined to be important only for Libya. These 11 barriers provide reasonable insights into asset management systems' barriers for developing countries.Practical implications -The barriers identified from this research can assist decision makers to recognize and overcome these barriers when implementing asset management systems, while recognizing the importance of country conditions. Originality/ value -The research identified standard barriers to implementing asset management systems. It also identified barriers that were specific to the country context, such as political and regulatory barriers in Libya. When viewed with the asset management literature, the results show broad applicability of some asset management barriers and the need to contextualize to country context (e.g., developing countries) for other barriers.

A tentative study of urban and suburban fine particles (PM_2.5) collected in Ouagadougou, Burkina Faso

et al. 2009

The aim of the study was to determine the mass, black carbon (BC), and elemental concentrations in fine particles (PM 2.5 ) and their variations at two sites in Ouagadougou, the capital city of Burkina Faso. The weather situation in Ouagadougou during the field campaign was dominated by high pressure with variable cloudiness and no precipitation. Diurnal temperatures varied between 19 and 38 • C and relative humidity between 10 and 60%. Winds in Ouagadougou were generally coming in from the north, showing a diurnal pattern with gusts of up to 6 m/s during daytime, while evenings and nights were calmer with very stable atmospheric conditions. However, during part of this field campaign, a period of nighttime moderately stable atmospheric conditions occurred with increased wind speed and more easterly winds. Cyclones were used for the PM 2.5 particle collection at both sites. The elemental analysis was done using energy dispersive x-ray fluorescence (EDXRF) spectroscopy. Cl, K, Ca, Ti, Mn, Fe, Cu, Zn, Br, Rb, Sr, and Pb were identified and quantified in most of the samples. The particle mass concentration was 27-164 µg/m 3 while BC varied between 1.3 and 8.2 µg/m 3 . No influence of leaded gasoline was found. Soil dust was identified as a major component of the particles, which was confirmed by comparing with the elements in a soil sample. A significant difference in elemental, BC, and mass concentrations was seen between periods with very stable and moderately stable atmospheric conditions.
