Opis:
Roads and parking areas represent a place of conflict between freight vehicles and other urban activities, especially on mixed residential and commercial streets. This conflict results in traffic congestion, illegal parking, pollution and road safety problems. The challenge is to allocate public space between the right operating activities, parking activities, public transport and so on. To address that, urban logistics delivery bays, also known as loading/unloading (L/U) zones, have become a real solution to facilitate the delivery and pick-up operations of urban freight vehicles, ensure accessibility for delivery drivers, reduce congestion and improve road safety. Therefore, this paper reports on planning and enforcement of urban delivery bays needs. It is part of the urban freight transport (UFT) surveys. This involves consolidating with new contribution the development, implementation and statistical analysis of a survey in order to quantify the need of delivery areas. Compared to the existing literature, this paper presents a mixed applied methodology which is divided into two parts : “Exploratory survey” and “Establishment vehicle observation” survey. These two surveys techniques were conducted to offer an overview of the freight vehicle delivery and pick-up frequency according to the daytime and weekdays and the operations related to the loading/unloading activities. This makes it possible to estimate the delivery bays requirement in the study area. The findings from a methodological and practical angle are illustrated through a real case study in a commercial street in Morocco. The findings suggest that 60% of deliveries are made between 8:00 A.M and 12 A.M, and the movements generated by each establishment are 257 movements. For this, the study zone requires the development of three loading/unloading (L/U) bays. The main contribution is to propose an approach that urban authorities can use to estimate urban delivery areas efficiently and thus allow simple replication of the proposed framework in other cities.

Opis:
The pre-hospital transport of victims of road accidents in Morocco by basic ambulances concerns the majority of the population of victims requiring urgent care. It also constitutes the common service that benefits the entire population of victims, in terms of pre-hospital care. The objective of this contribution is to develop a model for calculating the costs of pre-hospital transport of road accident victims using Time-Driven Activity-Based Costing (TDABC). This model could be effective in better understanding how consumption occurs and how resources are administered and distributed within the pre-hospital care service portfolio. The qualitative research approach that we have adopted in the context of this study has enabled us to map and identify all the activities and tasks carried out in the process of pre-hospital transport of road accident victims. The model obtained is flexible enough to adapt to the various situations of pre-hospital transport of road accident victims by basic ambulances. The application of this model in the Moroccan context, delimited in a well-defined round trip (civil protection - accident site - hospital - civil protection) demonstrates that the said model is valid for cost calculation. The calculations made (217.47 MAD, 224.31 MAD, 225.45 MAD and 226.59 MAD) allow us to identify the possible cases of victims transported by basic ambulance. However, the TDABC, applied to the pre-hospital transport of road accident victims, has some limitations, in particular the estimation of time which is the main key to the allocation of the consumed resources. The results show that the TDABC promotes a better knowledge of all the processes related to the pre-hospital transport service. It allows making visible the value of the costs of the victims of road accidents in the selected patient population. Indeed, when the model is used in the set of routes (black points), decision makers are able to see, on the one hand, the variation of costs between similar pre-hospital transport services and different routes for the same transport services and, on the other hand, the value of the costs of each category of road accident victims' population.

Opis:
The Moroccan government has recently promoted sustainable public transport projects such as tramway services namely in the two largest cities of country, Casablanca and Rabat-Salé. Since its launch, the tramway service is increasingly present in citizens' daily lives in both cities. To maintain its attractiveness, operators and transport authorities should examine the performance of tramway service from user’s point of view. That is, an in-depth understanding of how passengers perceive service quality and what make them satisfied. The purpose of this study is to compare the performance of tramway service in the two cities based on the opinions of a sample size of 613 and 435 individuals in each city. The outcome of this peer comparison allows to determine the strengths and weaknesses of provided service and identify priorities for improvement in each city. Regarding the methodology, we adopted a two-step approach to achieve our research purpose. The first stage intends to compare users' perceptions regarding Service Quality Attributes (SQAs) and overall satisfaction and to identify any significant differences between the two cities. To this end, we applied, in the first stage, a student t-test of two independent samples. The second stage employs an ordered probit regression model to identify the most important SQA; i.e., which most influence the overall satisfaction, and improvements priorities for the current service tramway. The results showed that, in average, passengers found service quality as good and are satisfied with tramway service in both cities. Tram vehicles’ is the best appreciated service attribute in both cities while Comfort in Rabat-Salé and Lines’ connectivity in Casablanca are the least appreciated. Moreover, the service performance of Rabat-Salé tramway exceeds that of Casablanca tramway in terms of service Availability, service Reliability, Fares level, Tram vehicle, Drivers’ competence, Lines’ connectivity, and overall satisfaction. On the other hand, we found that among top six important attributes, Reliability and Administrators should be prioritized for improvement in Casablanca; and staff, Lines, Comfort, and Administrators in Rabat-Salé. Results showed that improvements in all these service aspects would increase significantly overall user’s satisfaction.

Opis:
The urban freight transport (UFT) is an important component of the urban logistics. It represents a driving force for the economic dynamics and attractiveness of a city. It can be treated as all movements of goods necessary for the economic activities, the institutions and the residents of urban life. Through, it faces with problems relating to the congestion, unsafety, atmospheric and noise pollution that constrain its performance and hinder its development. This performance is a complex subject on which a great deal of research has emerged in the last decade. Accordingly, this paper aims to develop a model for assessing the performance of the UFT. The objective is to identify the determinants of the performance of the urban freight transport and measure the impact of each factor. Therefore the first part of this article concerns the elaboration of the model and the formulation of the hypotheses. First, an overview of the factors that could influence the performance of the UFT was identified based on a literature review. The result of this step allowed to model, by mobilizing the GRAI grid (Graph of results and interrelated activities), the UFT system in order to release the decisional links between these factors. Then, the grid will be decomposed into hypotheses explaining the relations between the factors and the performance of the UFT. The formulation of each hypothesis will be based on all the theoretical works that have treated it. The second part includes the empirical study to test the model using the partial least squares (PLS) analysis. Therefore, we conducted a survey among managers and users of the UFT in the city of Fez. A hypothetico-deductive approach has been used with a sequential methodological complementarity between qualitative analysis for exploratory purposes and the support of quantitative analysis for confirmation. The results of the test, confirm a significant influence of the identified factors on the UFT performance. The practical scope of this paper is to provide a decision-making framework for urban management department explaining the impact of these factors on the UFT performance.
