Abstract: The territorial redevelopment occupies a very important place in the states because it is not unrelated to their level of development. Also, the redevelopment of territories encompasses several areas: economic, environmental, political, social and logistical. On the other hand, the transport policy is at the crossroads of economic, social, technological and environmental issues. It requires a transversal approach to ensure optimal mobility of citizens and goods. Because of the growth of freight traffic, we are interested in the exchange of physical flows in the hinterlands. This exploratory study has a fivefold purpose. First, we propose to mention some works based on the development of models of the decisional process and we show the multidisciplinary of the problem of territory planning. Second, we clarify the difference between the different types of Geographic Information Systems (GIS) data. Then, we propose to give a classification by approach for models of territorial decision support systems. Thus, we propose a model to identify the different relationships between the territory, the actors involved in decision-making and the different decisional constraints by integrating logistical constraints. Finally, we suggest a generic approach for the conception and generation of a hybrid model MCA-GIS adopted by all the actors intervening in the process of territorial decision takings, we suggest conceptual modeling of this system and we develop a prototype of our suggested model called LOGIS. By this study, this model meets this issue.

Abstract: AIS (Automatic Identification System) is a mandatory navigational equipment on board according to SOLAS (Safety of Life at Sea) convention. It is an automatic tracking system that uses VHF (Very High Frequency) transponders on ships and is used by VTS (Vessel Traffic Services) for monitor vessel movements. Existing AIS data has some principle defects due to radio propagation. This paper provides an approach to predict ship behavior with AIS data. In order to solve the problem that traditional ship behavior prediction needs to establish complex ship motion model, a new ship behavior prediction method based on LSTM (Long Short-Term Memory, LSTM) neural network model of machine learning is proposed. LSTM is the optimization model of RNN (Recurrent Neural Networks). Unlike standard feedback neural networks, LSTM has feedback connections. It can not only process single data points, but also entire sequences of data. These prominent features just match the characteristics of AIS data. The LSTM neural network prediction model is established and the shore is used. Based on the real data of AIS (Automatic Identification System) which ships engaged in the waters of South China Sea, the time series of ship behavior characteristics are extracted to train the model and validate the data. The training data is grouped by MMSI (Maritime Mobile Service Identity) and ensure the equal interval requirements of the ship's navigation behavior sequence data. This paper presents 4 figures with the parameter course, speed, position and the loss curve of LSTM training and testing. The results show that the model has a high accuracy and avoids the complicated process of ship motion modeling. The predicted results can improve the supervision of VTS (Vessel Traffic Services) and play a high practical application value in early warning of ship collision, SAR (Search and Rescue) operation and safety-related issues.

Abstract: Overloaded trucks occurrences is largely common in Nigeria where the axle-load control and enforcement is poor. This paper presents the analysis of the weigh-in-motion survey in Lokoja-Abuja road and the extent of overloaded trucks on the section of the way. The GVW violations amongst the different truck types revealed that 20% of the 2-axle trucks are overloaded, about a half of the 3-axle lorries (50%) are also overloaded, the 4-axle, 5-axle and 6-axle vehicles are the main contributors to truck overloading occurrences in Lokoja-Abuja road, Nigeria with 86%, 73% and 94% overloaded respectively. From the relationship between the numbers of axles each truck category (travelling at a certain speed) and the changes in GVW, the correlation coefficient was 0.855 which was significant at 0.01 level, indicating a compelling contribution of the number axle to overloading on the Nigerian road. The analysis showed that the axle load from weigh-in-motion data is hugely greater than ECOWAS standard weight in Lokoja-Abuja road, which may lead to accelerated deterioration, reducing the service life of the pavement structures.

Abstract: Proper land use planning system does not only give aesthetic look to an urban area, it also increases accessibility and enhances effective spatial interactions. Mobility in Oyo State, Nigeria has been affected over the years as a result of lack or inaccurate and inadequate street addressing system. The buildings are corrugated without proper delineation therefore making accessibility and mobility extremely difficult. This paper therefore examined the challenges of mobility as a result of haphazard layout of street systems and analyzed the consequences of inadequate or lack of street addresses in the State. Data were collected from town planning officials across the three senatorial districts and commercial drivers from various districts using random, purposive and incidental sampling techniques. Five Local Government Areas were randomly selected from each senatorial district. Descriptive and inferential statistics were used to analyze collected data. The analysis revealed that, 66.9 percent of the variance on the effect of transport could be predicted from the independents variables (Ignorance of Individual; Disagreement over Land; Financial Constraint; Illegal Street Address; Lack of Government Interest; Inadequate Data and Lack of Adherence to Master Plan). Results also indicated that; poor street address has a quantifiable impact on the transport operations, builders did not follow approved city plan, official did not enforce and often there used to be disagreements over ownership of streets in conurbations. It is therefore important for government to enforce strict measures and compliance to street address to avoid confusion and encourage smooth transportation delivery.
