... According to traffic analysts, 30 percent of drivers in big cities' urban areas are searching for a parking spot, and they spend an average of 7.8 minutes to find one. This searching process increases traffic while also wastes time, fuel costs, and CO2 emissions (Niculescu et al. 2016). Moreover, a similar pattern of results was obtained by Hamza, et al. (2019) that 66 percent of the public in peak hours of holidays and weekends spend an average of 10 minutes to find a parking lot which ...
Growing population and rapid urbanization brought challenges like traffic congestion,
environmental impacts, energy consumption, and road accidents to cities across the globe.
Istanbul is among the top five congested cities in the world where its residence spends almost
200 hours every year in traffic congestion, to cope with these challenges, cities must take
undertake a shift to become smarter and improve their transportation systems. Therefore,
this study seeks to explore and analyze smart transportation development in the smart city
context with a particular view on Istanbul city to fill this shortage.
This study which is a three step systematic literature review consisting of bibliometric

Traffic condition in Jakarta has reached critical level without the support of adequate public transportation. Jakarta MRT is another transportation mode proposed for the solution. However, this system will not respond to the issue without integration with existing transportation modes i.e., Bus-Trans-Jakarta and LRT. This paper discusses the geotechnical and traffic engineering aspects of the design and construction of Jakarta MRT. In geotechnical perspectives, the fact that soil conditions in Jakarta are soft, so construction requires careful design and method to reduce disturbance to existing traffic conditions. Diaphragm wall used with top-down construction has been proved as the best solution and the use of TBM is required. In traffic engineering perspectives, all existing transportation modes are considered in the determination of MRT station locations as well as the challenge of substructures construction in the soft soil area. Considering public safety during construction, it has been designed with combined elevated railways at the south corridor and subway in the northern corridor. This study concluded that the selection of the station locations considering integrated all public transportation modes is a must and the construction method for subsurface structures should be selected carefully to reduce traffic disturbance in Jakarta and to keep public safety.

Prayer is the second pillar of Islam and it is emphasized after the two sentences of syahadat. It has been said that it’s as perfect and as good as worship. Prayer is one of the obligations for Muslims and must be done both for Mukimin and Musafir. The virtue of prayer in the mosque is the same as the value of 20 degrees of reward compared to prayer elsewhere. With the traffic jam phenomenon that is increasing due to heavy traffic. For someone who is traveling home in the afternoon before maghrib, some people are always confused to do Maghrib prayer because of the lack of information about the nearest mosque. The problem can be solved by finding the shortest path is a problem to find the minimum route from the starting point to the destination point with the shortest route. This research was made to design an application that provides direction to the nearest mosque in the area of Larangan, Tangerang city. In the making of this system to find the shortest path can be solved using the haversine formula and using the java programming language, where java is used to build applications while the database used is the MySQL database and the use of Google Maps API in determining the route.

Recent development on visual sensor networks (VSN) have shown the emergence of VSN as an important class of sensor-based distributed intelligent systems, with unique performance, complexity, and quality of service challenges. Furthermore, the popularity of VSN had attracted researchers and industries from many applications. Basically, VSN consists of a large number of low-power camera nodes, visual sensor networks support a great number of novel vision-based applications. The information provided by the camera nodes from a monitored site were collected data and processed in distributed and collaboratively. The use of multiple cameras in the network provides different views of the scene which enhances the reliability of the captured events. However, the cameras combined with the network's resource produce large amount of image data which require more energy consumption. Many research experts are working and publishing research papers on energy minimization in visual sensor network. However, there are no special attentions given by researchers on multi-layer cooperation routing in visual sensor network (VSN) particularly on the deficiency of forward-thinking innovation. This research proposed a new method that put forward the step and use (CO-VSN) multi-layer routing arrangement in visual sensor network. The performance of the proposed method is then compared with RASE protocol in different parameters and the result shows some meditation change in the stability of the network, increase the network life, reduce packet loss and energy drainage reduce in the VSNs. Even though, the RASE scheme used channel condition for movement of data and yet the proposed CO-VSN used cooperation and demonstrated better results.

This paper demonstrates state of the arts stochastic risk analyzes in assisting decision-making processes in achieving the project objectives in terms of the estimating project costs under uncertainty. The objectives of this study were to; (i) analyze the feasibility of the Trans Sumatra toll road projects section of Medan-Binjai (25.46 km), Indonesia, and (ii) identify and quantify the toll road risk and uncertainty variables influencing the economic feasibility of the project using stochastic approach. This study identified that the risk variables in this study may include; Indonesia Certificate Bank (SBI), inflation, volume of traffic (vehicles), operation and maintenance (O&M) costs, construction costs, land accusation costs, Jakarta Inter-Bank Offer Rate (JIBOR), and design (EED/FED). The initial results of this study (Scenario 1), using concession period of a-35 years with an implementation of the initial tariff of class I vehicles (Rp. 750 / km) showed that the project was considered not financially feasible as 90% probability of the projected net present value (NPV) was negative at the range of Rp. -1.06 trillion to Rp. 2.57 trillion. The project would be financially feasibility after conducting mitigation processes for those the identified risks, such as; providing the government supports (GSs) as much as 40% of the total construction costs as well as land acquisition costs (Scenario 3). This scenario has resulted that there was 90% probability of the projected NPV would be positive at the range of Rp. 0.54 million to 1.894 million. The implementation of the stochastic risk analysis may assist the project managers comprehensively in developing decision-making processes in financing the toll road project.
... Thus, risk mitigation procedure may reduce the toll project risks in a systematic procedure. Furthermore, the positive impacts in the implementation of this toll road complete with adequate traffic signs, road markings, safety devices, smart devices (for example Smart Payment Systems) may also reduce traffic congestion, air pollution, and traffic accidents [33], [34], [35]. Hence, by the implementation a systematic risk management procedure and the improvement of road infrastructure and facilities, hence these efforts ultimately may save many life as well as public money [36], [37]. ...
Constructing a toll road project required relatively high capital outlays and involving complicated activities. The typical of the project is classified as sensitive to risks and uncertainties. Proper risk management during construction lifecycle period may yield substantial certainties in reducing risk costs. The risk costs were calculated using stochastic analyses. The results showed that there were 7 main activities which were considered as the riskiest ones, and in need to manage such as; construction of concrete structures, road pavement, ground works, interest during construction (IDC), escalation costs, base and sub-base course aggregate, and land acquisition activities. This study identified that before conducting risk mitigation, there was 90% probability of the project costs would be at the range of IDR 23.06 Trillion to IDR 23.96 Trillion. After implementing risk mitigation, there was 90% probability the project cost would decrease at the range of IDR 21.53 Trillion to IDR 22.42 Trillion. Risk Management may reduce project risk costs systematically.
Exploring the performance evaluation index system of one-stop smart city app is helpful to promote the design, improvement and development of one-stop city app under the digital society. It is also beneficial for exploring new ways of city operation and building a new model of city governance. Based on the theoretical lens of the improved D&M model, this study proposed an evaluation system with 7 primary indicators which consist of function, design, information quality, service quality, system quality, privacy specification and city influence and 32 secondary indicators by means of literature analysis and expert interviews. It then adopts experts survey and ANP algorithm to determine the indicator weights. From the comparative analysis, it is found that functional indicators and service quality are key to the performance evaluation of one-stop smart city app, and countermeasures and suggestions for improving such app are proposed in terms of core competencies, operation promotion and privacy norms.
At certain times the number of passengers is very difficult to predict. There was a time when the number of passengers occurred a very significant surge. However, there are times when the number of passengers is drastically reduced. This is caused by many factors including time including the holiday season, holidays, and so on. As for other factors such as natural disasters, endemic diseases, and others. The number of passengers must be proportional to the number of vehicles that have been prepared. The company must consider the condition of the vehicle and also the physical condition of the driver. The aim of this study is to conduct passenger forecasting on a coming day. The methodology used is Fuzzy Time Series. The result of the experiment shows that this model has the accuracy of the difference between predictions with real data using PE which is equal to 34.6%.
Managing traffic in a large city has become a topic of great interest in both politics and science. The costs of poor traffic management have been quantified as losses equal to millions of dollars, not counting the unquantifiable value of the time that a person loses in traffic jams. Intelligent transport systems (ITS) offer a set of innovative solutions specific to the management of different modes of transport. This article focuses on the development of an ITS for the city of Quito that allows smart decision-making to direct heavy haul transporters that want to enter the city via one of its main access routes. Technologies such as Sensor Web Enablement (SWE), in association with the Message Queuing Telemetry Transport (MQTT) communication protocol, facilitate the development of a vehicular management platform/system capable of sending notifications in real-time and issuing instructions to drivers regarding traffic delays along routes, average speeds, etc. The system supports a network of heterogeneous sensors accessible through the web. It can integrate any device that uses HTTP protocol. Time interval and location range testing have been undertaken to refine the accuracy of the system and make it adaptable to any geographic situation. The system allows communicate with the server through MQTT or through web services, using technologies such as: MongoDB and GeoJSON. One of the most relevant results is that the degree of accuracy of the system is within appropriate ranges when compared to commercial applications such as Google Maps and Waze.
