Data on the daily activity of private cars form the basis of many studies in the field of transportation engineering. In the past, in order to obtain such data, a large number of collection techniques based on travel diaries and driver interviews were used. Telematics applied to vehicles and to a broad range of economic activities has opened up new opportunities for transportation engineers, allowing a significant increase in the volume and detail level of data collected. One of the options for obtaining information on the daily activity of private cars now consists of processing data from automated vehicle monitoring (AVM). Therefore, in this context, and in order to explore the opportunity offered by telematics, this paper presents a methodology for obtaining origin–destination flows through basic info extracted from AVM/floating car data (FCD). Then, the benefits of such a procedure are evaluated through its implementation in a real test case, i.e., the Veneto region in northern Italy where full-day AVM/FCD data were available with about 30,000 vehicles surveyed and more than 388,000 trips identified. Then, the goodness of the proposed methodology for O-D flow estimation is validated through assignment to the road network and comparison with traffic count data. Taking into account aspects of vehicle-sampling observations, this paper also points out issues related to sample representativeness, both in terms of daily activities and spatial coverage. A preliminary descriptive analysis of the O-D flows was carried out, and the analysis of the revealed trip patterns is presented.

Currently, the increase of transport demands along with the limited capacity of the road network have increased traffic congestion in urban and highway scenarios. Technologies such as Cooperative Adaptive Cruise Control (CACC) emerge as efficient solutions. However, a higher level of cooperation among multiple vehicle platoons is needed to improve, effectively, the traffic flow. In this paper, a global solution to merge two platoons is presented. This approach combines: (i) a longitudinal controller based on a feed-back/feed-forward architecture focusing on providing CACC capacities and (ii) hybrid trajectory planning to merge platooning on straight paths. Experiments were performed using Tecnalia’s previous basis. These are the AUDRIC modular architecture for automated driving and the highly reliable simulation environment DYNACAR. A simulation test case was conducted using five vehicles, two of them executing the merging and three opening the gap to the upcoming vehicles. The results showed the good performance of both domains, longitudinal and lateral, merging multiple vehicles while ensuring safety and comfort and without propagating speed changes.

The housing environment that appears in many urban areas today, is available in the form of real estate and in the form of simple housing. The existence of these houses is equipped with supporting infrastructure. One of them is the availability of open space as a public facility, which can be utilized by all residents of housing. If you look at the historical aspects of past traditional settlements, such as the Tanean Lanjang Madura settlement, the Samin Bojonegoro Community Village, the Sumatra Karo Batak Village, and so on, it is found that there is open space as a public space. Where the function and role of open space are used for joint activities, gathering places and socializing, as well as the center of orientation of several groups of houses, so that the location tends to be in the center. The purpose of this study is to see the existence of open space of traditional settlements (past) and present. As well as analyzing the activities carried out by the pas community and its current development. By using the method of field observation (observation) and qualitative descriptive analysis, the results show that the existence of open space in the present, such as in residential or residential groups, still exists. If in the past traditional settlements, the existence of open spaces was used as a means to gather and socialize, then in its current development, open space could be used as a means of playing and exercising for children, recreational activities (gathering on holidays), supported economic activities (traders who sell), as well as a means of worship (Eid al-Fitr / Eid al-Adha). This shows the development and diversity of functions and activities in the open space, so that its utilization can increase economic values, religious values and other social values.

The Impact

The COVID-19 pandemic has changed the world patterns including economic, human needs, and daily activity. Millions of people have been called to stay at home, keep physical distancing, and many economic activities are closed as a precautionary measure. As a result, many people are unable to work and earn money, especially those who receive a daily salary. For a certain group of people such as homeless children, this situation is bad. Without a proper home, lack of basic needs and social services makes them exposed to multiple deprivations. In this regard, in this conceptual chapter, the researcher will report the impact of the COVID-19 pandemic on homeless children in Malaysia. Aside from that, the researcher will also explain the roles of a social services provider to help homeless children meet their needs during the pandemic. This conceptual chapter enables agencies who work with vulnerable children, policymakers, and child social services providers to utilize the input to frame special social care programs for homeless children during the spread of the pandemic.
