ABSTRAK Infrastruktur merupakan suatu pembangunan fasilitas berupa fisik maupun non fisik yang sengaja dibangun untuk menujang kebutuhan masyarakat baik itu secara sosial maupun perekonomian, salah satu bentuk dari infrastruktur adalah pembangunan jalan, di mana jalan itu juga identik dengan kemacetan khususnya pada wilayah kota-kota besar maupun daerah yang memiliki aktivitas penduduk yang cukup padat. Kawasan Tlogosari Semarang merupakan kawasan yang sering terjadi kemacetan, di karenakan para pengguna jalan lebih banyak menggunakan kendaraan pribadi daripada kendaraan umum, sehingga hal tersebut juga bisa memicu kemacetan karena jumlah kendaraann yang padat, ditambah lagi faktor-faktor lain yang menyebabkan kawasan ini sering macet terlebih pada jam berangkat dan pulang kerja.Identifikasi pada penelitian ini menggunakan metode penelitian kualitatif dengan hasil penelitian yang membuktikan terdapat tiga faktor utama kemacetan tersebut yakni karena wilayah Kawasan Tlogosari Semarang merupakan wilayah yang cukup strategis, sebagai salah satu pusat perdagangan dan jasa, serta merupakan kawasan pendidikan.Kata Kunci : Kemacetan, Kawasan, Jalan ABSTRACT Infrastructure is a construction of facilities in the form of physical and non-physical that is intentionally built to support the needs of the community both socially and economically, one form of infrastructure is road construction, where the road is also synonymous with congestion, especially in large cities and regions. which has a fairly dense population activity.The Tlogosari area of Semarang is an area that often gets traffic jams, because road users use private vehicles more than public transportation, so that it can also trigger congestion due to the dense number of vehicles, plus other factors that cause this area to often get jammed especially on the way to and from work.The identification in this study uses qualitative research methods with research results that prove there are three main factors of the congestion, namely because the Tlogosari area of Semarang is a strategic area, as a center of trade and services, and is an educational area.Keyword: Congestion, Area, Road

City growth often time results in advancement and development in transportation which comes with its attendant changes in road infrastructure and transport support services such as road side mechanic workshops, vulcanizers and bus stops. A byproduct of these attendant contiguous activities and processes is the emission and release of trace heavy metals. Trace heavy metals have been identified as major carcinogens. This study aimed at determining the occurrence and concentration of heavy metals in roadside soils in an expanding third world metropolis. To achieve the aim of the research, the total length of the road within the study section was measured. Ten sample locations were indentified at about 2.5km intervals along the road section under review. The heavy metal concentration was determined the using Buck Scientific 210 VGP Atomic Absorption Spectrophotometer. Heavy metals such as Iron (Fe), Copper (Cu), Cadmium (Cd), Lead (Pb) and Mercury (Hg) were determined. The result of the analysis showed that the concentration values ranged from <0.001 to 48.90 µg/mg. The results also revealed that the experimental sample points recorded higher values than the control samples; however, some of the control points had relatively higher concentration values. This observation may have emanated from the low lying trajectory and topography of the surrounding area, which allows run-off from the road side soils to wash off heavy metals and deposit them at these lower lying areas. The sources of these trace heavy metals are attributed to emissions from motor vehicles that ply the road on a day to day basis. Emanating from the findings, this study recommends that improved public transportation and cleaner sources of energy is recommended.

Road security has become with time a topic of concern in our society as per the increasing number of accidents and deaths occurring on the highways. Regulatory experts on road users have constantly been working for ways to solve this problem and thence better the lives of the citizens. This paper is aimed at proposing a mathematical model integrating specific parameters, describing the dynamic lateral behavior of a vehicle’s tire and chassis systems and enabling to state a relationship between road characteristics and vehicle dynamics. To achieve this, we made used of the fundamental theorems of dynamics for the modeling of the vehicle’s suspended and non-suspended masses and load transfers, then we associated this with the Pacejka Tire model to obtain a complete vehicle model. After the particularization of a global model, a simulator was realized named “DYNAUTO SIMULATOR” which iterates the given variables to produce a consistent result. After an experimental research made on the Ndokoti – PK 24 road section we could, thanks to our simulator determine the maximum speed to have at every turn of this road section and also understand the effect of the modification of a vehicle’s center of gravity on its stability. This work will be an important tool which can be recommended to the regulatory board as a major asset in the road construction policy and also in the improvement of road safety measures.

Traffic congestion is a problem that has long occurred in Indonesia, especially in big cities. Traffic congestion that occurs can cause various losses, one of which is time loss because it can only run at a very low speed. Then it will create a waste of energy, because going at low speed will require more fuel. Congestion is also able to increase the saturation of other road users, not only that traffic jams also have a bad impact on nature which causes air pollution. And there are many more impacts of traffic jams that can make traveling very uncomfortable. One of the locations of traffic jams often occurs on roads located around railroad crossings. Therefore, In this study, it is proposed to make a traffic light sensor adjacent to the train track to anticipate long traffic jams based on atmega8 and infrared sensors, with the stages of collecting data, recording transportation activities at the location of the jam, then designing a sensor device. The system built is to read the volume of vehicles on the road and prioritize the road with the highest volume of vehicles to get the green traffic light condition. Based on the results of the manufacture of infrared sensors and atmega8 can be tested to reduce the level of congestion at crossroads adjacent to the railroad.

Road users other than online public transportation must also be given legal protection and together enjoy the convenience of traffic facilities. Drivers are required to concentrate while driving a vehicle. This is regulated in Law Number 22 of 2009 concerning Road Transportation Traffic, Article 106 that everyone driving a motorized vehicle on the road is obliged to drive his vehicle fairly and with full concentration. The observations made were that attaching a communication device to online public transportation proved that the telephone was used while driving a vehicle. Communicating by telephone while driving a vehicle will cause an accident that will harm other road users. This study discusses the regulations for using the telephone while driving against online motorcycle taxis and law enforcement analysis the regulations for using the telephone while driving against online motorcycle taxis in Bandar Lampung. The results showed the telephone regulations while driving to online motorcycle taxis in Bandar Lampung were Permenhub No. 12 of 2019 Article 4, Article 6, Article 17, Article 18, and Article 19. The results of the analysis of law enforcement on the use of telephones while driving in the form of online motorcycle taxis to contact consumers on their way to the location 3 (three) times, namely 32% (thirty-two per cent) and the intensity of online motorcycle taxis to contact consumers more than 3 (three) times, namely 27% (twenty-seven percent). The analysis data has proven that the intensity of contacting passengers is very much done while driving. Online motorcycle taxi drivers do not obey the rules because they communicate more by telephone while driving.

The purpose of this study was to find out what criminal cases were carried out by punk children, then what factors behind them committed the crime, and why they could enter the punk community. Punk kids are always associated with a negative action, look weird, steal, children are slang, immoral, and other negative things. Sometimes punk children choose to live on the road not only a factor in the conditions of economic difficulties, but also because they enjoy environmental conditions on the road, they feel their families do not care, and lack of education. Research methods The research method used in conducting research on the criminal acts of punk children community is to use qualitative research methods with a sociological juridical approach. Qualitative research methods according to Lexy J Moleong are research that intends to understand the phenomenon of what is understood by the subject of research, such as behavior, perceptions, motivations, actions, etc., holistically and in description in the form of words and language in a natural context. Data collection uses quantitative methods. The results of the study concluded that criminal acts or crimes by punk children were carried out due to economic, family, environmental factors, and lack of education.

Safety on the road is an important consideration for every road user. There are various kinds of traffic signs that are can be employed, all of which are intended to discipline road users and improve their safety. However, Indonesian drivers frequently ignore these safety signs. This is particularly significant given the growing volume of vehicles in Indonesia – and as the number of vehicles has increased so has the number of accidents. This study uses quantitative research methods to explore this correlation and consider the consequences. Keywords: Safety Aspects, Accident, Traffic

One of the most important sectors in infrastructure development in Laos is road construction. However, many road construction projects in Laos suffer from extensive delays. This causes damage such as recurring problems in the road construction industry, and has a negative effect on the success of road construction projects in terms of schedule, cost, quality, safety and the amenity of road users. The goal of this study is to determine the main causes of these delays and to offer remedies. To identify the causes of delays, a questionnaire is designed by modifying one used to measure causes of delays in road construction projects in the West Bank in Palestine and in consultation with engineering experts with more than 10 years of experience in Laos road construction projects. A total of 53 causes of delay are identified as important in Laos. Questionnaire respondents included 35 contractors, 31 owners and 24 consultants in total. The survey results indicate that the five top factors causing road construction delays are: Contractor cash flow; Delayed payment by owner; Difficulties in financing project by contractor; Financial issues related to owner; and Insufficient equipment and vehicles for the work.

This research was conducted to determine the efforts made by the Yogyakarta city government to realize a good mobility system to overcome the congestion that occurs, one of which is at the Janti intersection, Yogyakarta. In its implementation as a breakdown of congestion, it is necessary to know the extent to which the effectiveness and impact arising from the construction of the Janti fly over. This research is a type of descriptive qualitative research that presents factual and systematic data. Data collection is done by observation and literature review in order to dig up information and process and draw conclusions as a qualitative research method. The urgency of the embodiment of smart cities in other cities in Indonesia is the imbalance of population growth with the development of industrialization. Technology-based smart mobility systems are designed to regulate the movement of public transportation and traffic management in a city. The application of information technology aims to have a smooth and convenient impact on traffic. The results of this study explain that the Janti fly over is the primary arterial road that connects the three Janti intersections. This development has an effect on traffic circulation, which is reducing the level of vehicle density and congestion. Not only the positive impact but the negative impact is also felt by residents who live around the fly over, especially since since 2017 the road closure has been put under the Janti fly over.The results of this study can certainly be an evaluation material for the government in reviewing the application of policies that have been made. Given the social and economic impacts that occur due to the construction and closure of the road under the Janti fly over.Penelitian ini dilakukan untuk mengetahui upaya yang dilakukan oleh pemerintah Kota Yogyakarta untuk mewujudkan system mobilitas yang baik guna mengatasi kemacetan yang terjadi salah satunya di persimpangan Janti, Yogyakarta. Dalam implementasinya sebagai pengurai kemacetan, perlu diketahui sejauh mana efektivitas dan dampak yang ditimbulkan dari pembangunan fly over Janti. Penelitian ini merupakan jenis penelitian deskriptif kualitatif yang menyajikan data factual dan sistematis. Pengumpulan data dilakukan dengan observasi dan tinjauan literature guna menggali informasi dan mengolah lalu menarik kesimpulan sebagaimana metode penelitian kualitatif dilakukan. Urgensi perwujudan kota cerdas di kota-kota lainnya di Indonesia adalah tidak seimbangnya pertumbuhan konsentrasi penduduk dengan perkembangan industrialisasi. System smart mobility yang berbasis teknologi  dirancang untuk mengatur pergerakan transportasi public dan traffic management suatu kota. Penerapan teknologi informasi ini bertujuan untuk memberikan dampak kelancaran dan kenyamanan dalam berlalu lintas. Hasil penelitian ini menjelaskan bahwa fly over Janti merupakan jalan arteri primer yang menjadi penghubung simpang tiga Janti. Pembangunan ini berpengaruh pada sirkulasi lalu lintas yaitu pengurangan tingkat kepadatan kendaraan dan kemacetan. Tak hanya dampak positif namun dampak negative juga dirasakan warga yang bermukim di sekitar fly over terlebih setelah sejak tahun 2017 mulai diberlakukan penutupan jalan di bawah fly over Janti. Hasil dari penelitian ini tentunya bisa menjadi bahan evaluasi bagi pemerintah dalam mengkaji penerapan kebijakan yang telah dibuat. Mengingat dampak sosial dan ekonomi yang terjadi akibat adanya pembangunan dan penutupan jalan di bawah fly over Janti tersebut.

Road markings play an important role in road safety because they provide significant information to drivers about the road. For that reason, they must be replaced when they are not correctly perceived by road users. To analyse which are the main factors that affect road marking perception over time, a test section was designed in a two-lane rural highway, running actual traffic over 18 different types of markings fabricated with different combinations of drop-on materials. Chromatic coordinates, luminance and retroreflectivity of each sample were measured during 18 months in order to study their evolution over time. The results obtained show different behaviours depending on the aggregates and application method used. An increment of the durability has been observed with the use of different layers and mixtures of glass microbeads with different sizes.
