Abstract
Theoretically there is a fundamental relationship between the number of accidents, speed and volume. Mathematical and graphic relationships can be used to understand those traffic behaviour. This model is expected to provide estimates or predictions of traffic accident figures as a basis to improve traffic safety on Surabaya-Gempol toll road. Data processing is performed using the non-linear Poisson regression method because accident rates are discrete and cannot be negative. From the results it is known that in Waru-Sidoarjo segment, the lower the speed, the denser the traffic volume and accidents will remain constant. In the Sidoarjo-Porong section, the denser the traffic volume, the speed will decrease and the accident rate will increase. In Kejapanan-Gempol section, the denser the traffic volume, the less accidents will occur.

Abstract
The analysis of channel measurement based ray-tracing (RT) simulation nowadays is considered as one of the most effective in solving traffic railway communication. In order to handle the increasing capacity demand for higher transmission capabilities, the railway communication system should be support by high data rate connectivity and feasible in many areas included urban area. The channel characteristic for railway scenario are explored by RT analysis method in the simulation at 800 MHz with 20 MHz bandwidth. Also most straightforward way to increase capacity is to add more bandwidth. The scenario for high speed railway (HSR) are modeling in urban area. However due to channel information parameters are extracted and incorporated into a 3GPP-like random channel generator. Well to analysis the channel measurement depend on ray-tracing for HSR can be adjusted with the channel information on the area.

Abstract
Ballastless track is designed for long time period of service up to 60 years or even more. It has main goal to achieve a high performance and less significant maintenance during the service. One development of the standard design, which can be introduced to improve a conventional in-situ casted railway slab track, e.g. continuously reinforced concrete pavement (CRCP), is by implementing active crack control construction type. In this system, a CRCP slab is cut in a spacing interval immediately after it reaches a certain level of sufficient hardening state. This study is conducted to discuss the standard design procedures and the performance of slab track using CRCP as rail supporting structure (e.g. Rheda 2000) based on the long year experience of its implementation in Germany and to study parameters of cut spacing and subgrade bearing capacity of the Rheda-2000 designed with active crack control system. A static Finite Element Analysis (FEA) has been carried out using 3D model in ANSYS to assess the performance of the standard Rheda-2000 designed with active crack control system based on ultimate limit state design criteria. The substructure support is also ranged to investigate the limit performance of the system and to represent different levels of subgrade bearing capacity. The assessment is mainly based on the safety factor and comprises a combination of theoretical, analytical, empirical and FEA methods of ballastless track design procedures. The results demonstrate that there is a critical length of cut spacing of the slab and certain required bearing capacity limit of the substructure to achieve an equilibrium and optimal slab track designed with active crack control system.

Abstract
In improving the traffic management system in accordance with Law No. 22/2009, efficient and effective road infrastructure is needed which includes several aspects including safe, secure, fast and convenient. One such road infrastructure is road markings which have an important role in traffic especially the influence of the level of visibility generated by the road markings. This can affect the traffic especially at night where the level of visibilty produced by the markers is very influential on motorists. One of the factors that influence the lack of visibility level of the markers is the use of glassbead in the painting process. Therefore, it is necessary to study related to the use of glassbead levels on road markings, especially on thermoplastic markers where thermoplastic markers are widely used in several roads and conduct studies related to whether the visibility standards produced by these markers in the form of mark reflectivity levels are in accordance with field implementation.

Abstract
Commercial freight vehicle is essential for daily goods distribution from one place to another. It is quite common that freight operators load their trucks beyond the allowable weight limit to maximize profit. This behavior leads to deterioration of road surface in Indonesia, which significantly increases road maintenance cost. To remedy the situation, anterior strategy would be to provide overload prevention device, while posterior strategy should measure vehicle weight while it is moving and detect the overloaded vehicle. This paper deals with the first strategy, in which a bluetooth-based wireless strain measuring system is developed. The main subsystem which consisted of strain gage, Wheatstone bridge, Arduino Nano plus strain amplifier and Bluetooth modules, is placed on the load picking component of the vehicle, while additional subsystem consisted of Arduino Nano plus Bluetooth module and relays, is attached to the ignition wiring. Laboratory experiment showed that the system works and the design achieved the intended purpose, in the sense that it will cut engine power supply and trigger the alarm when the vehicle is overloaded. As a future work, we will install the system in a real vehicle to observe the performance of the system in an actual situation.

Abstract
Cracks are one type of pavement surface damages, whose assessment is very important for developing road network maintenance strategies, which aims to ensure the functioning of the road and driving safety. Existing methods for automatic crack detection depend mostly on expensive equipment and high maintenance and cannot divide the crack segments accurately. This paper discusses an automation method of classification and segmentation of asphalt pavement cracks. The goal of the research is to classify asphalt pavement cracks using the classification method of the Support Vector Machine (SVM) algorithm and segmentation method of the OTSU algorithm. The OTSU algorithm for segmentation has advantages in choosing the optimal threshold that is stable. This algorithm is proven to be more effective and stronger than conventional segmentation algorithms. For detection results, the proposed method achieves overall accuracy.

Abstract
Braking system by using friction is critical in electric vehicles. However, the use of excessive friction will cause a decrease in braking performance. One alternative solution is to use the Eddy current braking system (ECB). ECB is a braking system that utilizes eddy currents generated by induction when the rotor rotates due to the magnetic field produced by the stator. This study discusses the use of ECB for electric motorcycle disk braking systems. This study aims to determine the effect of air gap on braking performance of ECB on an electric motor. The finite element (FEM) method was used in ECB performance modeling. The results showed that the need for a combination of motorcycle disks with disks that match the ECB with maximum torque at 12Nm. It can be concluded that using ECB can effectively increase the braking power by reducing friction on the braking disk. It means the ECB system can extend the life of the braking disc.
