Train induced dynamic response of a pedestrian tunnel under a four-track surface railway for different soil water contents

A reinforced concrete pedestrian tunnel is constructed under a four-track surface railway. Heavy rainfall and soil exposure to drying lead to soil with different water content throughout the year. A railway is an open utility that is subject to rainfall without control on the quantity of the water on it and when there is a tunnel under a railway, the water content of the soil around the tunnel is very influential. This research shows the effects of change of water content in the soil around a pedestrian tunnel under a four-track surface railway. The pedestrian tunnel and the soil block around the tunnel are modeled in 3D by the FEM and are studied under the vibrations induced by the moving trains on the four-track surface railway for different soil water contents and the effects of the soil water content on the dynamic behavior of the tunnel and the surrounding soil are demonstrated.

Evaluation of the Effectiveness of a HAWK Signal on Compliance in Las Vegas Nevada

There is a continuous large number of crashes involving pedestrians in Nevada despite the numerous safety mechanisms currently used at roadway crossings. Hence, additional as well as more effective mechanisms are required to reduce crashes in Las Vegas, in particular, and Nevada in general. A potential mechanism to reduce conflicts between pedestrians and vehicles is a High-intensity Activated crossWalK (HAWK) signal. This study evaluates the effects of such signals at a particular site in Las Vegas. Video data were collected using two cameras, facing the eastbound and westbound traffic. One week of video data before and after the deployment of the signal were collected to capture the behavior of both pedestrians and drivers. T-test analyses of pedestrian waiting time at the curb, curb-to-curb crossing time, total crossing time, jaywalking events, and near-crash events show that the HAWK system provides significant benefits.

Pedestrian lower extremity injury risk in car-pedestrian collisions

Here, the pedestrian lower extremity injury risk was studied using the real world accident data. For this purpose, 354 cases with pedestrian lower extremity injuries selected from the german in-depth accident study(GIDAS) database were used to conduct the one-way variance analysis to determine the effects of impact speed, pedestrian age, height and weight on the pedestrian serious lower extremity injuries risk. Then, the pedestrian serious lower extremity injury risk model was established. The results showed that the impact speed and pedestrian age are significant factors affecting pedestrian lower extremity serious injuries, but the pedestrian weight and height are not; the risk of injury is positively related to impact speed and pedestrian age; the pedestrian serious lower extremity injury risk reaches 50% when the impact speed is 43 km/h.

Investigation on the use of waste tyre crumb rubber in concrete paving blocks

This paper investigates the utilization of waste tyre crumb rubber as the fine aggregate in precast concrete Paving block (PCPB). PCPB\'s are generally preferred for city roads, pedestrian crosswalk, parking lots and bus terminals. The main aim of this paper is to evaluate the mechanical properties of wet cast PCPB containing waste tyre crumb rubber. The mechanical properties were investigated using a density, compressive strength, split tensile strength and flexural strength tests at 7, 28 56 days according to the IS 15688:2006 and EN1338. The wet cast method was followed for producing PCPB samples. The fine aggregate (river sand) was replaced with waste tyre crumb in percentage of 5%, 10%, 15%, 20% and 25% by volume. All the test results were compared with the conventional PCPB (Without rubber). The test results indicate its feasibility for incorporating waste tyre crumb rubber in the production of PCPB by the wet cast method.

Role of ultrasonography in blunt abdominal trauma

Objective The aim of the study was to assess the role of ultrasonography (US) focused assessment with sonography in trauma (FAST) at the time of presentation and ultrasound repeated after 12–24 h in early diagnosis of intra-abdominal injury (IAI) following blunt abdominal trauma (BAT) and for follow-up. Background US was used in patients with IAI. Trauma is the most common cause of mortality. The most common mechanisms resulting in BAT among patients were motor vehicle collisions (73%), motorcycle collisions (7%), auto–pedestrian collisions (6%), and falls (6%). Patients and methods This is a prospective study of 50 patients presented to the Emergency Room of Menoufia University Hospital with BAT who underwent US and FAST examination at the time of presentation and were followed up with US after 12–24 h. Of them, 12 patients were hemodynamically unstable, six patients had severe intra-abdominal hemorrhage and entered the operation theater urgently after FAST examination, and the other six patients entered the ICU for urgent care, FAST findings, and follow-up. US findings were correlated with patients' clinical data. Results US is very useful in the follow-up of patients with minor IAI and it decreases the use of computed tomography. However, ultrasound is operator dependent and could overlook lacerations of solid organs and gastrointestinal injuries. Therefore, contrast-enhanced computed tomography is still considered the gold standard in the evaluation of the exact site and the degree of IAI. Conclusion We concluded that ultrasound is considered the best modality in the initial evaluation of patients with BAT. However, repeated ultrasound in patients of BAT increases the sensitivity of ultrasound for causing intra-abdominal bleeding to 100%.

CHILD AND ADULT CLASSIFICATION USING BIOMETRIC FEATURES BASED ON VIDEO ANALYTICS

As the number of social insecurity in regard to social crimes is on its rise, it requires a CCTV camera a higher accuracy in detecting the objects including pedestrians for efficient work of catching criminals. As the importance of the function of pedestrian detection is socially agreed upon, more studies on image and video based pedestrian detection have been conducted. In terms of that, the goal of this study is classification of pedestrian in two categories as a child and an adult. In this study, Haar cascade classifiers are used. This method first detects a full body and a head. Then, it measures the biometry given the relative proportioning length of a full body and a head. Moving average algorithm is used to obtain threshold ratio. Experimental results show the accuracy 100% for children and 64.5% for adults.

Evaluation the Performance of Al-Horh Signalized Intersection Using ArcGIS (ModelBuilder)

Signalized intersections are key elements in the urban transportation network where carry heavy traffic of motorized and non-motorized vehicles and pedestrians the intersection during peak periods. Intersection congestion is expressed in terms of level of service (LOS) as defined by the Highway Capacity Manual (HCM).Level of service is defined in terms of delay and ranges from LOS A (free-flow conditions) to LOS F (long delays). Delay represents an average stopped delay per vehicle fora 15-minute analysis period.
 The objective of this paper is to evaluate the operational capacity of intersection (AL-Horh) in AL-Kut city.AL-Horh intersection is a ground intersection with four legs. Itrepresent one of the main intersections in Al-kut city for it links the traffic coming from Al- Zafaf Street to Al- Hora and Al- Kafaat Street. The volumes of traffic get congested in the morning and evening at this intersection.To achieve the evolution performance of intersection 700 TVL Samsung video cameras have been used to measure traffic volume in the intersections with 3.6mm lens and total station were used to survey the intersection whereas ArcGIS (ModelBuilder) were used for processing for the purposes traffic analysis process.The operational analysis of the existing conditions of this intersection indicates that the LOS is (F) with an intersection delay value of 175.363sec. /vehicle.
