Motorcycles that see: Multifocal stereo vision sensor for advanced safety systems in tilting vehicles

Advanced driver assistance systems, ADAS, have shown the possibility to anticipate crash accidents and effectively assist road users in critical traffic situations. This is not the case for motorcyclists, in fact ADAS for motorcycles are still barely developed. Our aim was to study a camera-based sensor for the application of preventive safety in tilting vehicles. We identified two road conflict situations for which automotive remote sensors installed in a tilting vehicle are likely to fail in the identification of critical obstacles. Accordingly, we set two experiments conducted in real traffic conditions to test our stereo vision sensor. Our promising results support the application of this type of sensors for advanced motorcycle safety applications

Towards sustainable transport: wireless detection of passenger trips on public transport buses

An important problem in creating efficient public transport is obtaining data about the set of trips that passengers make, usually referred to as an Origin/Destination (OD) matrix. Obtaining this data is problematic and expensive in general, especially in the case of buses because on-board ticketing systems do not record where and when passengers get off a bus. In this paper we describe a novel and inexpensive system that uses off-the-shelf Bluetooth hardware to accurately record passenger journeys. Here we show how our system can be used to derive passenger OD matrices, and additionally we show how our data can be used to further improve public transport services.Comment: 13 pages, 4 figures, 1 tabl

Istihsan Concept in Multi Contract Online Transactions of Go-Food Services in The Go-Jek Application

Technological developments are very influential on the lives of the world's people, one of which is used for business purposes or known as Electronic Commerce (E-Commerce). Several E-Commerce facilities such as online transportation, online payments, online shopping, are practical facilities that are in great demand by the public. As an online food delivery service known as Go-Food. Go-Food application transactions or food orders have several contracts (multi-contract). This research is a field research. The data collected is analyzed descriptively qualitatively, that is, describes as clearly as possible the related data, then concluded deductively, that is, draws conclusions from statements that are general to specific. So that understanding the research results can be easily understood and understood. Some of the contracts in Go-Food transactions are as follows: PT. Go-Jek and merchants. PT. Go-Jek with merchants is an ijarah agreement. Transactions between Pt. Go-Jek and Driver, a collaboration between Go-Jek and drivers and known as the cooperation system (Syirkah). Contract between the consumer and the driver, if the consumer makes a payment using his own go-pay system, the transaction that occurs between the two is buying and selling, but if it is in cash, then there is a wakalah contract, here it will also be a qardh contract because the consumer owes it to the driver. Contracts between drivers and merchants, there are buying and selling activities between drivers and merchants, buying and selling represented by the driver to the merchant, representative transactions like this in Islamic law are known as wakalah contracts. With the istihsan method, economic activities that provide convenience and good benefits without harm and injustice to mankind can be answered and proven by the istihsan method, so that sharia economic activities can always exist and can compete with conventional economics

Review of current study methods for VRU safety : Appendix 4 –Systematic literature review: Naturalistic driving studies

With the aim of assessing the extent and nature of naturalistic studies involving vulnerable road users, a systematic literature review was carried out. The purpose of this review was to identify studies based on naturalistic data from VRUs (pedestrians, cyclists, moped riders and motorcyclists) to provide an overview of how data was collected and how data has been used. In the literature review, special attention is given to the use of naturalistic studies as a tool for road safety evaluations to gain knowledge on methodological issues for the design of a naturalistic study involving VRUs within the InDeV project. The review covered the following types of studies: •Studies collecting naturalistic data from vulnerable road users (pedestrians, cyclists, moped riders, motorcyclists). •Studies collecting accidents or safety-critical situations via smartphones from vulnerable road users and motorized vehicles. •Studies collecting falls that have not occurred on roads via smartphones. Four databases were used in the search for publications: ScienceDirect, Transport Research International Documentation (TRID), IEEE Xplore and PubMed. In addition to these four databases, six databases were screened to check if they contained references to publications not already included in the review. These databases were: Web of Science, Scopus, Google Scholar, Springerlink, Taylor & Francis and Engineering Village.The findings revealed that naturalistic studies of vulnerable road users have mainly been carried out by collecting data from cyclists and pedestrians and to a smaller degree of motorcyclists. To collect data, most studies used the built-in sensors of smartphones, although equipped bicycles or motorcycles were used in some studies. Other types of portable equipment was used to a lesser degree, particularly for cycling studies. The naturalistic studies were carried out with various purposes: mode classification, travel surveys, measuring the distance and number of trips travelled and conducting traffic counts. Naturalistic data was also used for assessment of the safety based on accidents, safety-critical events or other safety-related aspect such as speed behaviour, head turning and obstacle detection. Only few studies detect incidents automatically based on indicators collected via special equipment such as accelerometers, gyroscopes, GPS receivers, switches, etc. for assessing the safety by identifying accidents or safety-critical events. Instead, they rely on self-reporting or manual review of video footage. Despite this, the review indicates that there is a large potential of detecting accidents from naturalistic data. A large number of studies focused on the detection of falls among elderly people. Using smartphone sensors, the movements of the participants were monitored continuously. Most studies used acceleration as indicator of falls. In some cases, the acceleration was supplemented by rotation measurements to indicate that a fall had occurred. Most studies of using kinematic triggers for detection of falls, accidents and safety-critical events were primarily used for demonstration of prototypes of detection algorithms. Few studies have been tested on real accidents or falls. Instead, simulated falls were used both in studies of vulnerable road users and for studies of falls among elderly people

Semi Team Driver Dies after Being Ejected from Sleeper Berth

In the fall of 2009, a husband-wife semi driver team traveled south on a four-lane interstate. They were driving a semi-tractor trailer loaded with air freight. It was nighttime; the husband was driving, and the wife was in the sleeper berth. There was an unoccupied car parked on the right shoulder. The husband crossed the fog line on the right, sideswiped the car, traveled through a guardrail, and down an embankment toward a road below the interstate. During the trajectory of the semi-tractor trailer, the unit jackknifed; the trailer detached from the semi then struck the semi, and both the husband and wife were ejected. The husband was found on the embankment, and the wife was found under the contents of the semi. A witness to the crash called emergency services. They arrived and transported the husband to the nearest trauma hospital. The coroner was contacted, and upon his arrival to the scene, declared the wife dead at the scene. To prevent future occurrences of similar incidents, the following recommendations have been made: Recommendation No. 1: Companies should provide new and refresher truck driver safety training for company drivers that includes driver distraction and defensive driving techniques as they pertain to fatigue. Recommendation No. 2: Passengers using the sleeper berth in a moving semi should use the restraint system currently provided by the manufacturer. Recommendation No. 3: Sleeper berth occupant protection systems should be redesigned to provide comfort as well as safety. Recommendation No. 4: Electronic stability systems should be mandatory equipment on all commercial vehicles. Recommendation No. 5: Commercial vehicle carriers should implement and enforce a workplace policy that requires drivers to wear seat belts while operating a commercial vehicle. Recommendation No. 6: A comprehensive motor vehicle safety assessment of Kentucky’s interstate system needs to be performed in the area where the collision took place
