Metrino short presentation 2014 10-v20 (akl projec t1+2)Ollie-M
Metrino-PRT (formerly MISTER PRT) is a new, innovative public transportation system for cities. Small (car size), fully automatic, driverless vehicles (pods) travel independently suspended under an overhead network of light guide- ways, 5 to 10m above street level.
Meeting Passenger Demand
All rides are on passenger demand. There are no timetables and no pre-defined routes. Pods are usually waiting for passengers at small stops along the network as well as shopping centers, offices, hotels, hospitals, schools, etc.
Pods are only for individual trips. They carry up to five people, usually acquainted, therefore providing absolute personal safety. All pods, stops and the route network are constantly monitored by security cameras.
Since there are more pods than average daily demand for them, passengers rarely have to wait except occasionally during peak periods. Only those pods carrying passengers (and some empty ones being relocated by the computer system) are in motion. If there is low demand, pods are always waiting at the stops.
Rides take place from any stop directly to your selected destination, without a break during the journey. They travel at an average speed of 50 km/h compared to 30 km/h for metro and 10-20 km/h for buses or trams.
Stops are off-line (like petrol stations along motorways). They do not obstruct the flow of traffic on the guideways.
Passengers enjoy a smooth ride in air conditioned comfort with multimedia services and elevated views.
علی الرغم وجود نقاط ضعف و چالشهای اساسی در حوزه حمل و نقل ریلی , به جهت برخورداری از نقاط قوت چشمگیر و فرصتهاي طلائي پيش روي صنعت ريلي در كشور ، در اين مقاله سعي گرديده بطور مختصر فرصتها و چالشهاي پيش رو در صنعت ريلي مورد بررسي قرار گيرد و هر جند موجز عوامل تاثير گذار بر رشد و توسعه صنعت ريلي مورد تحليل واقع شود. رویکرد اصلی در این مقاله چگونگی تدوین نقشه راه به منظور تحقق اهداف و سیاستهای از پیش تنظیم شده در قالب سند چشم انداز حمل و نقل ریلی می باشد. بي شك با نگاهي بلند مدت و ملي به دغدغه هاي صنعت ريلي و توجه جدي به رشد متوازن آن در كشور مي توان فاصله تاريخي كشور در عرصه صنعت ريلي با سایر گزینه ها و همچنین تكنولوژي هاي روز دنيا را كاهش داده و از پتانسيل هاي شگرف اين صنعت در راستاي اهداف چشم انداز 20 ساله استفاده نمود.
Railways are undergoing major industry changes with management and business planning at the forefront that encompasses operational, customer and intermodal competition issues with innovative technologies removing earlier barriers.

CROSS LAYER DESIGN APPROACH FOR EFFICIENT DATA DELIVERY BASED ON IEEE 802.11P...pijans
Intelligent Transportation Systems (ITS) have been one of the promising technology that has a great
interest attention from many researchers over the world. Vehicular Ad-hoc Network (VANET)
communications environment as a part of ITS opens the way for a wide range of applications such as safety
applications, mobility and connectivity for both driver and passengers to exploit the transport systems in a
smoothly, efficiently and safer way. Several challenging tasks facing adopting VANET functionality for ITS
such as modelling of wireless transmission and routing issues. These research issues have become more
critical due to the high mobility of vehicles nodes (transmitters and receivers) and unexpected network
topology due to the high speed of nodes. In fact, modelling radio propagation channel in VANET
environment which considers as one of a stringent communications environment is a challenging task. The
selection of a suitable transmission model plays a key role in the routing decisions for VANET. Different
propagation models allow calculating the Received Signal Strength (RSS) based on key environmental
properties such as the distance between transmitter vehicle and a receiver vehicle, the gain and antenna
height of transmitter and a receiver vehicles. Hence, it is useful to calculate RSS and SNR values for a
specific propagation model and then these values can be used later for routing decision in order to find the
best path with high SNR. This paper evaluates the performance of different transmission models (free-
space, two-ray and log-normal) in terms of Receive Signal Strength (RSS). In addition, the performance of
such wireless transmission models for vehicular communication in terms of PDR, throughput and delay is
evaluated by applying the proposed cross layer routing approach based on IEEE 802.11p. By using
MATLAB, the obtained results confirm the best packet delivery ratio for our proposed approach, where it
indicates poor quality of DSSS PHY with high number vehicles. The minimum delay achieved when traffic
density is decreased
Reducing Packet Transmission Delay in Vehicular Ad Hoc Networks using Edge No...CSCJournals
VANETs (Vehicular Ad hoc Networks) are highly mobile wireless ad hoc networks and will play an important role in public safety communications and commercial applications. Routing of data in VANETs is a challenging task due to rapidly changing topology and high speed mobility of vehicles. Conventional routing protocols in MANETs (Mobile Ad hoc Networks) are unable to fully address the unique characteristics in vehicular networks. In this paper, we propose EBGR (Edge Node Based Greedy Routing), a greedy position based routing approach to forward packets to the node present in the edge of the limited transmission range of source/forwarding node as most suitable next hop, with consideration of nodes moving in the direction of the destination. We propose Revival Mobility model (RMM) to evaluate the performance of our routing technique. This paper presents a detailed description of our approach and simulation results show that end to end delay in packet transmission is minimized considerably compared to current routing protocols of VANET.

Predictive Data Dissemination in VanetDhruvMarothi
The vehicle itself is an information source that produces a large amount of various information including actual vehicle and environment sensors. The implementation of an efficient and scalable model for information dissemination in VANETs possesses major issues. In this dynamic environment, an ever-growing number of context dissemination messages are leveling up the usage of the channel which affects the network performance. This presentation tries to analyze and assess the key ideas of how to overcome the context data dissemination and how to reduce the amounts of transferred and stored data in a vehicular cooperation environment. This is one of the most prominent topics of pervasive computing.
Cooperative systems offer a universal way for roadside equipment to communicate with vehicles. It provides open connectivity, as promoted by the European Commission. And it also allows multiple applications, to run side by side.
