This document provides information about various modes of public transportation in London, including buses, the Underground metro system, rail networks, ferries, motorcycles, pedicabs, and trams. It notes that London has an extensive bus network and Underground trains run frequently. Oyster cards can be used on both systems. Transport for London operates the Underground and Docklands Light Railway. Ferries serve as water buses and motorcycles can be hired individually or in groups. Pedicabs, usually tricycles, are available for hire with passenger seating beside the driver. London once had an extensive tram system that has since been replaced with a new modern tram network.

The role of GIS in managing London’s Road Space
London is changing. The population is set to grow to 10 million by 2031 and the economy is recovering. London’s road space is central to enabling this growth. Alan will share with us how the team at TfL are implementing an enterprise-wide GIS as the foundation to support the planning and operational challenges associated with the variety and extent of construction and changes to the road space over the next 20 years. Alan’s challenge is how he can enable the transformation of London’s road space, whilst not impeding the movement of people and goods around the city so that London continues to be a great place to live, work, do business in.
London underground presentation for Digital Railways competition eventKTN
Presentation by London Underground at Transport KTN's information and consortia-building day in Coventry on 25th March 2013 for £5million Digital Railways r&d competition
How the London UNDERGROUND shaped LondonJIM MUKERJEE
The "London Underground" is celebrating its 150th anniversary in 2013. This presentation describes the initial trials and tribulations, dogged tenacity, and miraculous triumphs that transformed transportation, and people's lives, in Victorian London. Even today, the "UNDERGROUND" roundel logo, the "Tube Map", and imaginative posters, are instantly recognized worldwide as iconic symbols of one of the greatest cities of the world, steeped in history, culture, and commerce!
The London Underground, also known as the Tube, is the oldest underground railway system in the world. It has over 270 stations and 11 lines spanning more than 400 km. While the first underground train opened in 1863, much of the network was constructed over 100 years ago and requires extensive maintenance. Technological challenges included building tunnels near historical structures without damage and addressing water issues near the river Thames. The Underground also played an important role as a bomb shelter during World War II and its iconic map design helped popularize the system.
London has an extensive public transport system administered by Transport for London (TfL). This includes the London Underground metro system, opened in 1863 with 270 stations and 11 lines; Tramlink, the city's tram network; over 6,800 bus routes serving 6 million passengers daily; various water transport services on the River Thames and canals; major airports including Heathrow and Gatwick; black cabs; and the Barclays Cycle Hire bike sharing scheme.

The document discusses the event driven real time disruption (RTD) system used on the Victoria Line in London. It describes the challenges of providing timely customer information given the line's high speeds and extensive interchange connections. The system allows control centre operators to select predefined disruption events which then generate associated messages. These messages are transmitted to stations and trains to be dynamically prioritized and displayed based on location. The system provides customers with trusted, journey-specific disruption information to help them make informed travel decisions.
2016 D-STOP Symposium ("Smart Cities") session by CTR's Stephen Boyles. Get symposium details: http://ctr.utexas.edu/research/d-stop/education/annual-symposium/
The document discusses the air interface in GSM systems. It describes:
1) GSM uses TDMA to allow multiple users to share the same radio frequency by dividing each carrier into 8 time slots, with each user assigned a time slot.
2) The TDMA frame structure consists of 8 time slots of 0.577ms each, with a total frame duration of 4.615ms. Guard periods are used between time slots.
3) There are different types of logical channels including traffic channels, control channels, and broadcast channels that carry user data, signaling information, and system parameters respectively.
This document provides a tutorial on quartz crystal resonators and oscillators used for frequency control and timing applications. It covers common applications that require precise frequency control such as communications, navigation, digital signal processing, and military systems. It also discusses oscillator specifications and how improvements in oscillator technology can enable capabilities like improved jamming resistance and spectrum utilization.
The document discusses modulation techniques. Modulation involves imposing information onto a carrier signal by varying its amplitude, frequency, or phase. Specifically, it describes amplitude modulation where the amplitude of the carrier wave is varied proportionally to the amplitude of the message signal. It provides the mathematical representations of the carrier and message signals and how they are multiplied to generate the modulated signal. It also discusses uses of amplitude modulation in applications like air band radio.
WaterSpy is a system that uses wireless devices to monitor water usage and detect leaks. It collects hourly water meter readings and sends the data to an online database through concentrator devices. The online interface called Nemo allows users to view water usage statistics and set alarms. The system helps utilities and customers improve water efficiency and identify issues. It can also be expanded to monitor other resources using additional sensor modules.

ATM is a connection-oriented multi-service network architecture that can carry voice, data and video simultaneously over the same network. It uses fixed-length cells consisting of a 5-byte header and 48-byte payload. Virtual connections called virtual channel connections (VCC) and virtual path connections (VPC) establish logical connections between end users for transmitting data through the network. ATM provides quality of service guarantees and efficient traffic management through these virtual connections and different service categories like constant bit rate, variable bit rate, available bit rate and unspecified bit rate.
