Transport enables trade between people, which is essential for the development of civilizations. Better transport has the potential to improve the lives and livelihoods of billions of people by facilitating access to jobs, markets, and essential services such as healthcare or education. The World Bank provides financial and technical assistance to help countries implement sustainable mobility solutions that create real, lasting development benefits. There are also numerous privately run services that use cars and minibuses of various types throughout Pakistan, providing a reliable and quick means of transport. Recently, the Radio Cab was introduced in Pakistan, which allows riders to call a toll-free number to get in touch with the closest taxi stand.

There are a wide range of other sensors, measuring chemical & physical properties of materials. A few examples include optical sensors for Refractive index measurement, vibrational sensors for fluid viscosity measurement and electro-chemical sensor for monitoring pH of fluids. In contrast to contact sensors, non-contact sensors are devices that do not require a physical touch between the sensor and the object being monitored in order to function. A familiar example of this type of sensor is the motion detector used in security lights.

Far from being restricted to just the home, the Internet of Things can be found in an array of devices, industries and settings. From smart blackboards in school classrooms to medical devices that can detect signs of Parkinson's disease, IoT is rapidly making the world smarter by connecting the physical and the digital. The elastic nature of cloud computing is great for IoT scenarios where data might come in intermittently or asynchronously. And many of the big cloud heavy hitters — including Google, Microsoft, and Amazon — have IoT offerings.

The locomotive can be powered by steam, by diesel, or by electricity supplied by trackside systems. Alternatively, some or all the cars can be powered, known as a multiple unit. Also, a train can be powered by horses, cables, gravity, pneumatics, and gas turbines. Railed vehicles move with much less friction than rubber tires on paved roads, making trains more energy efficient, though not as efficient as ships. Modes of transport include air, land , water, cable, pipeline, and space. The field can be divided into infrastructure, vehicles, and operations.

Highly Accessed Articles

Editors select a small number of articles recently published in the journal that they believe will be particularly interesting to authors, or important in this field. The aim is to provide a snapshot of some of the most exciting work published in the various research areas of the journal. Metal-oxide-semiconductor technology originates from the MOSFET (MOS field-effect transistor, or MOS transistor) invented by Mohamed M. Atalla and Dawon Kahng in 1959, and demonstrated in 1960. MOSFET sensors were later developed, and they have since been widely used to measure physical, chemical, biological and environmental parameters. If the output signal differs from the correct value by a constant, the sensor has an offset error or bias.

Buses are the cheapest mode of transport but are not necessarily flexible, and taxis are very flexible but more expensive. In the middle is demand-responsive transport, offering flexibility whilst remaining affordable. Infrastructure is the fixed installations that allow a vehicle to operate. It consists of a roadway, a terminal, and facilities for parking and maintenance. For rail, pipeline, road, and cable transport, the entire way the vehicle travels must be constructed. Air and watercraft are able to avoid this, since the airway and seaway do not need to be constructed.
