ZIMSEC O Level Geography Notes: Transport:Modern Developments in Transport: Road transport
- With technology advancement, increase in human population and growth in national, regional and international trade, there has been tremendous improvements in all modes of transport for good and people.
- The main aims of these improvements are to increase speed, efficiency, safety and comfort.
- These developments differ between developed and developing countries.
- In developed countries, large 6 to 8 lane highways are being constructed to link major urban settlements for example the London to Merseyside motorway, with very elaborate interchange to other towns built along the way.
- Road surfaces are smoothed, with traffic signals working efficiently and road signs placed at convenient points.
- Modern buses with air-conditioning, music and videos transport people daily.
- Each route has well-schedule timetable and number of buses allocated to it.
- Where buses are not enough then taxis can help passenger movement.
- For private cars, more luxurious saloon vehicles with power steering and locking devices have been produced by assembly lines to provide comfort and safety to drivers.
- Tyres being manufactured can withstand great speeds and pressure changes without bursting.
- In urban areas, special parking lots have been established for the urban commuter, complete with security for the cars.
- On heavy vehicles, containerization is the main development which has taken place.
- A container is a large steel box which is lockable.
- Goods are placed inside these boxes which are then locked and loaded onto heavy vehicles.
- The supplier locks and retains one key while the buyer has the other key to unlock the container when it arrives.
- The driver simply transports, without even knowing the contents inside.
- Containerization has the advantage that goods are safe from both thieves and weather elements.
- Handling is easy and fast as the containers are loaded and unloaded mechanically using cranes.
- Damage is kept at a minimum and the container can be used for storage at depots.
- In developing countries, development of roads has meant building more roads and re-surfacing them.
- Older roads are widened and road signs and traffic signals are installed.
- More modern buses such as the Yutong are replacing the older versions such as the AVM.
- Commuter omnibuses are widely in use to transport passengers.
- Police highway patrols in speedy cars, monitor speeds and roadblocks account for unroad- worthy vehicles.
- All this is done for the safety and comfort of the travelling public.
- Bus terminals have shelters to protect travelers against weather elements.
- Battery operated vehicles such as those from Tesla
- Hybrid vehicles that save fuel
- Driver-less vehicles also known as self-driving cars that can drive themselves using Artificial Intelligence
- The use of phone Apps to hail, order and pay taxis for example Uber and Lyft
