Road signs have three basic categories – regulatory, warning, and guide signs — but they can also be sorted by color and shape.
A warning sign is a type of sign which indicates a potential hazard, obstacle or condition requiring special attention. Some are traffic signs that indicate hazards on roads that may not be readily apparent to a driver.
Smart traffic lights or Intelligent traffic lights are a vehicle traffic control system that combines traditional traffic lights with an array of sensors and artificial intelligence to intelligently route vehicle and pedestrian traffic. They can form part of a bigger intelligent transport system.
Traffic lights (or traffic signals) are lights used to control the movement of traffic. They are placed on roads at intersections and crossings. The different colors of lights tell drivers what to do.
These signs are yellow with black lettering or symbols and most are diamond-shaped. These signs warn you to slow down and be prepared to stop if necessary; a special situation or hazard is ahead.
Highway signs serve a number of purposes. One purpose they serve is to alert drivers to the speed limit for a particular roadway. They also help bring attention to detours, construction work, and hazards, such as sharp turns and steep hills.
The Yield sign (RA-2) has a triangular shape reserved for this sign only and consists of a white triangle on a red background. The standard size of a Yield sign is 750 mm x 750 mm x 750 mm and it is the minimum size permitted on the provincial highways.
The safety, as well as the smooth flow of traffic is very important. The major task of the traffic management centres is to process, collect, and forward the necessary information about a certain traffic situation. Furthermore, it also helps in guiding and managing the traffic on various roads.
The one-hit solution
- Widen roads.
- Narrow roads.
- Add bus lanes.
- Remove bus lanes.
- Build tunnels.
- Build a new ring road.
- Build a light rail network.
- Switch off traffic lights.
Traffic signs are utilized as a method of warning and guiding drivers, helping to regulate the flow of traffic among vehicles, pedestrians, motorcycles, bicycles and others who travel the streets, highways and other roadways.

Traffic management. Traffic management is a key branch within logistics. It concerns the planning, control and purchasing of transport services needed to physically move vehicles (for example aircraft, road vehicles, rolling stock and watercraft) and freight.
Traffic Management Systems (TMS) provide permanent control across the network, automatically sets routes for trains and logs train movements as well as detects and solves potential conflicts.
Signs. Traffic signs are divided into three basic categories: regulatory, warning, and guide signs. The shape of a traffic sign communicates important information about the sign's message. In poor visibility conditions, such as heavy fog, you may be able to make out only the shape of a sign.
What is Traffic System. 1. an specific traffic net with its traffic demand and its control policies. Learn more in: Optimization of Traffic Network Design Using Nature-Inspired Algorithm: An Optimization via Simulation Approach.
A traffic manager's main objective is to ensure that all marketing collateral and work from account services flows efficiently to creative and production departments. They are responsible for keeping everyone on task and projects on deadline, handling the logistics and keeping all parties updated on the progress.
The transportation problem is a special type of linear programming problem where the objective is to minimise the cost of distributing a product from a number of sources or origins to a number of destinations.
Transport is important because it enables communication, trade and other forms of exchange between people, that in turn establishes civilizations. Transport plays an important part in economic growth and globalization, but most types cause air pollution and use large amounts of land.
It may be carried out by Trucks, Buses, Tempos, and Taxis etc.
- Objectives of Transport Costing:
- (a) Cost Ascertainment: Finding out the costs of operating the vehicles.
- (b) Price Fixation: ADVERTISEMENTS:
- (c) Quotations:
- (d) Decision Data:
- (e) Control Over Maintenance:
- (f) Operational Efficiency:
- (a) Reliable Prices:
The mission of the U.S. Department of Transportation (DOT) is to ensure our Nation has the safest, most efficient and modern transportation system in the world, which improves the quality of life for all American people and communities, from rural to urban, and increases the productivity and competitiveness of American
What Are the Goals of Logistics?
- Increasing Efficiency.
- Rapid Response.
- Fewer Unexpected Events.
- Minimum Inventory.
- Reduced Transportation and Logistics Cost.
- Quality Improvement.
The goal should be that every product will be delivered to the final destination without any damage or loss of value. An additional transportation goal is the timely delivery of goods. A common goal that transportation companies share is that freight will be delivered on time, every time. .
Transportation planning is the process of defining future policies, goals, investments, and designs to prepare for future needs to move people and goods to destinations.
Public transit provides a basic mobility service to these persons and to all others without access to a car. Public transportation also helps to reduce road congestion and travel times, air pollution, and energy and oil consumption, all of which benefit both riders and non-riders alike.
The operation of transportation determines the efficiency of moving products. The progress in techniques and management principles improves the moving load, delivery speed, service quality, operation costs, the usage of facilities and energy saving. Transportation takes a crucial part in the manipulation of logistic.
The 5 safety rules at a glance
- Disconnect completely. Meaning that the electrical installation must be disconnected from live parts on all poles.
- Secure against re-connection.
- Verify that the installation is dead.
- Carry out earthing and short-circuiting.
- Provide protection against adjacent live parts.
Keep a safe distance behind the car in front of you. Drive according to the road conditions. Reduce speed when it is raining or the road is wet. Adhere to speed limits. Use low beam headlights (never drive with parking lights) between sunset and sunrise as well as in overcast or misty weather conditions.
Accident Rates
Clearly Motorways have the least risk of any kind of accident and urban 'A' roads the highest.The Green Cross Code
- Find a safe place to cross.
- Stop just before you get to the kerb.
- Look all around for traffic and listen.
- If traffic is coming, let it pass.
- When it is safe, go straight across the road - do not run.
Road safety awareness can be increased by educating the drivers about the traffic rules and safe driving. Advertisements, banners on roads can promote the road safety awareness. Promote small programs and ask drivers to participate to know the importance of safety.
To facilitate the work of the college by assuring access to its vehicles and by assigning the limited parking space for the most efficient use. To manage and to enforce vehicular traffic and parking on the EvCC campus and satellite sites. these are the objective of traffic rules.
Some precautions to avoid road accidents are:
- Keep your eyes on the road.
- Never use your cell phone while driving and walking on the road.
- Don't change CD's.
- Never, ever drink and drive.
- Avoid construction areas.
- Follow speed limits.
- Follow the rules of the road.
- Ignore aggressive drivers.
The main aim of safety education is to provide necessary warns and precautions so that the possible accidents would be prevented. Safety education is a series of instructions and warnings that provides awareness about possible harms and injuries with an objective of minimizing injuries and their fatal consequences.
Everyone should strictly follow the traffic rules and should always drive safely with respecting the other people and vehicles on the road. One must avoid rash driving, drunken driving and jumping red lights. Wearing helmets and seat belts could highly reduce the number of causalities during an accident.
