Traffic engineering and street lighting

To avoid chaos: traffic technology regulates, controls and influences the flow of traffic.

Well-organized traffic
Go with the flow

In traffic engineering, traffic concepts and traffic guidance systems are developed for both passenger and freight traffic. Traffic operations are organized and the flow of traffic is controlled and optimized by using intricately synchronized traffic signal and parking guidance systems. Efficient street lighting is also a part of traffic engineering, increasing the safety of all road users.

Frequently asked questions about traffic engineering

What is the purpose of traffic signals (traffic lights)?

Traffic signals are used to control the flow of traffic.

How do traffic signals control traffic?

Controlled light signals, which differ in shape and color, provide road users with appropriate rules of behavior.

Which set of rules is the control of traffic signals based on?

In Germany, control is regulated according to the technical regulations “Richtlinien für Lichtsignalanlagen” (RiLSA).

How do the circuits of the traffic signals differ?

The intervals are defined in a signal time schedule or are implemented depending on the volume of traffic, e.g. varying according to day, night, peak times, or on request.

How does public transport obtain a preferred right of way?

So-called priority circuits enable public transport to be given priority over other road users at traffic signals, depending on the timetable.

How do parking guidance systems work?

By counting the vehicles entering and leaving a parking lot, a system calculates the number of free spaces and transmits this information to a computer, making it available to road users or displaying it directly. Dynamic parking guidance systems are adapted to the flow of traffic in cities and guide road users accordingly.

What components are streetlights made of?

Street lights usually consist of a housing, a translucent cover, control gear such as ballasts and igniters, optical systems such as mirrors, and light sources. In some cases, they are fed locally via photovoltaic systems and contain the corresponding components.

How is street lighting managed?

Street lighting can be switched on and off centrally or decentrally via a twilight switch. Other options include the use of audio frequency or radio ripple control technology, timers, calls, or messaging. Gas lighting is usually operated via remote gas ignition.

How is the power supply of street lighting ensured?

In most cases, street lighting is connected via a separately laid lighting cable. This is connected to the general power supply via a switch box, which often supplies several streets.
