Red vožnje je na telefonu.

Literally, red vožnje is something like order of driving/running.

In practice, it means timetable, schedule, or specifically a bus/train timetable.

It is a noun + noun structure:

• red = order, sequence, arrangement
• vožnje = of driving / of travel / of rides

So vožnje is in the genitive case, because it depends on red. This is a very common Serbian pattern:

• čaša vode = glass of water
• plan grada = map of the city
• red vožnje = timetable

Because after red, Serbian uses the genitive.

The base form is vožnja:

• nominative singular: vožnja

But in red vožnje, it changes to:

• genitive singular: vožnje

So this is not two separate main nouns standing side by side in the same form. It is a grammatical relationship: red + of travel/driving.

Je means is. It is the 3rd person singular present form of biti = to be.

So:

• Red vožnje je na telefonu.
• The timetable is on the phone.

In Serbian, the verb to be is usually expressed in sentences like this, unlike in Russian, for example.

In Serbian, na is often used for information that appears on a device, on a screen, or on a platform.

So na telefonu naturally means:

• on the phone
• available on the phone
• shown on the phone

This sounds normal when talking about digital content.

By contrast, u telefonu more literally means in the phone, and it can be used in some contexts, but it often sounds more physical or internal, like something stored inside the device. For everyday usage about seeing information on your phone, na telefonu is very natural.

Similar examples:

• na računaru = on the computer
• na internetu = on the internet
• na ekranu = on the screen

Telefonu is in the locative singular.

That is because the preposition na can take different cases, and here it expresses location:

• na telefonu = on the phone

So:

• telefon = nominative
• telefonu = locative singular after na for location

This is the same pattern as:

• na stolu = on the table
• na poslu = at work
• na internetu = on the internet

Yes. Serbian word order is more flexible than English word order.

The neutral version is:

• Red vožnje je na telefonu.

But depending on emphasis, you could also hear:

• Na telefonu je red vožnje. = The timetable is on the phone.
• Na telefonu je red vožnje, ne na papiru. = The timetable is on the phone, not on paper.

The basic meaning stays the same, but the emphasis changes.

Very often, yes. In modern everyday Serbian, telefon frequently means phone, and depending on context, that often implies a mobile phone / smartphone.

If someone says:

• Poslao sam ti to na telefon.
• Imam to na telefonu.

people will usually understand it as a mobile phone.

If needed, Serbian can be more specific:

• mobilni telefon = mobile phone
• smartfon = smartphone

But in normal conversation, just telefon is often enough.

Serbian has no articles like the or a/an.

So red vožnje can mean:

• a timetable
• the timetable

The exact meaning comes from context.

In your sentence, English would usually translate it as the timetable is on the phone, because the speaker probably means a specific timetable already known in the conversation.

Serbian relies on context, word order, and sometimes extra words to make this clear.

Yes, in many contexts raspored vožnje can also mean schedule/timetable.

But red vožnje is a very standard fixed expression for transport timetables, especially buses, trains, and similar public transport.

So:

• red vožnje = standard term for a timetable
• raspored vožnje = also understandable, sometimes a bit more general or less fixed

If you are learning the usual expression you will see on signs, websites, and station information, red vožnje is the one to remember first.

A simple pronunciation guide is:

Red VOZH-nyeh yeh nah te-leh-FOH-noo

A few useful notes:

• ž sounds like the s in measure
• nj is like the ny in canyon
• je is pronounced roughly ye

So vožnje is not pronounced like English spelling might suggest. It is closer to VOZH-nyeh.
