What is temporary traffic management and when is it mandatory?

Temporary Traffic Management (TTM) is a system of measures, technical equipment, and rules that temporarily change the traffic flow on a given road section to ensure safety during construction, maintenance, or emergency activities.

It is a mandatory element for any intervention in the road infrastructure and is directly related to the safety of drivers, pedestrians, and site workers. 🚧

Definition: what does temporary traffic management include?

TTM covers:

• temporary vertical signaling (road signs);

• temporary horizontal marking;

• light signaling;

• portable traffic lights;

• safety fences and barriers;

• cones, bollards, and guiding elements;

• temporary routes and diversions.

The primary goal of temporary traffic management is controlled and safe passage through a zone with altered traffic conditions.

In which cases is temporary management mandatory?

In Bulgaria, temporary traffic management is required for:

1️⃣ Road repair and rehabilitation

• resurfacing;

• milling;

• pavement repair;

• curb replacement.

2️⃣ Construction and installation activities

• construction of water and sewerage networks;

• cable laying;

• installation of underground infrastructure.

3️⃣ Emergency situations

• burst water pipes;

• pavement subsidence;

• emergency repairs.

4️⃣ Private sites with access to a public road

• construction in urbanized areas;

• logistics bases;

• industrial zones.

Why is temporary management critically important? ⚠️

1. Accident prevention

The most common accidents in roadwork sections are due to:

• lack of clear signage;

• sudden lane changes;

• unexpected obstacles.

Properly designed TTM:

• provides sufficient reaction time;

• reduces the risk of traffic accidents;

• protects workers on site.

2. Legal responsibility

In the absence of an approved temporary organization:

• the contracting authority bears administrative responsibility;

• fines may be imposed;

• construction activities may be suspended;

• in the event of an accident – serious liability for damages.

3. Traffic control and minimizing congestion

Well-planned temporary management:

• optimizes throughput capacity;

• reduces chaos;

• prevents secondary accidents;

• maintains the functionality of the road network.

How is a temporary traffic management project prepared?

The process involves several key steps:

📐 1. Site Analysis

• traffic intensity;

• road type;

• speed limits;

• proximity to schools, hospitals, or residential areas.

📝 2. Scheme Preparation

The project includes:

• placement of signs;

• designation of diversions;

• positions of barriers;

• markings and lighting devices.

🏛️ 3. Coordination and Approval

The project is subject to approval by:

• the respective municipality;

• RIA (for national roads);

• the Ministry of Interior authorities (Traffic Police).

Implementation of temporary traffic management is impermissible without official approval.

Key elements of effective TTM

✔️ Clear Visibility

Signs must be:

• highly reflective;

• correctly positioned;

• visible in night conditions.

✔️ Consistency

The driver must receive information in stages:

1. warning;

2. restriction;

3. guidance;

4. passage.

✔️ Physical Separation

For higher risk, the following are used:

• concrete barriers;

• mobile railings;

• safety barriers.

Temporary vs. Permanent Traffic Management

Temporary traffic management must be clearly distinguishable from permanent management to avoid confusion.

Common mistakes in temporary management ❌

1. Insufficient reaction distance.

2. Lack of sign repetition.

3. Overly complex schemes.

4. Use of unsuitable materials.

5. Lack of night signaling.

These mistakes significantly increase the risk of accidents.

TTM in urban environments – specifics

In populated areas, the following must be considered:

• pedestrian flows;

• bicycle lanes;

• public transport;

• access to commercial sites.

Special attention is required in:

• school zones;

• hospitals;

• high-traffic intersections.

What does the investor gain from professional execution?

✅ Reduction of the risk of sanctions
✅ Faster project completion
✅ Fewer accidents
✅ Better public reputation
✅ Lower insurance risks

Temporary traffic management is not a formality – it is a risk management tool.

Conclusion

Temporary traffic management is an essential part of any construction or repair activity affecting road infrastructure.

It guarantees:

• safety;

• legal compliance;

• project efficiency;

• protection of all road users.
