Elements of streets and roads: a complete guide to the design and standards of

Road infrastructure is a complex system where each element performs a strictly defined function. Not only the comfort of drivers and pedestrians, but also the level of accidents on the site depends on the quality of design and compliance with standards. For example, improperly designed shoulder may cause an accident during a forced stop, and the lack of tactile tiles on the sidewalk creates risks for people with disabilities.

In this article we will look at everything in detail elements of streets and roads, their classification by GOST R 52766-2023 and SNiP 2.07.01-89*, as well as typical mistakes that are made when arranging. We will pay special attention to the questions that most often arise among car owners: is it possible to park on dividing stripwhat are the requirements for bike paths, and why curbs on some streets it is higher than the standard 15 cm. The material will be useful both for drivers and for those who plan to build or reconstruct a road on their site.

1. Roadway: main elements and standards

The roadway is the only element of the road intended for the movement of vehicles. Its width, coverage and markings are strictly regulated. For example, for main roads the width of one lane must be at least 3.75 m, and for local streets it is allowed 3.0 m. At the same time edge of the roadway (border with the roadside) must be marked with markings 1.2.1 or 1.2.2.

Important nuance: the roadway may include dedicated lanes for public transport (indicated by markings 1.23.3 and sign 5.14). Only buses, trolleybuses and minibuses are allowed to operate on such lanes. Penalty for violation - 1 500–3 000 ₽ (Part 1.1 of Article 12.17 of the Administrative Code).

• 🚗 Lanes: minimum width - 3.0 m, optimal - 3.5–3.75 m. On curved areas the width increases by 0.5–1.0 m.
• 🛣️ Dividing stripes: Mandatory on roads with 4+ lanes. Width - no less 2.0 m (on highways - 6.0 m).
• 🔄 Crossroads: Curb radius - minimum 8.0 m (for trucks).
• 🚧 Safety islands: located at pedestrian crossings with a width > 6.0 m.

⚠️ Attention: If there are no markings on the road, the width of the lanes is determined based on the actual condition of the surface. For example, on a two-lane road without markings, the left half is reserved for oncoming traffic, even if it is already on the right.

2. Curbs: purpose, width and rules of use

The curb is side of the roadadjacent to the roadway. It is intended for:

• 🚘 Stops and parking (if there are no prohibiting signs).
• 🚶 Pedestrian movements in the absence of a sidewalk.
• 🚜 Special transport passages (tow trucks, municipal equipment).
• 🛠️ Emergency stop if the car malfunctions.

By GOST R 52398-2005, minimum shoulder width:

Road category	Minimum curb width (m)
Main roads (I–II categories)	3,75
Public roads (III category)	2,5
Local streets (IV–V categories)	1,5
Bike paths	1.0 (each side)

Important: on the roadside prohibited:

• 🚫 Movement of mechanical vehicles (except for cases provided for by traffic regulations).
• 🚫 Long-term parking (> 5 minutes) without the emergency signal on.
• 🚫 Placement of advertising structures closer 5.0 m from the edge of the roadway.

3. Sidewalks and pedestrian areas: safety requirements

The sidewalk is element of the road intended exclusively for pedestrians. Its width depends on pedestrian flow intensity:

• 🏙️ In the city center (high load) - minimum 2.25 m.
• 🏘️ In residential areas - 1.5 m.
• 🛒 At shops and bus stops - 3.0 m (taking into account crowds).

Required sidewalk elements:

• 👣 Tactile tiles for the visually impaired (installed at all pedestrian crossings since 2016).
• 🌳 Green spaces (trees are planted no closer 0.75 m from the edge of the sidewalk).
• 🚮 Urns (the distance between them is no more 100 m).
• 💡 Lighting (lighting standard - 10–20 lux).

⚠️ Attention: The fine for parking on the sidewalk in Moscow and St. Petersburg is 3 000 ₽, in the regions - 1 000 ₽ (Part 3 of Article 12.19 of the Administrative Code). Exception - signs 6.4 + 8.6.2–8.6.9permitting parking on the sidewalk.

What to do if the sidewalk is occupied by parked cars?

If the sidewalk is blocked, you have the right to call a tow truck through the Moscow Parking app or call 3210 (in St. Petersburg - 575-77-77). You can also contact the traffic police with a photograph of the violation through the State Services portal.

4. Dividers and islands: when to install them

The dividing line is structurally separated road element, which separates oncoming traffic flows. It could be:

• 🌿 Green (lawn, shrubs).
• 🧱 Reinforced concrete (on highways).
• 🟡 Temporary (plastic fencing during repairs).

Traffic islands (at pedestrian crossings) and traffic islands (at intersections) are also partitioning elements. Their key features:

Island type	Purpose	Minimum size (m)
Safety island	Pedestrian protection on wide crossings	1,5 × 1,5
Guide island	Adjusting flows at intersections	3,0 × 1,0
Dead-end island	Preventing driving into oncoming lanes	2,0 × 0,5

On dividing strips prohibited:

• 🚗 Movement and stopping of the vehicle (fine - 500 ₽).
• 🚶 Pedestrian crossing (except for specially equipped places).
• 📦 Advertising or trading.

5. Bicycle and pedestrian paths: norms and conflicts

Bicycle paths (bike paths) and pedestrian and bicycle zones (bicycle and pedestrian paths) have become an essential element of modern infrastructure. Their key differences:

• 🚴 Bike path:
  • Indicated by the sign 4.4.1 and markings 1.24.1.
  • Width - minimum 1.5 m (for two-way traffic - 2.5 m).
  • Pedestrian traffic prohibited (fine - 500 ₽).
• 🚶🚴 Bike and pedestrian path:
  • Indicated by the sign 4.5.2–4.5.7.
  • Width - minimum 2.5 m (divided into zones).
  • Pedestrians and cyclists move separately.

Frequent conflicts arise due to:

• 🚶 Pedestrians on bike paths (especially near parks and schools).
• 🚗 Car parking in bike lanes (fine - 2 000 ₽).
• 🛴 Electric scooters, which according to traffic regulations are equivalent to bicycles, but often ride on sidewalks.

6. Road signs and markings: how they interact

Road signs and markings are visual information system, which regulates movement. Priority has:

1. 🔴 Temporary signs (on a yellow background).
2. 🟡 Permanent signs.
3. ⚪ Marking (if it does not contradict the signs).

Examples of conflicts and their resolution:

Situation	What's more important?	Penalty for violation
Sign 3.20 (“Overtaking is prohibited”) and markings 1.5 (broken line)	Sign	5,000 ₽ or deprivation of rights
Sign 5.15.1 (“Direction of lanes”) and markings 1.18 (arrows)	Sign	500 ₽
Temporary sign 4.1.1 (“Move straight ahead”) and permanent markings 1.1 (solid line)	Temporary sign	1 000–1 500 ₽

Pay special attention horizontal markings:

• 🟡 1.1 (solid) - cross prohibited.
• 🟢 1.2.1 (edge of the roadway) - allows stopping.
• 🔵 1.23 (letter "A") - lane designation for route vehicles.

7. Curbs, parapets and fences: hidden functions

Borders and fences are not only decorative, but also protective function:

• 🛡️ Borders 15–20 cm high prevent cars from driving onto the sidewalk.
• 🏗️ Parapets (on bridges and overpasses) are designed for impact loads up to 100 kN.
• 🚧 Metal fencing in dangerous areas absorb impact energy.

Requirements for curbs GOST 6665-91:

• Height: 15–20 cm (for highways - up to 25 cm).
• Top width: minimum 5 cm.
• Material: grade concrete B22.5 or granite.

⚠️ Attention: On some streets the curbs are specially made higher (25–30 cm) to prevent parking on the sidewalk. Such borders are called "anti-parking" and are installed near schools, hospitals and pedestrian areas.

8. Lighting and drainage: invisible but critical elements

High-quality lighting and drainage system directly affect road safety. Illumination standards according to SNiP 23-05-95:

• 🌃 Main roads: 20–30 lux.
• 🏙️ City streets: 10–20 lux.
• 🚶 Pedestrian areas: 10 lux.

The drainage system prevents water from accumulating on the roadway. Its key elements:

• 💧 Trays (laid along the road with a slope 0,005–0,01).
• 🕳️ Storm water inlets (the distance between them is 40–60 m).
• 🌊 Wells (depth - no less 1.5 m).

If the drainage fails, water will form on the road. puddles and ice crusts, which leads to:

• ⚠️ Increased braking distance by 30–50%.
• ⚠️ Risk of aquaplaning at speed > 60 km/h.
• ⚠️ Formation of holes after frost.

FAQ: Frequently asked questions about road elements

Is it possible to park on the median?

No, the median strip is intended only to separate traffic flows. Parking there is punishable by a fine. 500 ₽ (Part 1 of Article 12.19 of the Administrative Code). Exception - markup 1.1 (solid line) width < 2.0 m, but even in this case, parking is allowed only if there is a sign 6.4.

What is the minimum sidewalk width for wheelchairs?

By SP 59.13330.2016, the minimum width of the sidewalk for wheelchairs is 1.8 m. In this case, the slope should not exceed 5% (or 8% on short sections with handrails).

What to do if there are no markings on the bike path?

If the bike path is not marked, but there is a sign 4.4.1, it still works. Pedestrian traffic on such a path is prohibited. If the markings are erased, focus on the physical compartment (curb, lawn).

Is it possible to drive on the side of the road if the roadway is busy?

Driving on the side of the road is permitted only in cases stipulated by the traffic rules (clause 9.9): during a forced stop, around an obstacle, or as directed by a traffic controller. In other cases, this is punishable by a fine. 1 500 ₽.

Who should clear the snow from the sidewalk: homeowners or the city?

By Housing Code of the Russian Federation (Article 161), cleaning sidewalks is the responsibility of management companies or HOAs. In Moscow and St. Petersburg, home owners face fines of up to 50 000 ₽.
