The first right-side commercial entries along the Alsancak Coastal Axis activate almost immediately after the Karaoğlanoğlu roundabout exit. The distance between circular flow and first turning intention is shorter than most drivers anticipate.

This creates a signaling delay.

Inside the roundabout, attention is absorbed by yielding and exit alignment. Once westbound steering stabilizes, drivers often shift from navigation mode to destination mode. The decision to turn right into a fuel station, retail forecourt, or side connector forms only after exit completion.

The indicator is activated late.

Time pattern: 17:00–19:30 weekdays. Secondary concentration: 12:00–14:00 Saturdays.

During these hours, westbound vehicles leave the roundabout in moderate sequence. Spacing is reduced but not congested. Within 80 to 150 meters, a driver intending to enter a commercial access point realizes proximity and initiates deceleration before fully signaling.

The following vehicle, still completing acceleration rebuild, interprets forward motion as continuity. The brake application appears abrupt because the indicator cue arrives simultaneously or fractions of a second afterward.

A common local sequence unfolds along the Alsancak main strip:

Vehicle A exits the roundabout and accelerates moderately.
Vehicle B follows at rebuilt corridor speed.
Vehicle A recognizes a right-side retail entrance and begins braking.
Indicator activation occurs during deceleration rather than before it.

The compression that follows is not caused by high speed. It is caused by sequence inversion. Signaling is expected before speed reduction. When that order reverses, reaction time narrows.

Alsancak’s corridor differs from Karaoğlanoğlu in interruption density. Retail clustering begins earlier and occurs more frequently. The cognitive shift from circular discipline to commercial anticipation must happen faster.

Historically, when access points were fewer, late signaling had lower consequence. With intensified frontage development through the 2000s and 2010s, each omitted or delayed indicator now intersects with closer following distances.

Evening conditions add subtle pressure. Westbound glare during certain months reduces peripheral detection of flashing indicators. Illuminated shop signage competes visually with signal lights, especially in the 19:00 to 20:30 window.

The structural seam is clear:

Circular focus
Exit stabilization
Late destination recognition
Brake-before-indicator sequence

The road does not announce the need for immediate decision.

Alsancak Axis requires intention clarity within seconds of roundabout release. When signaling is postponed until the vehicle is already slowing, the corridor compresses without warning.

The omission is small.
The timing effect is structural.
