ALSANCAK CORRIDOR – EVENT VENUE EXIT SURGE NEAR BEACH ENTRANCES

Along the western stretch of the Alsancak Corridor, several beach entrances and event venues sit directly off the coastal road without deep internal buffering. When an event ends, discharge is not gradual.

It is simultaneous.

Time pattern: 22:00–23:30 during summer events. Secondary window: 18:00–20:00 for sunset gatherings.

Unlike café clustering, which disperses across multiple frontage points, venue exits concentrate at one primary gate. Dozens of vehicles prepare to rejoin the corridor within a short window.

A typical sequence unfolds:

Event ends.
Vehicles queue inside the venue access road.
The first few cars merge westbound successfully.
Following vehicles accelerate more assertively to avoid internal stacking.
Through-traffic encounters repeated merge attempts within 60 to 120 seconds.

The corridor rhythm fractures.

Because beach entrances are visually open during daylight, drivers underestimate nighttime merge density. Internal parking areas often lack signal coordination with the main road. Each vehicle must individually judge gap timing.

Compounding this, some drivers attempt eastbound turns across westbound flow immediately after exit. Without a protected median refuge, staged crossing occurs under pressure.

Historically, as beachfront venues expanded and seasonal events increased through the 2010s and into the 2020s, peak discharge windows intensified. The coastal road geometry remained linear, without formal acceleration lanes.

Lighting conditions worsen spatial judgment. Headlights from queued vehicles inside the venue shine outward toward the corridor, reducing contrast for approaching drivers. Brake lights stack visually, making it difficult to assess which vehicle will move next.

The structural seam forms under four simultaneous pressures:

Synchronized multi-vehicle discharge
No acceleration buffer
Continuous through-traffic
Cross-direction turning attempts

The risk is not high speed. It is concentrated merge density within a narrow time band.

At event close, the Alsancak Corridor does not absorb vehicles gradually.

It absorbs them in waves.
