1. What is an Access Strategy?
An Access Strategy is the "rule set" that defines the behavior of your parking access. It determines:
-
Booking requirements: Do you need to reserve in advance?
-
Guarantees: Is a spot promised to you or depends on live availability?
-
Tracking: How does the system monitor your session (In/Out status)?
In short, it shapes both the User Experience and the Capacity Logic of the parking lot.
2. Quick Comparison Table
| Strategy | Need to Book? | Guaranteed Spot? | Best Use Case |
| PREF (Preferential) | No | ✅ Yes | VIPs, Residents, or Critical Staff. |
| BOOK (Booking) | Yes | 🔶 If Booked | Hybrid work, shared offices, and fairness. |
| FCFS | No | ❌ No | Spontaneous parking based on live availability. |
| OTFB (On-the-fly) | No* | ❌ No | On-demand parking with a set end-time. |
| Visitor | No* | 🔶 Varies | Guests, contractors, and temporary visits. |
| Free-to-Pass (FTP) | No | ❌ No | Delivery or pass-through (no parking spot). |
OTFB requires selecting a duration upon entry. Visitor access is pre-created by an Admin
3. The Strategy Guide
Preferential (PREF)
-
-
User View: No action required before arrival. Simply go to Access in the app and select Enter.
-
Admin View: Assign this to users who require 100% availability. Note: PREF consumes "guaranteed" capacity 24/7 or during set hours.
-
Booking (BOOK)
-
-
User View: You must reserve your spot via the App or Web. Access is only granted during your specific booking window.
-
Admin View: Use this to manage limited capacity fairly. You define the booking rules (how far in advance a user can reserve).
-
First Come First Served (FCFS)
-
-
User View: No reservation needed. Access depends purely on whether the "Spots Left" counter is above zero when you arrive.
-
Admin View: Ideal for maximizing occupancy. Ensure your exit detection is reliable so the "Spots Left" counter stays accurate.
-
On-The-Fly Booking (OTFB)
-
-
User View: At the gate, the app will ask: "How long will you stay?". You select a duration to begin your session.
-
Admin View: Best for time-limited sessions. It forces the user to declare an end-time, helping you predict upcoming availability.
-
Vehicle-based Strategies
-
-
User View: Access is linked to the Vehicle/License Plate rather than your individual profile. Often used for car-sharing or fleet vehicles.
-
Admin View: Prevents entitlement conflicts when multiple people share the same fleet of cars.
-
4. Troubleshooting: Why is access unavailable?
| What you see | What it means | Recommended Action |
| "No spots left" | The parking is at maximum capacity. | User: Wait for a spot or use an alternative. Admin: Review the PREF/BOOK mix. |
| "0 credits left" | You have exhausted your monthly allowance. | User: Contact your Admin. Admin: Check the user's credit renewal policy. |
| "Outside timetable" | You are attempting access during restricted hours. | User: Check your access rights. Admin: Verify the Access Policy schedule. |
| "Sequence error" | The system thinks you are already inside. | User: Ensure you "Exit" correctly. Admin: Check if the user missed an exit log. |
5. Understanding "No Re-entry" (ASE)
Access Sequence Enforcement (ASE) is a security rule that prevents "double entries."
-
The Rule: You cannot enter the parking if the system thinks you are already inside.
-
The User Impact: If you entered but didn't register an "Exit" (manually or via sensor), your next entry will be blocked.
-
Solution: Always ensure your exit is registered. If blocked, contact your internal parking administrator.
6. Critical Warning: Before Changing Strategies
⚠️ Important: Changing an Access Strategy can have immediate side effects on your parking occupancy.
-
Switching BOOK to FCFS: You lose the ability to plan ahead. Users who previously relied on reservations may find the parking full upon arrival.
-
Adding more PREF users: This reduces the pool of spots available for everyone else.
-
Enabling ASE: This requires very high exit-logging reliability. If your exit sensors are down, enabling ASE will block many users.
💡 Pro-Tip: Before making a major strategy change, contact your Izix Account Manager to validate the impact on your specific spot groups.
7. Frequently Asked Questions (FAQ)
Q: Which strategy is best for hybrid work?
A: BOOK is usually best. it ensures fairness and allows employees to plan their commute with certainty.
Q: Why do I get "Access sequence not respected"?
A: The system believes your last action was an entry. You must register an "Exit" before the system allows you to enter again.
Q: When should we use Free-to-Pass?
A: Only for users who need to open the gate but will not park (e.g., a delivery truck or a car dropping someone off).
