Introduction to Intelligent Parking The Intelligent Parking System is ideal to be installed in a wide range of parking facilities. While these facilities vary widely, it is possible to engineer, supply and commission a tailored Intelligent Parking System by making a few decisions, and then selecting the appropriate components from the enclosed lists, and in this way have a “kit” of components and drawings that a competent electrician and IT installer will be able to install without difficulty.

The decisions to be made prior to implementation include…
1) Source of parking data 2) Data Concentrators 3) Signs 4) Central Computer system 5) Advanced features
Rev 0.4 Page 3 of 7
Source of Parking Data Intelligent Parking can source parking data from one or more of the following sources of data
a) Indoor ultrasonic sensor, with LED indicators. These sensors are suitable for indoor use, where there is a roof over the parking bay. These sensors combine high reliability of detection, as well as LED indicators (Red/Green/Blue/Amber) to indicate the status of the bay.
b) In/Out loop counter. These loop sensors provide the capability to count vehicles entering or exiting a parking zone, which enables parking availability to be shown on electronic signs.
c) Interface with cash management systems. A number of the Cash Management systems provide an interface for retrieving the number of available bays, based on the cash management system ingress/egress counts. Intelligent Parking can retrieve these counts, aggregate them appropriately, and display the resulting information.
d) Outdoor individual bay count sensor (under development). For the ultimate in reliability, coming soon from Intelligent Parking is the wireless individual bay count sensor.

Data Concentrators The appropriate selection of the position and quantity of the Intelligent Parking Data Concentrators is a key part of designing a successful system. Data Concentrators should be positioned as follows:
a) One data concentrator for a maximum of 72 individual sensors. Each data concentrator should be responsible for a “zone” of parking bays.
b) Each data concentrator can drive a “zone board” electronic sign. The zone board directs traffic down a particular aisle to a parking zone. (see details under signs).
c) Each data concentrator can monitor up to 8 loops for ingress/egress, for loop data source.
d) Data Concentrators can be provided complete with power supplies and enclosures, ready for installation, or as bare printed circuit assemblies, with software, ready to be mounted in a cabinet.

e) Data Concentrators provide an NTCIP standard interface to the central system, for the Zone Display Board as well as for the parking information.

Signs Any size and type of NTCIP sign is supported by Intelligent Parking. This includes large electronic signs, suitable for Incident Management, through to small electronic parking guidance signs. Signs should be selected based on:
a) Character height (1/500 of the viewing distance will suit in most instances) b) Number of characters.
The most economical signs are combination fixed signs, with electronic four- character elements, as shown in the attached photographs. The optimal sign selection will guide the driver from the freeway, though which parking lot to select, then which floor to select, then which aisle to select, and finally to the open bay.

As the driver approach the parking garage, signs guide the driver on which floor to park. Once inside the floor, an aisle board and zone board guide the driver in which aisle to park.

Typically, the Intelligent Parking kit will be provided with the electronic message elements, to make up the required signs, which can be mounted in the fixed signage by a local sign supplier. Alternatively, local supply of NTCIP signs can be arranged to interface with Intelligent Parking. Central Computer System The Central Control System at the heart of Intelligent Parking can range in complexity between:
a) a simple, single server system where the system aggregates the parking data, and displays the appropriate messages on the signs.
b) a more complex client-server system, incorporating elements of traffic management such as incident management, response plans, traveler information, and WEB interfaces.
The Intelligent Parking software is part of the Intelligent Control suite of traffic applications, which covers the broadest range of traffic and parking applications. Appropriate site licenses are issues, and the software configured appropriately, to provide a broad range of functionality over and above the basic parking engine. Reports are a key part of Intelligent Parking, and a range of standard real-time, status, and historical reports are available. Custom reports are added at commissioning, to suit the user needs. For further detail, see the Intelligent Parking specification and User Guide. Advanced Features A range of optional and advanced features are available with Intelligent Parking, including:
a) Intelligent Reservation: A WEB based reservation system, which allows a premium to be levied for a guaranteed reservation (Johannesburg Phase 3 – details to follow)
b) Installation under occupation: A set of gantries, and method statement, was developed to allow the installation of Intelligent Parking to take place while the car park was in use. The experience gained in this approach is available if required.
c) Intelligent Control, Intelligent Incident and Intelligent Maintenance are companion applications to Intelligent Parking, and are designed to operate as a suite of applications if Advanced Traffic Management is required..
Example kit of materials A typical set of materials and services that will make up Intelligent Parking for, say, a 10,000 bay multi-story parking garage will be as follows:
