Car Parks

1. Definition and Functional Role

A car park is a dedicated open-air area or building equipped with parking bays for motor vehicles, serving as a core component of the urban static transport network. Its fundamental role is to provide vehicle parking space to alleviate road traffic congestion, while functioning as an essential supporting facility for urban transport hubs, commercial developments, and sports and recreational venues, playing a pivotal role in linking different modes of commuting and maintaining smooth urban mobility.

2. Classification

Car parks are mainly categorised by their location and target users as follows:

Category	Type	Key Characteristics
Location	On-street parking (Kerbside)	Located along road kerbsides for short-term temporary parking, structured to avoid obstructing traffic flow and lines of sight
	Off-street car park	Dedicated areas located away from main carriageways for longer parking durations, available in various formats
Target Users	Public car park	Commercial facilities developed under urban planning schemes and open to all motorists
	Private / Reserved car park	Designated for internal use by specific organisations or residential developments, generally not accessible to the public
Structural Format	Open-air surface car park (Ground-level)	Requires a larger land footprint, provides easy vehicle entry and exit, and organises bays and access lanes via road markings
	Basement car park	Built beneath public parks, roads, or commercial plazas to maximise ground-level space, involving higher construction complexity and development costs
	Multi-storey car park (MSCP)	Multi-level parking structure offering high land-use efficiency, available in conventional ramp-access or automated mechanical layouts
Operating System	Self-drive / Conventional car park	Drivers manually navigate in and out, covering ramped multi-storey and basement layouts with relatively lower build and operating costs
	Automated mechanical car park	Uses automated car stackers, traversers, and rotary lifts to park and retrieve vehicles, delivering high space efficiency at a higher capital cost

3. Internal Traffic Flow and Safety Infrastructure

Internal operations within a car park rely on traffic signboards, speed calming measures, and clear directional markings to maintain safe traffic flow. Speed mitigation measures typically include speed limit signages (strictly capped at 30 km/h or below), speed bumps, transverse rumble strips, and chevron alignment markers on bends. For smart car park management, modern facilities are widely integrated with automated ticketing systems, 24/7 CCTV surveillance, and fire alarm networks, while entry and exit points increasingly use Automated Number Plate Recognition (ANPR) and cashless/contactless payment systems.

4. EV Facilities and Emergency Management

With the rapid uptake of electric vehicles (EVs), car parks must provide dedicated EV charging bays (with new public developments required to allocate at least 10% of total bays for EV charging), supported by comprehensive safety protocols. EV charging zones in basement car parks require physical fire separation—divided into independent fire compartments by firewalls with a minimum 2-hour fire-resistance rating, adequate spacing between zones, and equipped with water-based fire extinguishers, fire blankets, dedicated sprinkler systems, and AI-enabled smoke detection. Car park operators must establish emergency response SOPs covering fire, flash floods, on-site accidents, and service shutdowns; in the event of severe risks like EV battery thermal runaway, immediate evacuation protocols must be triggered and the fire department (Bomba) alerted without delay.

5. Future Trends

Smart Car Park Management: Leveraging IoT and cloud data platforms for real-time bay reservations, automated 'Find My Car' locators, seamless barrierless payments, and dynamic digital wayfinding. Some urban areas have also implemented high-mount camera enforcement, wireless in-ground geomagnetic sensors, and satellite positioning for kerbside parking.
Vertical and High-Density Utilisation: Multi-tier automated parking systems are advancing towards faster retrieval times and fully robotic operation, while major commercial developments are increasingly integrating car parks with Park & Ride (P+R) public transit hubs.
Upgraded Safety Benchmarks: For basement car parks and high-voltage charging zones, stricter fire-compartment regulations, dedicated emergency power cut-off switches, and AI early-hazard detection systems are progressively becoming mandatory operational standards.
