Essential Components of a Drive-Thru Traffic & Parking Report
Why Councils Require a Traffic Report for Fast-Food Drive-Thrus
Local councils treat fast-food drive-thrus as a unique land use category due to their capacity to generate high volumes of traffic during concentrated peak periods. Unlike a standard retail shop, the operational model of a drive-thru creates specific traffic patterns that can significantly impact the surrounding area. The unique operational characteristics, which are detailed in the history and design of drive-thrus, create these concentrated traffic patterns. Consequently, a council’s primary objective is to ensure any new development does not compromise public safety or degrade the efficiency of the local road network. Their role is to mitigate potential negative impacts on the community, from congestion and noise to pedestrian safety.
To address these concerns, councils mandate a comprehensive Traffic Impact Assessment. This professional document, often referred to as a traffic report for fast food drive thru, provides the technical data and analysis needed to demonstrate that the proposed development can operate safely and efficiently within the existing infrastructure.
The following video provides context on the traffic challenges that concern local councils:
Key Council Concerns: Queuing and Spillback
Vehicle queuing is the line of cars waiting within the drive-thru lane. The primary risk is ‘spillback,’ which occurs when this queue becomes too long and extends out of the property onto public roads. This creates a major safety hazard by obstructing through-traffic, blocking footpaths, and increasing the risk of collisions. A traffic report models worst-case scenarios during peak hours to calculate the required queue length and ensure the site plan provides sufficient on-site storage capacity to contain all waiting vehicles.
Access, Egress, and On-Site Circulation
Councils demand a meticulous assessment of how vehicles will enter (access) and exit (egress) the site. This involves ensuring that driveways are positioned to provide adequate sight distances for drivers turning onto the main road, as well as for pedestrians on the footpath. The internal layout must also be logical and safe, preventing conflicts between vehicles in the drive-thru queue, those looking for a parking space, and larger delivery or waste collection vehicles servicing the site.
Impact on Local Intersections and Road Networks
A thorough traffic report for fast food drive thru analyses the development’s impact beyond its property line, focusing on nearby intersections. Using traffic modelling software, engineers assess the anticipated increase in vehicle movements and its effect on intersection performance. This performance is often measured by a ‘Level of Service’ (LoS) grade, from A (free-flowing) to F (forced flow/gridlock). If the proposed development is projected to cause an unacceptable drop in the LoS, the council may require the developer to fund or construct road upgrades, such as new traffic signals or dedicated turning lanes, as a condition of approval.
Essential Components of a Drive-Thru Traffic & Parking Report
A successful traffic report for a fast food drive-thru is a detailed technical document, not a simple summary of car counts. To satisfy council requirements, the report must systematically address every potential traffic and parking impact the development will have on the surrounding road network. Each component is a critical piece of the puzzle, demonstrating due diligence and a commitment to safe, efficient site operation.
A comprehensive report dissects the proposal from multiple engineering perspectives, providing council assessors with the data-driven evidence they need to grant approval. The following elements form the core of a compliant report.
Traffic Generation and Peak Hour Analysis
This foundational analysis estimates the volume of vehicle trips the proposed drive-thru will generate. Consultants do not guess; we apply established traffic generation rates from official sources like the Transport for NSW (TfNSW) Guide to Traffic Generating Developments. The assessment must focus on the site’s impact during critical network peak periods, typically the weekday morning and evening commuter peaks, as well as the business’s own specific peak, which for fast food is often a weekend lunch or dinner period.
Drive-Thru Queue Length Assessment
Inadequate queue storage is one of the most common reasons for the rejection of a drive-thru DA. This assessment calculates the required on-site queueing length to prevent vehicles from spilling back onto public roads. The calculation is based on projected peak demand, average vehicle service times, and the layout of order, payment, and collection points. As a practical example, a 10-car queue requires approximately 60-70 metres of dedicated storage lane within the property boundary.
Swept Path Analysis for All Vehicle Types
Using specialised CAD software such as AutoTURN, a swept path analysis simulates the turning path of vehicles to ensure they can manoeuvre safely throughout the site. This assessment is critical for:
-
Customer vehicles navigating the drive-thru lane and parking aisles.
-
Service and delivery vehicles (e.g., 12.5m Heavy Rigid Vehicle) accessing loading bays.
-
Council waste collection vehicles servicing the site.
This analysis proves the geometric design is functional and safe for all expected users and is a core component of the traffic engineering

Car Parking Demand and Layout Compliance
The report must demonstrate that the proposed car park meets both demand and strict regulatory standards. Parking demand is calculated based on rates specified in the local council’s Development Control Plan (DCP). The physical layout, including parking space dimensions, aisle widths, ramp grades, and the provision of accessible parking spaces, must fully comply with Australian Standard AS 2890.1. A thorough assessment also allocates parking appropriately between customer and staff needs.
The Process: From Initial Briefing to Council Submission
Commissioning a traffic report for a fast food drive thru is a structured, multi-stage process designed to deliver a robust, evidence-based document for council assessment. An experienced traffic engineer acts as a vital partner in your development team, collaborating with architects and town planners to ensure the proposed design is safe, efficient, and compliant. The process is methodical, transparent, and focused on achieving a positive outcome with the local authority.
Understanding the key milestones demystifies the journey from initial concept to a submission-ready report.
Step 1: Site Inspection and Data Collection
The foundation of any credible traffic assessment is a thorough understanding of the site’s local context. This begins with a physical site inspection. Our engineers attend the site to observe existing traffic behaviours, road network characteristics, and potential constraints. This is followed by formal data collection, which includes:
-
Conducting traffic surveys to establish baseline vehicle volumes on surrounding roads, particularly during peak hours.
-
Recording existing speed limits, regulatory and advisory signage, and line marking.
-
Documenting road geometry, including lane widths, intersection types, and available sight lines from the proposed access points.
This empirical data ensures all subsequent analysis is grounded in real-world conditions, not assumptions.
Step 2: Technical Analysis and Modelling
With raw data collected, the next phase involves detailed technical analysis. We use industry-standard traffic modelling software to forecast the traffic generation of the proposed drive-thru and assess its impact on the adjacent road network. This analysis is governed by the specific requirements of the local council’s development control plan and relevant Australian Standards, such as AS 2890.1 for parking facilities. This is often an iterative process where we test various design options-such as alternative driveway locations or internal queueing configurations-to identify the optimal solution that satisfies both operational needs and council compliance.
Step 3: Report Preparation and Recommendations
The final stage is the drafting of the formal report. This document synthesises all data, analysis, and findings into a clear, logical structure that directly addresses council requirements. The completed traffic report for your fast food drive thru will present definitive findings on traffic impact, parking demand, and site access safety. Crucially, it provides clear, actionable recommendations to mitigate any identified impacts. These recommendations are supported by detailed diagrams, such as vehicle swept path analyses and sight-line diagrams, which are included as appendices to provide council with all necessary evidence for approval.
Common Design Flaws That a Traffic Report Will Identify
A professional traffic report is more than a formality for council; it is a critical diagnostic tool. Engaging an experienced traffic engineer early in the design phase allows you to identify and rectify common but costly flaws before lodging your Development Application (DA). A robust traffic report for a fast food drive thru acts as a preventative measure, saving significant time and money by avoiding council rejection and redesign requests. Consider this a checklist of critical failure points to avoid.
Inadequate On-Site Vehicle Storage (Queuing)
The most frequent cause of DA refusal for a drive-thru is inadequate on-site vehicle queuing capacity. If the queue of waiting cars spills back onto the public road network, it creates congestion and a significant safety hazard. This is often caused by a simple design error, such as placing the order speaker or collection window too close to the site entrance. This single flaw is often enough for an immediate and outright council refusal.
Poor Internal Circulation and Access
A functional site must accommodate all vehicle movements safely and efficiently. Common circulation flaws that a traffic assessment will identify include:
-
Drive-thru lanes that block access to dedicated parking spaces, preventing customers from parking.
-
Turning radii that are too tight for service and delivery vehicles, which is confirmed through a vehicle swept path assessment.
-
Insufficient space for vehicles to safely pass a stopped or broken-down car in the queue without disrupting the site’s operation.
These complex interactions are often best visualised. See examples of complex sites we’ve assessed in our videos section.
Non-Compliant Parking and Ramp Design
All parking facilities, including access ramps and individual bays, must strictly adhere to Australian Standards (AS 2890.1). A traffic engineering assessment will verify compliance on critical details that are often overlooked, such as correct ramp grades, appropriate dimensions for parking bays, and the provision of safe, clearly marked pedestrian routes. Failure to meet these standards will result in a non-compliant design and a failed DA. Identifying these issues pre-lodgement is a fundamental part of the traffic assessment process.
Selecting the Right Traffic Engineering Consultant
The success of your development application hinges on the quality and credibility of your supporting documentation. Choosing the right partner to prepare your traffic report for fast food drive thru is a critical step that directly influences council assessment and approval timelines. A qualified consultant provides more than just a document; they provide a strategic advantage. The correct choice ensures your project is represented by a robust, defensible, and compliant traffic impact assessment.
Verify Their Experience with Fast-Food Developments
Not all traffic engineering experience is relevant. It is essential to engage a consultant with a proven history in the Quick Service Restaurant (QSR) sector. This specific experience ensures they are familiar with the unique operational characteristics of drive-thrus, from vehicle queuing and swept path analysis to peak hour traffic generation. Ask to see a portfolio of similar projects or case studies. A consultant with deep QSR experience understands council expectations for a traffic report for fast food drive thru, minimising requests for further information.

Ensure They Have Local Council Knowledge
Traffic codes and development assessment criteria vary significantly between local government areas. A consultant with established experience in your project’s specific council jurisdiction is invaluable. They possess an understanding of local planning schemes, engineering standards, and the unwritten preferences of council officers. This local knowledge allows for the proactive identification and resolution of potential issues, streamlining the application process and preventing costly delays. An established relationship with council engineers facilitates more efficient communication and negotiation on your behalf.
Look for Direct Access and Clear Communication
When you have a question, you need to speak directly to the expert handling your project.

Frequently Asked Questions
How much does a traffic report for a fast-food drive-thru cost?
The cost for a traffic report is determined by project complexity, site location, and specific council requirements. For a standard fast-food drive-thru, professional fees typically range from A$3,000 to A$6,000 + GST. This scope covers the necessary traffic counts, queuing analysis, parking assessment, and preparation of the formal Traffic Impact Assessment (TIA). Sites on state-controlled roads may incur higher costs due to more stringent reporting requirements and authority liaison, which we manage on your behalf.
How long does it take to prepare a traffic report for a DA?
Our standard timeframe for the preparation of a comprehensive traffic report for a Development Application (DA) is approximately two to three weeks. This period allows for essential on-site data collection, including traffic and parking surveys, followed by detailed analysis and report compilation. We work efficiently to meet project deadlines. If your submission is urgent, please contact us directly to discuss the potential for an expedited service, which is subject to the project’s scope.
What happens if the council requests changes to the traffic report?
It is common for councils to issue a Request for Information (RFI) seeking clarification or amendments to a submitted report. Our service includes managing this process. We will professionally analyse the council’s feedback, undertake any necessary revisions to the traffic assessment, and prepare a formal response that addresses each point raised. This hands-on management ensures compliance is achieved and minimises potential delays in the DA determination process, leveraging our extensive experience with council procedures.
Is a traffic report still needed for a small coffee shop with a drive-thru?
Yes, a traffic report is a standard requirement for any development that includes a drive-thru facility, irrespective of its scale. Even a small coffee shop generates new vehicle movements and has specific operational needs for vehicle queuing and safe site access. The council must assess these impacts to ensure the proposal does not adversely affect road safety or local network efficiency. The scope of the report may be simpler, but the requirement for a professional assessment remains.
Can a good traffic report guarantee my development application will be approved?
A high-quality, comprehensive traffic report is a critical component for a successful DA, but it cannot guarantee approval on its own. The council’s final decision considers numerous factors, including town planning, environmental impacts, and public submissions. However, a robust report that professionally resolves all traffic, parking, and access issues significantly strengthens your application. It demonstrates due diligence and compliance, systematically addressing potential grounds for refusal related to traffic engineering matters.
My site is on a main road. Does this make getting approval harder?
A location on a main road, or a state-controlled road, introduces additional complexities but does not inherently make approval more difficult. It simply necessitates a more detailed and rigorous assessment. The traffic report for a fast food drive thru on such a road must meticulously analyse impacts on traffic flow, intersection performance, and road safety. It will also likely require direct liaison with state road authorities. Our extensive experience with these authorities ensures all specific requirements are met.
