Route Planning

Introduction

Route planning turns a transport or service job into a practical sequence of movements, stops, times, and decisions. In vocational work, you may plan a delivery round, a technician visit schedule, a passenger service, a construction supply run, a field-service tour, or another journey with several requirements. A useful plan is not simply the shortest line on a map. It must be safe, feasible, efficient, and suitable for the job.

A route planner can compare possible paths between locations using criteria such as distance, travel time, cost, or other constraints. In professional practice, you also need to consider customer time windows, loading and unloading time, vehicle dimensions and capacity, road restrictions, traffic, breaks, workplace procedures, and a backup plan.

The image shows a digital route calculation between an origin and a destination. A professional route plan adds operational information that a simple line on a map may not contain.

This video introduces route planning in a transport company and highlights the many factors that dispatchers consider.

Learning Goals

By the end of this aiMOOC, you should be able to read a route-planning brief, identify hard and soft constraints, check map and location data, estimate route time, compare route alternatives, select a feasible stop sequence, use digital navigation tools critically, react to disruptions, and communicate a route plan clearly.

You will connect practical planning with Logistics, Map reading, GPS, GIS, Graph theory, Dijkstra's algorithm, vehicle routing, Operations research, and workplace safety.

Route Planning in Vocational Work

A professional route plan answers four basic questions: Where must you go? In what order? When must each activity happen? What conditions must be respected? The answers depend on the job. A courier may prioritize delivery windows. A service technician may need a particular tool at a site. A truck driver may need a route that avoids low bridges or unsuitable roads. A care service may need reliable arrival times. A mobile maintenance team may need to minimize travel while keeping urgent jobs first.

Route planning also supports teamwork. Dispatchers, drivers, warehouse staff, customer-service staff, supervisors, and clients may all depend on the same plan. A clear route sheet reduces misunderstandings because it records locations, sequence, planned times, special access notes, and contact or escalation procedures.

Route, Schedule, and Tour

A route describes the path through a transport network. A schedule describes when activities should happen. A tour combines a sequence of stops with the route and timing between them. In real work these elements interact. Changing one stop can change the best path, the expected arrival time, and the loading order.

A route can be mathematically short and still be operationally poor. For example, a shorter road may have a vehicle restriction, heavy congestion, limited delivery access, or a customer that is not ready when you arrive. Professional planning therefore checks the whole job, not only distance.

Start with a Planning Brief

Before selecting a route, collect reliable data. Incorrect input produces an incorrect plan, even when the routing software works perfectly.

Planning data	Questions to check	Why it matters
Start and end points	Where does the vehicle or worker begin and finish?	The start and end shape the whole tour.
Stops	Are all addresses, entrances, coordinates, or site names correct?	A correct customer name with a wrong entrance can still cause delay.
Service requirements	What must be delivered, collected, repaired, inspected, or completed?	The task may require tools, loading space, staff, or special access.
Time windows	Is there an earliest or latest acceptable arrival?	A route can be short but fail the customer requirement.
Service time	How long will loading, unloading, paperwork, or on-site work take?	Travel time alone is not the total route time.
Vehicle profile	What are the vehicle height, width, length, weight, range, and capacity?	The route must be physically and legally suitable.
Network conditions	Are there closures, restrictions, tolls, congestion, weather issues, or seasonal limits?	Conditions can change feasibility and travel time.
Work rules	Which breaks, working-time rules, safety procedures, and company policies apply?	A feasible plan must comply with applicable rules and procedures.

Data Quality and Location Checks

Check the address before you optimize the route. Similar street names, duplicate house numbers, new developments, restricted entrances, large industrial sites, and incorrect coordinates can create errors. When possible, confirm the actual delivery or service entrance rather than only the postal address.

For critical jobs, record a second way to identify the location, such as coordinates, a gate name, a site contact, or a landmark. Keep personal and customer data only as required by your organization and applicable data-protection rules.

Maps, GNSS, and Navigation Tools

Digital route planners combine map data with routing rules and location data. A GNSS receiver can help determine position, while navigation software calculates and displays a route. These are different functions: positioning tells you where you are; routing suggests how to travel through the network.

A navigation device is useful, but it is not the final authority. You must still observe real road signs, barriers, temporary restrictions, site instructions, and safe driving practice. Never operate a device in a way that distracts you from the road.

This video explains the basic idea behind GPS positioning and why accurate timing and satellite signals matter.

Reading Maps and Symbols

A map uses symbols, colors, labels, lines, and scale to represent the real world. Before a journey, identify the road class, junctions, access roads, one-way sections, restricted zones, likely turning points, and useful backup routes. A paper map or offline map can be valuable when mobile data, a device, or a navigation service is unavailable.

This Ordnance Survey video shows how map symbols help you interpret a map. The exact symbols used in your workplace may differ, so always use the correct legend and local road information.

Constraints: What Makes a Route Feasible?

A constraint is a condition that limits the routes or schedules you can choose. Professional planning starts by separating hard constraints from soft preferences.

A hard constraint must be satisfied. Examples include a road that prohibits the vehicle, a bridge that is too low, a site that closes before arrival, a vehicle that cannot carry the load, or a legally required break. A soft constraint is a preference that can sometimes be traded against another goal, such as minimizing tolls, keeping the same driver with the same customer, or reducing empty travel.

Vehicle and Road Restrictions

The planned route must match the vehicle. Check restrictions that are relevant to the job, such as height, width, length, mass, axle limits, hazardous-goods restrictions, emission-zone requirements, or roads unsuitable for the vehicle class. Requirements vary by country and vehicle type, so use current official information and your employer's procedures.

A route-planning system may contain vehicle profiles, but the planner and driver still need to verify that the selected profile matches the actual vehicle and load.

Capacity and Loading Order

Capacity is not only the maximum mass. Depending on the job, you may also need to check volume, pallet positions, temperature zones, fragile goods, tool space, battery range, or passenger capacity. The stop sequence can also affect loading order. Goods needed first should be accessible without unsafe or unnecessary rehandling.

For pickup-and-delivery work, capacity changes during the tour. A vehicle that leaves the depot below its maximum capacity can still become overloaded after later collections if the sequence is poorly planned.

Time Windows and Service Time

A time window is the period in which a stop should be served. A planner must combine travel time with service time, loading time, expected waiting, breaks, and a realistic buffer. If a customer accepts delivery from 10:00 to 10:30, arriving nearby at 09:20 does not necessarily improve the plan if the vehicle must wait for forty minutes.

Use time estimates as planning values, not promises that conditions will never change. Where punctuality is important, allow a reasonable buffer and define how delays will be communicated.

Time, Distance, and Cost

A simple travel-time estimate is:

Travel time = distance ÷ average speed

This is only a starting point. In real work, average speed changes with road type, traffic, weather, urban stops, vehicle type, and time of day. A more useful total-duration model is:

Planned route duration = driving time + service time + loading time + breaks + expected waiting + buffer

Cost may include labor, fuel or energy, tolls, parking, vehicle use, overtime risk, missed-service costs, and other organization-specific factors. The lowest-distance route is therefore not automatically the lowest-cost route.

Worked Comparison

Assume your routing tool provides two feasible options for the same set of stops.

Measure	Route A	Route B
Distance	78 km	84 km
Driving time	1 h 55 min	1 h 45 min
Expected waiting	35 min	5 min
Service time	1 h 30 min	1 h 30 min
Planned total	4 h 00 min	3 h 20 min

Route A is shorter in distance, but Route B has a shorter planned total time because it fits the stop timing better. This example shows why you should define the planning objective before you compare alternatives.

Traffic and Changing Conditions

Historical travel times can help planning, but live conditions may differ. Congestion, incidents, road works, weather, public events, or loading delays can change the route during the day.

When conditions change, compare the impact on the whole tour. A detour that saves ten minutes now might make a later time window impossible. Replanning should therefore consider downstream stops, remaining capacity, breaks, customer priorities, and safe operating conditions.

From Shortest Paths to Multi-Stop Optimization

A road network can be represented as a graph. Intersections or locations become nodes, and road segments become edges. Each edge can carry a weight, such as distance, expected time, or cost.

A shortest-path algorithm finds a low-cost path between points according to the selected weights. Dijkstra's algorithm is a classic method for non-negative edge weights. In vocational route planning, the important idea is not to calculate the algorithm by hand, but to understand that software optimizes according to the data and objective it receives.

Vehicle Routing Problems

When several stops or several vehicles are involved, the task becomes a vehicle routing problem. The planner may need to assign stops to vehicles and determine the visit order while respecting capacity, time windows, pickup-and-delivery relationships, and other constraints.

For advanced study, the Google OR-Tools routing documentation shows examples of traveling-salesperson and vehicle-routing problems with constraints. Optimization software can produce strong solutions, but real-world data, safety checks, and professional judgment remain essential.

Replanning and Exception Management

A route plan is a controlled starting point, not a guarantee that the day will happen exactly as predicted. Professional route planning includes a response process for exceptions.

Exception	Immediate question	Professional response
Road closure	Is the planned path still legal and passable?	Stop using the blocked path, select a safe alternative, and check effects on later stops.
Customer delay	Will waiting cause another time window to fail?	Compare waiting with resequencing and communicate changes.
Vehicle problem	Is it safe and permitted to continue?	Follow the organization's safety and breakdown procedure before replanning.
New urgent job	Which existing commitments could be affected?	Recalculate priority, route, time, capacity, and customer impact.
Navigation mismatch	Does the digital instruction conflict with signs or site reality?	Follow actual restrictions and verify the location or route data.

Record important changes when your workplace requires it. Good records support handovers, customer communication, learning from repeated delays, and later improvement of planning data.

Communicating a Route Plan

A useful route plan should be easy for another trained person to understand. The exact format depends on the workplace, but it should make the sequence, timing, requirements, and exceptions visible.

Route-sheet field	Example content
Job identifier	Delivery round or service order reference
Vehicle or travel mode	Assigned vehicle and relevant profile
Start	Depot and planned departure
Stops	Verified locations in planned order
Timing	Planned arrival, service duration, and time window
Access notes	Gate, loading area, check-in point, or site instruction
Load or task notes	Quantity, pickup, delivery, tools, or service requirement
Contingency	Approved alternative route or escalation process

Avoid placing unnecessary personal information in a route sheet. Use the communication channels and data-handling rules approved by your organization.

Workplace Route-Planning Checklist

Before departure, confirm that the route is feasible for the actual vehicle or travel mode, all required stops are included, addresses and entrances are verified, service and loading times are realistic, time windows can be met, applicable restrictions and work rules are considered, and essential backup information is available.

During the route, compare actual progress with the plan, watch for signs and restrictions, update the responsible person when a significant delay or exception occurs, and replan only when it is safe to do so.

After the route, compare planned and actual performance. Repeated differences can reveal poor service-time estimates, unsuitable sequences, inaccurate map data, recurring congestion, or process problems that should be corrected for future plans.
