Why Integrate Python with Maptitude for Route Planning?

Maptitude is known for its advanced GIS capabilities, and the Routing.Router class enhances these by allowing you to:

• Minimize travel time or distance
• Include rest stops to meet driving regulations
• Optimize routes for fuel efficiency
• Generate detailed reports for stakeholders

Using Python in conjunction with Maptitude unlocks a vast ecosystem of libraries like Pandas and NumPy, while also automating route planning and report generation. This combination empowers GIS professionals to optimize logistics, reduce costs, and streamline operations.

Getting Started with Routing.Router in Python

Let’s walk through a simple example of how to use the Routing.Router class with Python via the caliperpy package. This example calculates a route between multiple locations, optimizes for travel time, and generates an Excel report:

import caliperpy
?
# Connect to Maptitude
dk = caliperpy.Maptitude.connect()
?
# Define stops with coordinates and stop durations
RoutingPoints = [
    {"Coordinate": dk.Coord(-71259994, 42298892), "StopDuration": 30, "StopName": "Babson College"},
    {"Coordinate": dk.Coord(-71250024, 42341178), "StopDuration": 30, "StopName": "Lasell College"},
    {"Coordinate": dk.Coord(-71187232, 42298633), "StopDuration": 30, "StopName": "Mount Ida College"},
]
?
# Create router and set parameters
router = dk.CreateGisdkObject("gis_ui", "Routing.Router")
router.Minimize = "Time"
router.IncludeRestStops = True
router.TimeBetweenRests = 240  # 4 hours driving before a break
router.RestStopDuration = 15  # 15-minute rest stops
router.FuelPrice = 3.29
?
# Calculate the route
path = router.Calculate(RoutingPoints, None)
?
# Generate report if path is calculated
if path:
    print(f"Path Time: {path.Time} minutes, Distance: {path.Distance} miles")
    router.ExportToExcel({"PathObj": path, "FileName": "route_report.xlsx"})
else:
    print("Error: Path calculation failed.")        

Advanced Features: Optimize Routes with Rest Stops and Fuel Costs

The Routing.Router class offers powerful features for more complex scenarios, such as adding rest stops and accounting for fuel efficiency:

Rest Stops: You can enforce breaks to comply with driving regulations, e.g., stopping after 5 hours of driving:

router.TimeBetweenRests = 300  # 5 hours
router.RestStopDuration = 20   # 20 minutes per break        

Fuel Costs: Factor in city and highway fuel consumption

router.FuelConsumptionCity = 17  # MPG in city
router.FuelConsumptionHighway = 23  # MPG on highway
router.FuelPrice = 3.29  # per gallon        

Cost Calculation: Choose between fuel consumption-based or distance-based cost calculation:

router.DistanceBasedCostCalculation = False  # Prioritize fuel efficiency        

Automating Address Input from Excel Files

Automating route planning for a large set of addresses can be done seamlessly using Python and Maptitude. Here’s how you can import addresses from an Excel file and generate optimized routes:

import sys
import os
import caliperpy
import pandas as pd
from tkinter import Tk
from tkinter.filedialog import askopenfilename
?
# Select Excel file with addresses
def get_excel_file():
    Tk().withdraw()
    return askopenfilename(title="Select Excel File", filetypes=[("Excel files", "*.xlsx *.xls")])
?
# Read addresses from Excel file
def read_addresses_from_excel(file_path):
    df = pd.read_excel(file_path)
    address_col = df.columns[df.columns.str.contains('address', case=False)].tolist()[0]
    city_col = df.columns[df.columns.str.contains('city', case=False)].tolist()[0]
    zip_col = df.columns[df.columns.str.contains('zip', case=False)].tolist()[0]
    return df[[address_col, city_col, zip_col]].to_dict('records')
?
# Main routing logic
def main():
    excel_file = get_excel_file()
    addresses = read_addresses_from_excel(excel_file)
?
    # Connect to Maptitude
    dk = caliperpy.Maptitude.connect()
?
    # Define stops from Excel addresses
    stop_list = [
        {"address": addr['Address'], "city": addr['City'], "postal_code": addr['ZIP']}
        for addr in addresses
    ]
    
????# Calculate route with the stops
    router = dk.CreateGisdkObject("Routing.Router")
    path = router.Calculate(stop_list, None)
?
    # Generate Excel report
    if path:
        router.ExportToExcel({"PathObj": path, "FileName": "route_report.xlsx"})        

Real-World Applications of Routing.Router

The Routing.Router class can be applied in various industries for:

1. Delivery Fleet Optimization: Minimize delivery time and fuel costs for fleets.
2. Field Service Planning: Efficiently plan service routes while considering rest stops.
3. Trip Planning for Tour Operators: Optimize routes for tour groups to maximize experiences.
4. Emergency Response Routing: Calculate the fastest routes during emergencies

Conclusion: Enhance Your Logistics with Python and Maptitude

Combining the robust routing features of Maptitude with Python’s flexibility, GIS professionals can optimize routes, minimize costs, and generate detailed reports. Whether managing delivery fleets or planning service routes, Python’s integration with Maptitude takes your GIS workflows to the next level.
