MapInfo's street network analysis engine for drive time analysis, the routing of people, products and resources.
Point to Point Routing
Point to point routing allows a customer to specify a start and destination location and in return receive the shortest time or shortest distance route in both spatial feature and directions form. A robust set of server and client side preferences support this and related features. Some of these preferences include:
- Optimization of routes by either travel time or distance.
- Internalization of driving directions and the addition of directions' modules that provide complete control over text directions.
- Road type preferences that allow for the avoidance of particular road types such as major or minor roads.
- The ability to change speed limits on road segments and have the routing server consider this data, in certain instances it may be real time data, when generating optimized routes.
- The ability to focus routes allows one to control the amount of detailed travel information returned to the calling application.
- The ability to receive terse driving directions, ideal for limited display devices
Multi-point routing allows one to specify a start and destination location but also as many intermediate points as needed. The user has the ability to specify whether the server should build a multi-point route in an optimized or an ordered fashion. An ordered multi-point request will return a path with all stops in the order in which they were submitted, while an optimized multi-point request will return the most efficient path between all stops. In addition to point-to-point routing preferences, multi-point preferences provide control over such factors as a duration spent at a particular stop.
Drive Time Matrices
Using matrix routing allows one to find the shortest paths between a number of start points and a number of destinations, and return the route costs. The costs are the total time and distance of the individual route. The matrix route feature is extremely useful for situations such as the following. Given 500 start and 500 destination points, find the shortest paths between all the start points and all the destinations, and return the routes costs, i.e. their times and distances. Almost all the preferences applicable to route request are applicable to matrix route request.
Drive Time Polygons
An isochrone is a polygon or set of points representing an area that can be traversed in a network in a given amount of time from a specified starting point. An isodistance is a polygon or set of points representing the area that is a certain distance from the starting point. This boundary or polygon can then be used for further analysis and it is, for example, ideal for analyzing the customer base within a given distance from an existing or proposed location. Drive time polygon preferences allow one to control the creation or shape of the returned polygon through settings such as off road distance, ambient speed, islands, and simplication factor.
