Find the shortest route between two places that chinese
They account for a considerable proportion of all travelers, and their route choices tend to have a certain regularity and may be optimized by traffic measures. The path similarity is measured by overlap O. Travel time is the fundamental travel indicator and is selected as an example to calculate the deviation measures. The quantitative method of travel distance is the same as that of travel time.
R is the residual, AR denotes the absolute residual, and SD is the standard deviation. Results 3. Comparisons between Travel Path and the Shortest Path 3. General Results Excluding a small number of circular routes of the exact origins or trips with apparent detour behavior, effective paths in the working day and effective paths in the rest day were finally obtained to compare the deviations between the selected path and the shortest path.
Table 4 shows the situation of sampled residents in Chongqing who choose the shortest route to travel. On Monday, The shortest time path takes up On Saturday, According to the summary, the proportion of Chongqing residents choosing the shortest route including the shortest time and the shortest distance to travel on the weekday is On the weekend, Table 4 The proportion of residents choosing the shortest path in Chongqing.
Compared with Chongqing, the existing studies of cities worldwide have shown a smaller proportion of shortest path selection, and only the research of Minneapolis-St. Next, the study will analyze the deviation between the actual travel path and the shortest path for Chongqing residents.
Deviation between Travel Path and the Shortest Path The shortest distance path, the shortest time path, and the recommended path that coincide with the actual travel path provided by Baidu Maps can be compared with the actual path data. The statistical description results are shown in Table 5. The research results showed that the actual travel route selected by residents on the weekday consumed 3. The average distance was 1. Nevertheless, the deviation reached about 9 min and 2 km absolute residual.
Travelers saved 2 minutes on average after choosing the shortest time path compared with the shortest distance path but traveled 0. Table 5 The statistical description of the deviation between the actual and shortest paths. However, we note that there is a deviation between the indexes of the actual path and the recommended path of the Baidu Maps which coincides with the actual path, so this deviation is used to correct the error between the actual path and the shortest path.
Compared with the shortest distance and time paths, the actual travel route selected by the residents consumes 0. Compared with the working day, the indicators of the rest day are more deviated. On the weekend, compared with the shortest distance and time paths, the actual travel route selected by residents consumed 3.
Although many Chinese urban residents still do not choose the shortest path, the deviation between the actual path and the shortest path is slight. Based on the residual error, the actual travel time of the selected path takes no more than 6 minutes on average, and the travel distance is no more than 1 km. Taking the absolute residual value as the benchmark, we found that the selected path takes no more than 9 minutes on average, and the travel distance is no more than 2 km.
Deviation between Similar Route Pairs This section uses the same OD paths of the same resident to conduct a preliminary comparative analysis of the travel paths. The path similarity is shown in Table 6. There are trips The commuters usually have a relatively fixed OD and route. They account for a considerable proportion, and their route choices tend to have a certain regularity and may be optimized by some measures.
Thus, uncovering the similarity of commuter routes is of importance to design more targeted measures. In the total path of the rest day, there were trips The weekend does not differentiate between activity types. Table 6 Trip paths similarity of residents in Chongqing. Table 7 shows the comparative analysis of the residuals of three indexes of travel time, distance, and travel speed of different path pairs.
The average absolute value of travel time residual of all samples is Moreover, the average absolute value of the travel speed residual is 7. The absolute standard deviations of the residual values corresponding to each index are The differences of each index of the same and similar path pairs are less than the whole. However, the difference between different paths is greater than the whole. Table 7 Absolute residual values and standard deviations of trip indicators for the path pairs.
When the activity types are considered, the average absolute residual value of the commuting time is The average absolute value of the distance residual is 1. A solution to optimally visit ALL edges in a network falls under a class of problems called arc routing, also known as Chinese Postman or an Euler tour.
Network Analyst does not provide a solution for that class of problems. BUT it can provide a solution to best visit a set of points, also called a travelling salesman problem TSP. So you could place a point on edge and optimize it. But there are many caveats to using a TSP solution for all edges in a city.

Distance between cities or 2 locations are measured in both kilometers, miles and nautical miles at the same time. Air distance is the bird fly distance between two locations which is calculated with the great circle formula. How to calculate the return distance between two places? To calculate the return distance between two places, start by entering start and end locations and then click on return distance to check the distance traveled in return.
You can also check the return distance by other travel modes like bus, subway, tram, train and rail. To find the shortest road distance between the two places, please enter the source and destination and then select the driving mode. How is distance related to time and speed? Which is the formula for distance and speed? We all have somewhere to be and we want to take the shortest route possible. This is even more true for delivery drivers and sales reps, who often have many different stops to make every day.
Luckily, there are tools you can use to find the shortest route for multiple destinations. Google Maps is one of the most popular, although it does have some drawbacks. Enter your destination into the search bar. Google will offer you several different route options with the distance and travel time displayed next to them. If your preference is for the shortest route select the one with the least distance. The shortest route is the one that covers the least amount of distance, whereas the fastest route is the one that takes the least amount of time.
This will largely depend on traffic conditions. Google is able to identify traffic delays using real-time data and determine both the shortest and fastest route. You can then choose which you prefer. Some people prioritize getting somewhere as fast as possible while others want to take the easiest and most direct route.
Are you familiar with the area? The fastest routes are sometimes more complicated and take you through back roads. Which route contains fewer left turns? This is often a dangerous maneuver, especially on busy streets.
