7 Simulation of Pedestrians Method Short description Static Fixed choice ratios set by the user Travel Time Dependence of choice ratios on the travel time of preceding pedestrians who have already finished the partial route Next free counter For approaching a set of parallel organized queues (respectively desks or counters) The dynamic route choice criterion Travel time The following steps are performed: ► Initially the pedestrians are distributed equally on all routes of the decision, until each route has been concluded by at least one pedestrian. ► VISSIM evaluates the travel times of the latest user-defined number of pedestrians who have concluded a route. (The default value of the userdefinable route choice method parameter is 10.) ► Travel time of route i = Ti is the average of travel times of this user-defined number of pedestrians (respectively the pedestrians who have arrived at the route destination so far). The following route choice parameters are provided: Option Description Best Route The user-defined percentage of pedestrians uses the best route, i.e. the route with the minimum travel time. In case of two best routes, either route is charged equally. All other pedestrians are split randomly among all other routes. Kirchhoff The probability of a route is calculated as the inverse of the travel time to the power of the user-defined exponent a divided by the sum of these powers for all routes: (1/TravTime_i)^a / SumOfAllRoutes_i (1/TravTime_i)^a Logit The probability of a route is calculated as exp to the power of (the negative travel time divided by the user-defined denominator) divided by the sum of these powers for all routes: exp(-TravTime_i/denominator) / SumOfAllRoutes_i exp(-TravTime_i/denominator) Inverse Logit The probability of a route is calculated as exp to the power of (the user-defined numerator divided by the travel time) divided by the sum of these powers for all routes: exp(numerator/TravTime_i) / SumOfAllRoutes_i exp(numerator/TravTime_i) 374 VISSIM 5.30-05 © PTV AG 2011

In the following cases, a partial routing decision can apply to a pedestrian: ► If the pedestrian enters an area carrying a partial routing decision. ► If the pedestrian starts to follow a new main route. This means, there are cases in which a partial routing decision is ignored, though following a partial routing decision could be expected under certain circumstances: ► Two areas called A and B carry a partial routing decision each (a and b). Area B is located completely within area A. Thus, a pedestrian will always step on area A first and might then step on area B, if applicable. The main route and the partial routes are defined in the following way: Partial routing decision b applies to the pedestrian, but partial routing decision a does not. However, partial routing decision a would become valid, if partial route b had been added to the main route. Nevertheless, partial routing decision a is not used – neither right after partial routing decision b nor when the pedestrian merely stands on area A after leaving from area B. ► During the simulation, a pedestrian enters the network and receives a main route. At his position, there are two more partial routing decisions called a and b. Partial route a leads to an area that also carries an intermediate destination of the pedestrian’s main route, but partial route b does not. Partial route b leads to an area that also carries an intermediate destination of partial route a. Nevertheless, only partial routing decision a is regarded, whereas partial routing decision b is not, since it is required for the check for existing partial routing decisions that a normal routing decision must have been performed. However, if partial routing decision b is not located directly at the position where the User Manual © PTV AG 2011 375
